   Socrates. One, two, three; but where, my dear Timaeus, is the fourth
 of those who were yesterday my guests and are to be my entertainers
   Timaeus. He has been taken ill, Socrates; for he would not willingly
 have been absent from this gathering.
   Soc. Then, if he is not coming, you and the two others must supply
 his place.
   Tim. Certainly, and we will do all that we can; having been
 handsomely entertained by you yesterday, those of us who remain should
 be only too glad to return your hospitality.
   Soc. Do you remember what were the points of which I required you to
   Tim. We remember some of them, and you will be here to remind us
 of anything which we have forgotten: or rather, if we are not
 troubling you, will you briefly recapitulate the whole, and then the
 particulars will be more firmly fixed in our memories?
   Soc. To be sure I will: the chief theme of my yesterday's
 discourse was the State-how constituted and of what citizens
 composed it would seem likely to be most perfect.
   Tim. Yes, Socrates; and what you said of it was very much to our
   Soc. Did we not begin by separating the husbandmen and the
 artisans from the class of defenders of the State?
   Tim. Yes.
   Soc. And when we had given to each one that single employment and
 particular art which was suited to his nature, we spoke of those who
 were intended to be our warriors, and said that they were to be
 guardians of the city against attacks from within as well as from
 without, and to have no other employment; they were to be merciful
 in judging their subjects, of whom they were by nature friends, but
 fierce to their enemies, when they came across them in battle.
   Tim. Exactly.
   Soc. We said, if I am not mistaken, that the guardians should be
 gifted with a temperament in a high degree both passionate and
 philosophical; and that then they would be as they ought to be, gentle
 to their friends and fierce with their enemies.
   Tim. Certainly.
   Soc. And what did we say of their education? Were they not to be
 trained in gymnastic, and music, and all other sorts of knowledge
 which were proper for them?
   Tim. Very true.
   Soc. And being thus trained they were not to consider gold or silver
 or anything else to be their own private property; they were to be
 like hired troops, receiving pay for keeping guard from those who were
 protected by them-the pay was to be no more than would suffice for men
 of simple life; and they were to spend in common, and to live together
 in the continual practice of virtue, which was to be their sole
   Tim. That was also said.
   Soc. Neither did we forget the women; of whom we declared, that
 their natures should be assimilated and brought into harmony with
 those of the men, and that common pursuits should be assigned to
 them both in time of war and in their ordinary life.
   Tim. That, again, was as you say.
   Soc. And what about the procreation of children? Or rather not the
 proposal too singular to be forgotten? for all wives and children were
 to be in common, to the intent that no one should ever know his own
 child, but they were to imagine that they were all one family; those
 who were within a suitable limit of age were to be brothers and
 sisters, those who were of an elder generation parents and
 grandparents, and those of a younger children and grandchildren.
   Tim. Yes, and the proposal is easy to remember, as you say.
   Soc. And do you also remember how, with a view of securing as far as
 we could the best breed, we said that the chief magistrates, male
 and female, should contrive secretly, by the use of certain lots, so
 to arrange the nuptial meeting, that the bad of either sex and the
 good of either sex might pair with their like; and there was to be
 no quarrelling on this account, for they would imagine that the
 union was a mere accident, and was to be attributed to the lot?
   Tim. I remember.
   Soc. And you remember how we said that the children of the good
 parents were to be educated, and the children of the bad secretly
 dispersed among the inferior citizens; and while they were all growing
 up the rulers were to be on the look-out, and to bring up from below
 in their turn those who were worthy, and those among themselves who
 were unworthy were to take the places of those who came up?
   Tim. True.
   Soc. Then have I now given you all the heads of our yesterday's
 discussion? Or is there anything more, my dear Timaeus, which has been
   Tim. Nothing, Socrates; it was just as you have said.
   Soc. I should like, before proceeding further, to tell you how I
 feel about the State which we have described. I might compare myself
 to a person who, on beholding beautiful animals either created by
 the painter's art, or, better still, alive but at rest, is seized with
 a desire of seeing them in motion or engaged in some struggle or
 conflict to which their forms appear suited; this is my feeling
 about the State which we have been describing. There are conflicts
 which all cities undergo, and I should like to hear some one tell of
 our own city carrying on a struggle against her neighbours, and how
 she went out to war in a becoming manner, and when at war showed by
 the greatness of her actions and the magnanimity of her words in
 dealing with other cities a result worthy of her training and
 education. Now I, Critias and Hermocrates, am conscious that I
 myself should never be able to celebrate the city and her citizens
 in a befitting manner, and I am not surprised at my own incapacity; to
 me the wonder is rather that the poets present as well as past are
 no better-not that I mean to depreciate them; but every one can see
 that they are a tribe of imitators, and will imitate best and most
 easily the life in which they have been brought up; while that which
 is beyond the range of a man's education he finds hard to carry out in
 action, and still harder adequately to represent in language. I am
 aware that the Sophists have plenty of brave words and fair
 conceits, but I am afraid that being only wanderers from one city to
 another, and having never had habitations of their own, they may
 fail in their conception of philosophers and statesmen, and may not
 know what they do and say in time of war, when they are fighting or
 holding parley with their enemies. And thus people of your class are
 the only ones remaining who are fitted by nature and education to take
 part at once both in politics and philosophy. Here is Timaeus, of
 Locris in Italy, a city which has admirable laws, and who is himself
 in wealth and rank the equal of any of his fellow-citizens; he has
 held the most important and honourable offices in his own state,
 and, as I believe, has scaled the heights of all philosophy; and
 here is Critias, whom every Athenian knows to be no novice in the
 matters of which we are speaking; and as to, Hermocrates, I am assured
 by many witnesses that his genius and education qualify him to take
 part in any speculation of the kind. And therefore yesterday when I
 saw that you wanted me to describe the formation of the State, I
 readily assented, being very well aware, that, if you only would, none
 were better qualified to carry the discussion further, and that when
 you had engaged our city in a suitable war, you of all men living
 could best exhibit her playing a fitting part. When I had completed my
 task, I in return imposed this other task upon you. You conferred
 together and agreed to entertain me to-day, as I had entertained
 you, with a feast of discourse. Here am I in festive array, and no man
 can be more ready for the promised banquet.
   Her. And we too, Socrates, as Timaeus says, will not be wanting in
 enthusiasm; and there is no excuse for not complying with your
 request. As soon as we arrived yesterday at the guest-chamber of
 Critias, with whom we are staying, or rather on our way thither, we
 talked the matter over, and he told us an ancient tradition, which I
 wish, Critias, that you would repeat to Socrates, so that he may
 help us to judge whether it will satisfy his requirements or not.
   Crit. I will, if Timaeus, who is our other partner, approves.
   Tim. I quite approve.
   Crit. Then listen, Socrates, to a tale which, though strange, is
 certainly true, having been attested by Solon, who was the wisest of
 the seven sages. He was a relative and a dear friend of my
 great-grandfather, Dropides, as he himself says in many passages of
 his poems; and he told the story to Critias, my grandfather, who
 remembered and repeated it to us. There were of old, he said, great
 and marvellous actions of the Athenian city, which have passed into
 oblivion through lapse of time and the destruction of mankind, and one
 in particular, greater than all the rest. This we will now rehearse.
 It will be a fitting monument of our gratitude to you, and a hymn of
 praise true and worthy of the goddess, on this her day of festival.
   Soc. Very good. And what is this ancient famous action of the
 Athenians, which Critias declared, on the authority of Solon, to be
 not a mere legend, but an actual fact?
   Crit. I will tell an old-world story which I heard from an aged man;
 for Critias, at the time of telling it, was as he said, nearly
 ninety years of age, and I was about ten. Now the day was that day
 of the Apaturia which is called the Registration of Youth, at which,
 according to custom, our parents gave prizes for recitations, and
 the poems of several poets were recited by us boys, and many of us
 sang the poems of Solon, which at that time had not gone out of
 fashion. One of our tribe, either because he thought so or to please
 Critias, said that in his judgment Solon was not only the wisest of
 men, but also the noblest of poets. The old man, as I very well
 remember, brightened up at hearing this and said, smiling: Yes,
 Amynander, if Solon had only, like other poets, made poetry the
 business of his life, and had completed the tale which he brought with
 him from Egypt, and had not been compelled, by reason of the
 factions and troubles which he found stirring in his own country
 when he came home, to attend to other matters, in my opinion he
 would have been as famous as Homer or Hesiod, or any poet.
   And what was the tale about, Critias? said Amynander.
   About the greatest action which the Athenians ever did, and which
 ought to have been the most famous, but, through the lapse of time and
 the destruction of the actors, it has not come down to us.
   Tell us, said the other, the whole story, and how and from whom
 Solon heard this veritable tradition.
   He replied:-In the Egyptian Delta, at the head of which the river
 Nile divides, there is a certain district which is called the district
 of Sais, and the great city of the district is also called Sais, and
 is the city from which King Amasis came. The citizens have a deity for
 their foundress; she is called in the Egyptian tongue Neith, and is
 asserted by them to be the same whom the Hellenes call Athene; they
 are great lovers of the Athenians, and say that they are in some way
 related to them. To this city came Solon, and was received there
 with great honour; he asked the priests who were most skilful in
 such matters, about antiquity, and made the discovery that neither
 he nor any other Hellene knew anything worth mentioning about the
 times of old. On one occasion, wishing to draw them on to speak of
 antiquity, he began to tell about the most ancient things in our
 part of the world-about Phoroneus, who is called "the first man,"
 and about Niobe; and after the Deluge, of the survival of Deucalion
 and Pyrrha; and he traced the genealogy of their descendants, and
 reckoning up the dates, tried to compute how many years ago the events
 of which he was speaking happened. Thereupon one of the priests, who
 was of a very great age, said: O Solon, Solon, you Hellenes are
 never anything but children, and there is not an old man among you.
 Solon in return asked him what he meant. I mean to say, he replied,
 that in mind you are all young; there is no old opinion handed down
 among you by ancient tradition, nor any science which is hoary with
 age. And I will tell you why. There have been, and will be again, many
 destructions of mankind arising out of many causes; the greatest
 have been brought about by the agencies of fire and water, and other
 lesser ones by innumerable other causes. There is a story, which
 even you have preserved, that once upon a time Paethon, the son of
 Helios, having yoked the steeds in his father's chariot, because he
 was not able to drive them in the path of his father, burnt up all
 that was upon the earth, and was himself destroyed by a thunderbolt.
 Now this has the form of a myth, but really signifies a declination of
 the bodies moving in the heavens around the earth, and a great
 conflagration of things upon the earth, which recurs after long
 intervals; at such times those who live upon the mountains and in
 dry and lofty places are more liable to destruction than those who
 dwell by rivers or on the seashore. And from this calamity the Nile,
 who is our never-failing saviour, delivers and preserves us. When,
 on the other hand, the gods purge the earth with a deluge of water,
 the survivors in your country are herdsmen and shepherds who dwell
 on the mountains, but those who, like you, live in cities are
 carried by the rivers into the sea. Whereas in this land, neither then
 nor at any other time, does the water come down from above on the
 fields, having always a tendency to come up from below; for which
 reason the traditions preserved here are the most ancient.
   The fact is, that wherever the extremity of winter frost or of
 summer does not prevent, mankind exist, sometimes in greater,
 sometimes in lesser numbers. And whatever happened either in your
 country or in ours, or in any other region of which we are informed-if
 there were any actions noble or great or in any other way
 remarkable, they have all been written down by us of old, and are
 preserved in our temples. Whereas just when you and other nations
 are beginning to be provided with letters and the other requisites
 of civilized life, after the usual interval, the stream from heaven,
 like a pestilence, comes pouring down, and leaves only those of you
 who are destitute of letters and education; and so you have to begin
 all over again like children, and know nothing of what happened in
 ancient times, either among us or among yourselves. As for those
 genealogies of yours which you just now recounted to us, Solon, they
 are no better than the tales of children. In the first place you
 remember a single deluge only, but there were many previous ones; in
 the next place, you do not know that there formerly dwelt in your land
 the fairest and noblest race of men which ever lived, and that you and
 your whole city are descended from a small seed or remnant of them
 which survived. And this was unknown to you, because, for many
 generations, the survivors of that destruction died, leaving no
 written word. For there was a time, Solon, before the great deluge
 of all, when the city which now is Athens was first in war and in
 every way the best governed of all cities, is said to have performed
 the noblest deeds and to have had the fairest constitution of any of
 which tradition tells, under the face of heaven.
   Solon marvelled at his words, and earnestly requested the priests to
 inform him exactly and in order about these former citizens. You are
 welcome to hear about them, Solon, said the priest, both for your
 own sake and for that of your city, and above all, for the sake of the
 goddess who is the common patron and parent and educator of both our
 cities. She founded your city a thousand years before ours,
 receiving from the Earth and Hephaestus the seed of your race, and
 afterwards she founded ours, of which the constitution is recorded
 in our sacred registers to be eight thousand years old. As touching
 your citizens of nine thousand years ago, I will briefly inform you of
 their laws and of their most famous action; the exact particulars of
 the whole we will hereafter go through at our leisure in the sacred
 registers themselves. If you compare these very laws with ours you
 will find that many of ours are the counterpart of yours as they
 were in the olden time. In the first place, there is the caste of
 priests, which is separated from all the others; next, there are the
 artificers, who ply their several crafts by themselves and do not
 intermix; and also there is the class of shepherds and of hunters,
 as well as that of husbandmen; and you will observe, too, that the
 warriors in Egypt are distinct from all the other classes, and are
 commanded by the law to devote themselves solely to military pursuits;
 moreover, the weapons which they carry are shields and spears, a style
 of equipment which the goddess taught of Asiatics first to us, as in
 your part of the world first to you. Then as to wisdom, do you observe
 how our law from the very first made a study of the whole order of
 things, extending even to prophecy and medicine which gives health,
 out of these divine elements deriving what was needful for human life,
 and adding every sort of knowledge which was akin to them. All this
 order and arrangement the goddess first imparted to you when
 establishing your city; and she chose the spot of earth in which you
 were born, because she saw that the happy temperament of the seasons
 in that land would produce the wisest of men. Wherefore the goddess,
 who was a lover both of war and of wisdom, selected and first of all
 settled that spot which was the most likely to produce men likest
 herself. And there you dwelt, having such laws as these and still
 better ones, and excelled all mankind in all virtue, as became the
 children and disciples of the gods.
   Many great and wonderful deeds are recorded of your state in our
 histories. But one of them exceeds all the rest in greatness and
 valour. For these histories tell of a mighty power which unprovoked
 made an expedition against the whole of Europe and Asia, and to
 which your city put an end. This power came forth out of the
 Atlantic Ocean, for in those days the Atlantic was navigable; and
 there was an island situated in front of the straits which are by
 you called the Pillars of Heracles; the island was larger than Libya
 and Asia put together, and was the way to other islands, and from
 these you might pass to the whole of the opposite continent which
 surrounded the true ocean; for this sea which is within the Straits of
 Heracles is only a harbour, having a narrow entrance, but that other
 is a real sea, and the surrounding land may be most truly called a
 boundless continent. Now in this island of Atlantis there was a
 great and wonderful empire which had rule over the whole island and
 several others, and over parts of the continent, and, furthermore, the
 men of Atlantis had subjected the parts of Libya within the columns of
 Heracles as far as Egypt, and of Europe as far as Tyrrhenia. This vast
 power, gathered into one, endeavoured to subdue at a blow our
 country and yours and the whole of the region within the straits;
 and then, Solon, your country shone forth, in the excellence of her
 virtue and strength, among all mankind. She was pre-eminent in courage
 and military skill, and was the leader of the Hellenes. And when the
 rest fell off from her, being compelled to stand alone, after having
 undergone the very extremity of danger, she defeated and triumphed
 over the invaders, and preserved from slavery those who were not yet
 subjugated, and generously liberated all the rest of us who dwell
 within the pillars. But afterwards there occurred violent
 earthquakes and floods; and in a single day and night of misfortune
 all your warlike men in a body sank into the earth, and the island
 of Atlantis in like manner disappeared in the depths of the sea. For
 which reason the sea in those parts is impassable and impenetrable,
 because there is a shoal of mud in the way; and this was caused by the
 subsidence of the island.
   I have told you briefly, Socrates, what the aged Critias heard
 from Solon and related to us. And when you were speaking yesterday
 about your city and citizens, the tale which I have just been
 repeating to you came into my mind, and I remarked with astonishment
 how, by some mysterious coincidence, you agreed in almost every
 particular with the narrative of Solon; but I did not like to speak at
 the moment. For a long time had elapsed, and I had forgotten too much;
 I thought that I must first of all run over the narrative in my own
 mind, and then I would speak. And so I readily assented to your
 request yesterday, considering that in all such cases the chief
 difficulty is to find a tale suitable to our purpose, and that with
 such a tale we should be fairly well provided.
   And therefore, as Hermocrates has told you, on my way home yesterday
 I at once communicated the tale to my companions as I remembered it;
 and after I left them, during the night by thinking I recovered nearly
 the whole it. Truly, as is often said, the lessons of our childhood
 make wonderful impression on our memories; for I am not sure that I
 could remember all the discourse of yesterday, but I should be much
 surprised if I forgot any of these things which I have heard very long
 ago. I listened at the time with childlike interest to the old man's
 narrative; he was very ready to teach me, and I asked him again and
 again to repeat his words, so that like an indelible picture they were
 branded into my mind. As soon as the day broke, I rehearsed them as he
 spoke them to my companions, that they, as well as myself, might
 have something to say. And now, Socrates, to make an end my preface, I
 am ready to tell you the whole tale. I will give you not only the
 general heads, but the particulars, as they were told to me. The
 city and citizens, which you yesterday described to us in fiction,
 we will now transfer to the world of reality. It shall be the
 ancient city of Athens, and we will suppose that the citizens whom you
 imagined, were our veritable ancestors, of whom the priest spoke; they
 will perfectly harmonise, and there will be no inconsistency in saying
 that the citizens of your republic are these ancient Athenians. Let us
 divide the subject among us, and all endeavour according to our
 ability gracefully to execute the task which you have imposed upon us.
 Consider then, Socrates, if this narrative is suited to the purpose,
 or whether we should seek for some other instead.
   Soc. And what other, Critias, can we find that will be better than
 this, which is natural and suitable to the festival of the goddess,
 and has the very great advantage of being a fact and not a fiction?
 How or where shall we find another if we abandon this? We cannot,
 and therefore you must tell the tale, and good luck to you; and I in
 return for my yesterday's discourse will now rest and be a listener.
   Crit. Let me proceed to explain to you, Socrates, the order in which
 we have arranged our entertainment. Our intention is, that Timaeus,
 who is the most of an astronomer amongst us, and has made the nature
 of the universe his special study, should speak first, beginning
 with the generation of the world and going down to the creation of
 man; next, I am to receive the men whom he has created of whom some
 will have profited by the excellent education which you have given
 them; and then, in accordance with the tale of Solon, and equally with
 his law, we will bring them into court and make them citizens, as if
 they were those very Athenians whom the sacred Egyptian record has
 recovered from oblivion, and thenceforward we will speak of them as
 Athenians and fellow-citizens.
   Soc. I see that I shall receive in my turn a perfect and splendid
 feast of reason. And now, Timaeus, you, I suppose, should speak
 next, after duly calling upon the Gods.
   Tim. All men, Socrates, who have any degree of right feeling, at the
 beginning of every enterprise, whether small or great, always call
 upon God. And we, too, who are going to discourse of the nature of the
 universe, how created or how existing without creation, if we be not
 altogether out of our wits, must invoke the aid of Gods and
 Goddesses and pray that our words may be acceptable to them and
 consistent with themselves. Let this, then, be our invocation of the
 Gods, to which I add an exhortation of myself to speak in such
 manner as will be most intelligible to you, and will most accord
 with my own intent.
   First then, in my judgment, we must make a distinction and ask, What
 is that which always is and has no becoming; and what is that which is
 always becoming and never is? That which is apprehended by
 intelligence and reason is always in the same state; but that which is
 conceived by opinion with the help of sensation and without reason, is
 always in a process of becoming and perishing and never really is. Now
 everything that becomes or is created must of necessity be created
 by some cause, for without a cause nothing can be created. The work of
 the creator, whenever he looks to the unchangeable and fashions the
 form and nature of his work after an unchangeable pattern, must
 necessarily be made fair and perfect; but when he looks to the created
 only, and uses a created pattern, it is not fair or perfect. Was the
 heaven then or the world, whether called by this or by any other
 more appropriate name-assuming the name, I am asking a question
 which has to be asked at the beginning of an enquiry about
 anything-was the world, I say, always in existence and without
 beginning? or created, and had it a beginning? Created, I reply, being
 visible and tangible and having a body, and therefore sensible; and
 all sensible things are apprehended by opinion and sense and are in
 a process of creation and created. Now that which is created must,
 as we affirm, of necessity be created by a cause. But the father and
 maker of all this universe is past finding out; and even if we found
 him, to tell of him to all men would be impossible. And there is still
 a question to be asked about him: Which of the patterns had the
 artificer in view when he made the world-the pattern of the
 unchangeable, or of that which is created? If the world be indeed fair
 and the artificer good, it is manifest that he must have looked to
 that which is eternal; but if what cannot be said without blasphemy is
 true, then to the created pattern. Every one will see that he must
 have looked to, the eternal; for the world is the fairest of creations
 and he is the best of causes. And having been created in this way, the
 world has been framed in the likeness of that which is apprehended
 by reason and mind and is unchangeable, and must therefore of
 necessity, if this is admitted, be a copy of something. Now it is
 all-important that the beginning of everything should be according
 to nature. And in speaking of the copy and the original we may
 assume that words are akin to the matter which they describe; when
 they relate to the lasting and permanent and intelligible, they
 ought to be lasting and unalterable, and, as far as their nature
 allows, irrefutable and immovable-nothing less. But when they
 express only the copy or likeness and not the eternal things
 themselves, they need only be likely and analogous to the real
 words. As being is to becoming, so is truth to belief. If then,
 Socrates, amid the many opinions about the gods and the generation
 of the universe, we are not able to give notions which are
 altogether and in every respect exact and consistent with one another,
 do not be surprised. Enough, if we adduce probabilities as likely as
 any others; for we must remember that I who am the speaker, and you
 who are the judges, are only mortal men, and we ought to accept the
 tale which is probable and enquire no further.
   Soc. Excellent, Timaeus; and we will do precisely as you bid us. The
 prelude is charming, and is already accepted by us-may we beg of you
 to proceed to the strain?
   Tim. Let me tell you then why the creator made this world of
 generation. He was good, and the good can never have any jealousy of
 anything. And being free from jealousy, he desired that all things
 should be as like himself as they could be. This is in the truest
 sense the origin of creation and of the world, as we shall do well
 in believing on the testimony of wise men: God desired that all things
 should be good and nothing bad, so far as this was attainable.
 Wherefore also finding the whole visible sphere not at rest, but
 moving in an irregular and disorderly fashion, out of disorder he
 brought order, considering that this was in every way better than
 the other. Now the deeds of the best could never be or have been other
 than the fairest; and the creator, reflecting on the things which
 are by nature visible, found that no unintelligent creature taken as a
 whole was fairer than the intelligent taken as a whole; and that
 intelligence could not be present in anything which was devoid of
 soul. For which reason, when he was framing the universe, he put
 intelligence in soul, and soul in body, that he might be the creator
 of a work which was by nature fairest and best. Wherefore, using the
 language of probability, we may say that the world became a living
 creature truly endowed with soul and intelligence by the providence of
   This being supposed, let us proceed to the next stage: In the
 likeness of what animal did the Creator make the world? It would be an
 unworthy thing to liken it to any nature which exists as a part
 only; for nothing can be beautiful which is like any imperfect
 thing; but let us suppose the world to be the very image of that whole
 of which all other animals both individually and in their tribes are
 portions. For the original of the universe contains in itself all
 intelligible beings, just as this world comprehends us and all other
 visible creatures. For the Deity, intending to make this world like
 the fairest and most perfect of intelligible beings, framed one
 visible animal comprehending within itself all other animals of a
 kindred nature. Are we right in saying that there is one world, or
 that they are many and infinite? There must be one only, if the
 created copy is to accord with the original. For that which includes
 all other intelligible creatures cannot have a second or companion; in
 that case there would be need of another living being which would
 include both, and of which they would be parts, and the likeness would
 be more truly said to resemble not them, but that other which included
 them. In order then that the world might be solitary, like the perfect
 animal, the creator made not two worlds or an infinite number of them;
 but there is and ever will be one only-begotten and created heaven.
   Now that which is created is of necessity corporeal, and also
 visible and tangible. And nothing is visible where there is no fire,
 or tangible which has no solidity, and nothing is solid without earth.
 Wherefore also God in the beginning of creation made the body of the
 universe to consist of fire and earth. But two things cannot be
 rightly put together without a third; there must be some bond of union
 between them. And the fairest bond is that which makes the most
 complete fusion of itself and the things which it combines; and
 proportion is best adapted to effect such a union. For whenever in any
 three numbers, whether cube or square, there is a mean, which is to
 the last term what the first term is to it; and again, when the mean
 is to the first term as the last term is to the mean-then the mean
 becoming first and last, and the first and last both becoming means,
 they will all of them of necessity come to be the same, and having
 become the same with one another will be all one. If the universal
 frame had been created a surface only and having no depth, a single
 mean would have sufficed to bind together itself and the other
 terms; but now, as the world must be solid, and solid bodies are
 always compacted not by one mean but by two, God placed water and
 air in the mean between fire and earth, and made them to have the same
 proportion so far as was possible (as fire is to air so is air to
 water, and as air is to water so is water to earth); and thus he bound
 and put together a visible and tangible heaven. And for these reasons,
 and out of such elements which are in number four, the body of the
 world was created, and it was harmonised by proportion, and
 therefore has the spirit of friendship; and having been reconciled
 to itself, it was indissoluble by the hand of any other than the
   Now the creation took up the whole of each of the four elements; for
 the Creator compounded the world out of all the fire and all the water
 and all the air and all the earth, leaving no part of any of them
 nor any power of them outside. His intention was, in the first
 place, that the animal should be as far as possible a perfect whole
 and of perfect parts: secondly, that it should be one, leaving no
 remnants out of which another such world might be created: and also
 that it should be free from old age and unaffected by disease.
 Considering that if heat and cold and other powerful forces which
 unite bodies surround and attack them from without when they are
 unprepared, they decompose them, and by bringing diseases and old
 age upon them, make them waste away-for this cause and on these
 grounds he made the world one whole, having every part entire, and
 being therefore perfect and not liable to old age and disease. And
 he gave to the world the figure which was suitable and also natural.
 Now to the animal which was to comprehend all animals, that figure was
 suitable which comprehends within itself all other figures.
 Wherefore he made the world in the form of a globe, round as from a
 lathe, having its extremes in every direction equidistant from the
 centre, the most perfect and the most like itself of all figures;
 for he considered that the like is infinitely fairer than the
 unlike. This he finished off, making the surface smooth all around for
 many reasons; in the first place, because the living being had no need
 of eyes when there was nothing remaining outside him to be seen; nor
 of ears when there was nothing to be heard; and there was no
 surrounding atmosphere to be breathed; nor would there have been any
 use of organs by the help of which he might receive his food or get
 rid of what he had already digested, since there was nothing which
 went from him or came into him: for there was nothing beside him. Of
 design he was created thus, his own waste providing his own food,
 and all that he did or suffered taking place in and by himself. For
 the Creator conceived that a being which was self-sufficient would
 be far more excellent than one which lacked anything; and, as he had
 no need to take anything or defend himself against any one, the
 Creator did not think it necessary to bestow upon him hands: nor had
 he any need of feet, nor of the whole apparatus of walking; but the
 movement suited to his spherical form was assigned to him, being of
 all the seven that which is most appropriate to mind and intelligence;
 and he was made to move in the same manner and on the same spot,
 within his own limits revolving in a circle. All the other six motions
 were taken away from him, and he was made not to partake of their
 deviations. And as this circular movement required no feet, the
 universe was created without legs and without feet.
   Such was the whole plan of the eternal God about the god that was to
 be, to whom for this reason he gave a body, smooth and even, having
 a surface in every direction equidistant from the centre, a body
 entire and perfect, and formed out of perfect bodies. And in the
 centre he put the soul, which he diffused throughout the body,
 making it also to be the exterior environment of it; and he made the
 universe a circle moving in a circle, one and solitary, yet by
 reason of its excellence able to converse with itself, and needing
 no other friendship or acquaintance. Having these purposes in view
 he created the world a blessed god.
   Now God did not make the soul after the body, although we are
 speaking of them in this order; for having brought them together he
 would never have allowed that the elder should be ruled by the
 younger; but this is a random manner of speaking which we have,
 because somehow we ourselves too are very much under the dominion of
 chance. Whereas he made the soul in origin and excellence prior to and
 older than the body, to be the ruler and mistress, of whom the body
 was to be the subject. And he made her out of the following elements
 and on this wise: Out of the indivisible and unchangeable, and also
 out of that which is divisible and has to do with material bodies,
 he compounded a third and intermediate kind of essence, partaking of
 the nature of the same and of the other, and this compound he placed
 accordingly in a mean between the indivisible, and the divisible and
 material. He took the three elements of the same, the other, and the
 essence, and mingled them into one form, compressing by force the
 reluctant and unsociable nature of the other into the same. When he
 had mingled them with the essence and out of three made one, he
 again divided this whole into as many portions as was fitting, each
 portion being a compound of the same, the other, and the essence.
 And he proceeded to divide after this manner:-First of all, he took
 away one part of the whole [1], and then he separated a second part
 which was double the first [2], and then he took away a third part
 which was half as much again as the second and three times as much
 as the first [3], and then he took a fourth part which was twice as
 much as the second [4], and a fifth part which was three times the
 third [9], and a sixth part which was eight times the first [8], and a
 seventh part which was twenty-seven times the first [27]. After this
 he filled up the double intervals [i.e. between 1, 2, 4, 8] and the
 triple [i.e. between 1, 3, 9, 27] cutting off yet other portions
 from the mixture and placing them in the intervals, so that in each
 interval there were two kinds of means, the one exceeding and exceeded
 by equal parts of its extremes [as for example 1, 4/3, 2, in which the
 mean 4/3 is one-third of 1 more than 1, and one-third of 2 less than
 2], the other being that kind of mean which exceeds and is exceeded by
 an equal number. Where there were intervals of 3/2 and of 4/3 and of
 9/8, made by the connecting terms in the former intervals, he filled
 up all the intervals of 4/3 with the interval of 9/8, leaving a
 fraction over; and the interval which this fraction expressed was in
 the ratio of 256 to 243. And thus the whole mixture out of which he
 cut these portions was all exhausted by him. This entire compound he
 divided lengthways into two parts, which he joined to one another at
 the centre like the letter X, and bent them into a circular form,
 connecting them with themselves and each other at the point opposite
 to their original meeting-point; and, comprehending them in a
 uniform revolution upon the same axis, he made the one the outer and
 the other the inner circle. Now the motion of the outer circle he
 called the motion of the same, and the motion of the inner circle
 the motion of the other or diverse. The motion of the same he
 carried round by the side to the right, and the motion of the
 diverse diagonally to the left. And he gave dominion to the motion
 of the same and like, for that he left single and undivided; but the
 inner motion he divided in six places and made seven unequal circles
 having their intervals in ratios of two-and three, three of each,
 and bade the orbits proceed in a direction opposite to one another;
 and three [Sun, Mercury, Venus] he made to move with equal
 swiftness, and the remaining four [Moon, Saturn, Mars, Jupiter] to
 move with unequal swiftness to the three and to one another, but in
 due proportion.
   Now when the Creator had framed the soul according to his will, he
 formed within her the corporeal universe, and brought the two
 together, and united them centre to centre. The soul, interfused
 everywhere from the centre to the circumference of heaven, of which
 also she is the external envelopment, herself turning in herself,
 began a divine beginning of never ceasing and rational life enduring
 throughout all time. The body of heaven is visible, but the soul is
 invisible, and partakes of reason and harmony, and being made by the
 best of intellectual and everlasting natures, is the best of things
 created. And because she is composed of the same and of the other
 and of the essence, these three, and is divided and united in due
 proportion, and in her revolutions returns upon herself, the soul,
 when touching anything which has essence, whether dispersed in parts
 or undivided, is stirred through all her powers, to declare the
 sameness or difference of that thing and some other; and to what
 individuals are related, and by what affected, and in what way and how
 and when, both in the world of generation and in the world of
 immutable being. And when reason, which works with equal truth,
 whether she be in the circle of the diverse or of the same-in
 voiceless silence holding her onward course in the sphere of the
 self-moved-when reason, I say, is hovering around the sensible world
 and when the circle of the diverse also moving truly imparts the
 intimations of sense to the whole soul, then arise opinions and
 beliefs sure and certain. But when reason is concerned with the
 rational, and the circle of the same moving smoothly declares it, then
 intelligence and knowledge are necessarily perfected. And if any one
 affirms that in which these two are found to be other than the soul,
 he will say the very opposite of the truth.
   When the father creator saw the creature which he had made moving
 and living, the created image of the eternal gods, he rejoiced, and in
 his joy determined to make the copy still more like the original;
 and as this was eternal, he sought to make the universe eternal, so
 far as might be. Now the nature of the ideal being was everlasting,
 but to bestow this attribute in its fulness upon a creature was
 impossible. Wherefore he resolved to have a moving image of
 eternity, and when he set in order the heaven, he made this image
 eternal but moving according to number, while eternity itself rests in
 unity; and this image we call time. For there were no days and
 nights and months and years before the heaven was created, but when he
 constructed the heaven he created them also. They are all parts of
 time, and the past and future are created species of time, which we
 unconsciously but wrongly transfer to the eternal essence; for we
 say that he "was," he "is," he "will be," but the truth is that "is"
 alone is properly attributed to him, and that "was" and "will be" only
 to be spoken of becoming in time, for they are motions, but that which
 is immovably the same cannot become older or younger by time, nor ever
 did or has become, or hereafter will be, older or younger, nor is
 subject at all to any of those states which affect moving and sensible
 things and of which generation is the cause. These are the forms of
 time, which imitates eternity and revolves according to a law of
 number. Moreover, when we say that what has become is become and
 what becomes is becoming, and that what will become is about to become
 and that the non-existent is non-existent-all these are inaccurate
 modes of expression. But perhaps this whole subject will be more
 suitably discussed on some other occasion.
   Time, then, and the heaven came into being at the same instant in
 order that, having been created together, if ever there was to be a
 dissolution of them, they might be dissolved together. It was framed
 after the pattern of the eternal nature, that it might resemble this
 as far as was possible; for the pattern exists from eternity, and
 the created heaven has been, and is, and will be, in all time. Such
 was the mind and thought of God in the creation of time. The sun and
 moon and five other stars, which are called the planets, were
 created by him in order to distinguish and preserve the numbers of
 time; and when he had made-their several bodies, he placed them in the
 orbits in which the circle of the other was revolving-in seven
 orbits seven stars. First, there was the moon in the orbit nearest the
 earth, and next the sun, in the second orbit above the earth; then
 came the morning star and the star sacred to Hermes, moving in
 orbits which have an equal swiftness with the sun, but in an
 opposite direction; and this is the reason why the sun and Hermes
 and Lucifer overtake and are overtaken by each other. To enumerate the
 places which he assigned to the other stars, and to give all the
 reasons why he assigned them, although a secondary matter, would
 give more trouble than the primary. These things at some future
 time, when we are at leisure, may have the consideration which they
 deserve, but not at present.
   Now, when all the stars which were necessary to the creation of time
 had attained a motion suitable to them,-and had become living
 creatures having bodies fastened by vital chains, and learnt their
 appointed task, moving in the motion of the diverse, which is
 diagonal, and passes through and is governed by the motion of the
 same, they revolved, some in a larger and some in a lesser orbit-those
 which had the lesser orbit revolving faster, and those which had the
 larger more slowly. Now by reason of the motion of the same, those
 which revolved fastest appeared to be overtaken by those which moved
 slower although they really overtook them; for the motion of the
 same made them all turn in a spiral, and, because some went one way
 and some another, that which receded most slowly from the sphere of
 the same, which was the swiftest, appeared to follow it most nearly.
 That there might be some visible measure of their relative swiftness
 and slowness as they proceeded in their eight courses, God lighted a
 fire, which we now call the sun, in the second from the earth of these
 orbits, that it might give light to the whole of heaven, and that
 the animals, as many as nature intended, might participate in
 number, learning arithmetic from the revolution of the same and the
 like. Thus then, and for this reason the night and the day were
 created, being the period of the one most intelligent revolution.
 And the month is accomplished when the moon has completed her orbit
 and overtaken the sun, and the year when the sun has completed his own
 orbit. Mankind, with hardly an exception, have not remarked the
 periods of the other stars, and they have no name for them, and do not
 measure them against one another by the help of number, and hence they
 can scarcely be said to know that their wanderings, being infinite
 in number and admirable for their variety, make up time. And yet there
 is no difficulty in seeing that the perfect number of time fulfils the
 perfect year when all the eight revolutions, having their relative
 degrees of swiftness, are accomplished together and attain their
 completion at the same time, measured by the rotation of the same
 and equally moving. After this manner, and for these reasons, came
 into being such of the stars as in their heavenly progress received
 reversals of motion, to the end that the created heaven might
 imitate the eternal nature, and be as like as possible to the
 perfect and intelligible animal.
   Thus far and until the birth of time the created universe was made
 in the likeness of the original, but inasmuch as all animals were
 not yet comprehended therein, it was still unlike. What remained,
 the creator then proceeded to fashion after the nature of the pattern.
 Now as in the ideal animal the mind perceives ideas or species of a
 certain nature and number, he thought that this created animal ought
 to have species of a like nature and number. There are four such;
 one of them is the heavenly race of the gods; another, the race of
 birds whose way is in the air; the third, the watery species; and
 the fourth, the pedestrian and land creatures. Of the heavenly and
 divine, he created the greater part out of fire, that they might be
 the brightest of all things and fairest to behold, and he fashioned
 them after the likeness of the universe in the figure of a circle, and
 made them follow the intelligent motion of the supreme, distributing
 them over the whole circumference of heaven, which was to be a true
 cosmos or glorious world spangled with them all over. And he gave to
 each of them two movements: the first, a movement on the same spot
 after the same manner, whereby they ever continue to think
 consistently the same thoughts about the same things; the second, a
 forward movement, in which they are controlled by the revolution of
 the same and the like; but by the other five motions they were
 unaffected, in order that each of them might attain the highest
 perfection. And for this reason the fixed stars were created, to be
 divine and eternal animals, ever-abiding and revolving after the
 same manner and on the same spot; and the other stars which reverse
 their motion and are subject to deviations of this kind, were
 created in the manner already described. The earth, which is our
 nurse, clinging around the pole which is extended through the
 universe, he framed to be the guardian and artificer of night and day,
 first and eldest of gods that are in the interior of heaven. Vain
 would be the attempt to tell all the figures of them circling as in
 dance, and their juxtapositions, and the return of them in their
 revolutions upon themselves, and their approximations, and to say
 which of these deities in their conjunctions meet, and which of them
 are in opposition, and in what order they get behind and before one
 another, and when they are severally eclipsed to our sight and again
 reappear, sending terrors and intimations of the future to those who
 cannot calculate their movements-to attempt to tell of all this
 without a visible representation of the heavenly system would be
 labour in vain. Enough on this head; and now let what we have said
 about the nature of the created and visible gods have an end.
   To know or tell the origin of the other divinities is beyond us, and
 we must accept the traditions of the men of old time who affirm
 themselves to be the offspring of the gods-that is what they say-and
 they must surely have known their own ancestors. How can we doubt
 the word of the children of the gods? Although they give no probable
 or certain proofs, still, as they declare that they are speaking of
 what took place in their own family, we must conform to custom and
 believe them. In this manner, then, according to them, the genealogy
 of these gods is to be received and set forth.
   Oceanus and Tethys were the children of Earth and Heaven, and from
 these sprang Phorcys and Cronos and Rhea, and all that generation; and
 from Cronos and Rhea sprang Zeus and Here, and all those who are
 said to be their brethren, and others who were the children of these.
   Now, when all of them, both those who visibly appear in their
 revolutions as well as those other gods who are of a more retiring
 nature, had come into being, the creator of the universe addressed
 them in these words: "Gods, children of gods, who are my works, and of
 whom I am the artificer and father, my creations are indissoluble,
 if so I will. All that is bound may be undone, but only an evil
 being would wish to undo that which is harmonious and happy.
 Wherefore, since ye are but creatures, ye are not altogether
 immortal and indissoluble, but ye shall certainly not be dissolved,
 nor be liable to the fate of death, having in my will a greater and
 mightier bond than those with which ye were bound at the time of
 your birth. And now listen to my instructions:-Three tribes of
 mortal beings remain to be created-without them the universe will be
 incomplete, for it will not contain every kind of animal which it
 ought to contain, if it is to be perfect. On the other hand, if they
 were created by me and received life at my hands, they would be on
 an equality with the gods. In order then that they may be mortal,
 and that this universe may be truly universal, do ye, according to
 your natures, betake yourselves to the formation of animals, imitating
 the power which was shown by me in creating you. The part of them
 worthy of the name immortal, which is called divine and is the guiding
 principle of those who are willing to follow justice and you-of that
 divine part I will myself sow the seed, and having made a beginning, I
 will hand the work over to you. And do ye then interweave the mortal
 with the immortal, and make and beget living creatures, and give
 them food, and make them to grow, and receive them again in death."
   Thus he spake, and once more into the cup in which he had previously
 mingled the soul of the universe he poured the remains of the
 elements, and mingled them in much the same manner; they were not,
 however, pure as before, but diluted to the second and third degree.
 And having made it he divided the whole mixture into souls equal in
 number to the stars, and assigned each soul to a star; and having
 there placed them as in a chariot, he showed them the nature of the
 universe, and declared to them the laws of destiny, according to which
 their first birth would be one and the same for all,-no one should
 suffer a disadvantage at his hands; they were to be sown in the
 instruments of time severally adapted to them, and to come forth the
 most religious of animals; and as human nature was of two kinds, the
 superior race would here after be called man. Now, when they should be
 implanted in bodies by necessity, and be always gaining or losing some
 part of their bodily substance, then in the first place it would be
 necessary that they should all have in them one and the same faculty
 of sensation, arising out of irresistible impressions; in the second
 place, they must have love, in which pleasure and pain mingle; also
 fear and anger, and the feelings which are akin or opposite to them;
 if they conquered these they would live righteously, and if they
 were conquered by them, unrighteously. He who lived well during his
 appointed time was to return and dwell in his native star, and there
 he would have a blessed and congenial existence. But if he failed in
 attaining this, at the second birth he would pass into a woman, and
 if, when in that state of being, he did not desist from evil, he would
 continually be changed into some brute who resembled him in the evil
 nature which he had acquired, and would not cease from his toils and
 transformations until he followed the revolution of the same and the
 like within him, and overcame by the help of reason the turbulent
 and irrational mob of later accretions, made up of fire and air and
 water and earth, and returned to the form of his first and better
 state. Having given all these laws to his creatures, that he might
 be guiltless of future evil in any of them, the creator sowed some
 of them in the earth, and some in the moon, and some in the other
 instruments of time; and when he had sown them he committed to the
 younger gods the fashioning of their mortal bodies, and desired them
 to furnish what was still lacking to the human soul, and having made
 all the suitable additions, to rule over them, and to pilot the mortal
 animal in the best and wisest manner which they could, and avert
 from him all but self-inflicted evils.
   When the creator had made all these ordinances he remained in his
 own accustomed nature, and his children heard and were obedient to
 their father's word, and receiving from him the immortal principle
 of a mortal creature, in imitation of their own creator they
 borrowed portions of fire, and earth, and water, and air from the
 world, which were hereafter to be restored-these they took and
 welded them together, not with the indissoluble chains by which they
 were themselves bound, but with little pegs too small to be visible,
 making up out of all the four elements each separate body, and
 fastening the courses of the immortal soul in a body which was in a
 state of perpetual influx and efflux. Now these courses, detained as
 in a vast river, neither overcame nor were overcome; but were hurrying
 and hurried to and fro, so that the whole animal was moved and
 progressed, irregularly however and irrationally and anyhow, in all
 the six directions of motion, wandering backwards and forwards, and
 right and left, and up and down, and in all the six directions. For
 great as was the advancing and retiring flood which provided
 nourishment, the affections produced by external contact caused
 still greater tumult-when the body of any one met and came into
 collision with some external fire, or with the solid earth or the
 gliding waters, or was caught in the tempest borne on the air, and the
 motions produced by any of these impulses were carried through the
 body to the soul. All such motions have consequently received the
 general name of "sensations," which they still retain. And they did in
 fact at that time create a very great and mighty movement; uniting
 with the ever flowing stream in stirring up and violently shaking
 the courses of the soul, they completely stopped the revolution of the
 same by their opposing current, and hindered it from predominating and
 advancing; and they so disturbed the nature of the other or diverse,
 that the three double intervals [i.e. between 1, 2, 4, 8], and the
 three triple intervals [i.e. between 1, 3, 9, 27], together with the
 mean terms and connecting links which are expressed by the ratios of 3
 : 2, and 4 : 3, and of 9 : 8-these, although they cannot be wholly
 undone except by him who united them, were twisted by them in all
 sorts of ways, and the circles were broken and disordered in every
 possible manner, so that when they moved they were tumbling to pieces,
 and moved irrationally, at one time in a reverse direction, and then
 again obliquely, and then upside down, as you might imagine a person
 who is upside down and has his head leaning upon the ground and his
 feet up against something in the air; and when he is in such a
 position, both he and the spectator fancy that the right of either
 is his left, and left right. If, when powerfully experiencing these
 and similar effects, the revolutions of the soul come in contact
 with some external thing, either of the class of the same or of the
 other, they speak of the same or of the other in a manner the very
 opposite of the truth; and they become false and foolish, and there is
 no course or revolution in them which has a guiding or directing
 power; and if again any sensations enter in violently from without and
 drag after them the whole vessel of the soul, then the courses of
 the soul, though they seem to conquer, are really conquered.
   And by reason of all these affections, the soul, when encased in a
 mortal body, now, as in the beginning, is at first without
 intelligence; but when the flood of growth and nutriment abates, and
 the courses of the soul, calming down, go their own way and become
 steadier as time goes on, then the several circles return to their
 natural form, and their revolutions are corrected, and they call the
 same and the other by their right names, and make the possessor of
 them to become a rational being. And if these combine in him with
 any true nurture or education, he attains the fulness and health of
 the perfect man, and escapes the worst disease of all; but if he
 neglects education he walks lame to the end of his life, and returns
 imperfect and good for nothing to the world below. This, however, is a
 later stage; at present we must treat more exactly the subject
 before us, which involves a preliminary enquiry into the generation of
 the body and its members, and as to how the soul was created-for
 what reason and by what providence of the gods; and holding fast to
 probability, we must pursue our way.
   First, then, the gods, imitating the spherical shape of the
 universe, enclosed the two divine courses in a spherical body, that,
 namely, which we now term the head, being the most divine part of us
 and the lord of all that is in us: to this the gods, when they put
 together the body, gave all the other members to be servants,
 considering that it partook of every sort of motion. In order then
 that it might not tumble about among the high and deep places of the
 earth, but might be able to get over the one and out of the other,
 they provided the body to be its vehicle and means of locomotion;
 which consequently had length and was furnished with four limbs
 extended and flexible; these God contrived to be instruments of
 locomotion with which it might take hold and find support, and so be
 able to pass through all places, carrying on high the dwelling-place
 of the most sacred and divine part of us. Such was the origin of
 legs and hands, which for this reason were attached to every man;
 and the gods, deeming the front part of man to be more honourable
 and more fit to command than the hinder part, made us to move mostly
 in a forward direction. Wherefore man must needs have his front part
 unlike and distinguished from the rest of his body.
   And so in the vessel of the head, they first of all put a face in
 which they inserted organs to minister in all things to the providence
 of the soul, and they appointed this part, which has authority, to
 be by nature the part which is in front. And of the organs they
 first contrived the eyes to give light, and the principle according to
 which they were inserted was as follows: So much of fire as would
 not burn, but gave a gentle light, they formed into a substance akin
 to the light of every-day life; and the pure fire which is within us
 and related thereto they made to flow through the eyes in a stream
 smooth and dense, compressing the whole eye, and especially the centre
 part, so that it kept out everything of a coarser nature, and
 allowed to pass only this pure element. When the light of day
 surrounds the stream of vision, then like falls upon like, and they
 coalesce, and one body is formed by natural affinity in the line of
 vision, wherever the light that falls from within meets with an
 external object. And the whole stream of vision, being similarly
 affected in virtue of similarity, diffuses the motions of what it
 touches or what touches it over the whole body, until they reach the
 soul, causing that perception which we call sight. But when night
 comes on and the external and kindred fire departs, then the stream of
 vision is cut off; for going forth to an unlike element it is
 changed and extinguished, being no longer of one nature with the
 surrounding atmosphere which is now deprived of fire: and so the eye
 no longer sees, and we feel disposed to sleep. For when the eyelids,
 which the gods invented for the preservation of sight, are closed,
 they keep in the internal fire; and the power of the fire diffuses and
 equalises the inward motions; when they are equalised, there is
 rest, and when the rest is profound, sleep comes over us scarce
 disturbed by dreams; but where the greater motions still remain, of
 whatever nature and in whatever locality, they engender
 corresponding visions in dreams, which are remembered by us when we
 are awake and in the external world. And now there is no longer any
 difficulty in understanding the creation of images in mirrors and
 all smooth and bright surfaces. For from the communion of the internal
 and external fires, and again from the union of them and their
 numerous transformations when they meet in the mirror, all these
 appearances of necessity arise, when the fire from the face
 coalesces with the fire from the eye on the bright and smooth surface.
 And right appears left and left right, because the visual rays come
 into contact with the rays emitted by the object in a manner
 contrary to the usual mode of meeting; but the right appears right,
 and the left left, when the position of one of the two concurring
 lights is reversed; and this happens when the mirror is concave and
 its smooth surface repels the right stream of vision to the left side,
 and the left to the right. Or if the mirror be turned vertically, then
 the concavity makes the countenance appear to be all upside down,
 and the lower rays are driven upwards and the upper downwards.
   All these are to be reckoned among the second and co-operative
 causes which God, carrying into execution the idea of the best as
 far as possible, uses as his ministers. They are thought by most men
 not to be the second, but the prime causes of all things, because they
 freeze and heat, and contract and dilate, and the like. But they are
 not so, for they are incapable of reason or intellect; the only
 being which can properly have mind is the invisible soul, whereas fire
 and water, and earth and air, are all of them visible bodies. The
 lover of intellect and knowledge ought to explore causes of
 intelligent nature first of all, and, secondly, of those things which,
 being moved by others, are compelled to move others. And this is
 what we too must do. Both kinds of causes should be acknowledged by
 us, but a distinction should be made between those which are endowed
 with mind and are the workers of things fair and good, and those which
 are deprived of intelligence and always produce chance effects without
 order or design. Of the second or co-operative causes of sight,
 which help to give to the eyes the power which they now possess,
 enough has been said. I will therefore now proceed to speak of the
 higher use and purpose for which God has given them to us. The sight
 in my opinion is the source of the greatest benefit to us, for had
 we never seen the stars, and the sun, and the heaven, none of the
 words which we have spoken about the universe would ever have been
 uttered. But now the sight of day and night, and the months and the
 revolutions of the years, have created number, and have given us a
 conception of time, and the power of enquiring about the nature of the
 universe; and from this source we have derived philosophy, than
 which no greater good ever was or will be given by the gods to
 mortal man. This is the greatest boon of sight: and of the lesser
 benefits why should I speak? even the ordinary man if he were deprived
 of them would bewail his loss, but in vain. Thus much let me say
 however: God invented and gave us sight to the end that we might
 behold the courses of intelligence in the heaven, and apply them to
 the courses of our own intelligence which are akin to them, the
 unperturbed to the perturbed; and that we, learning them and partaking
 of the natural truth of reason, might imitate the absolutely
 unerring courses of God and regulate our own vagaries. The same may be
 affirmed of speech and hearing: they have been given by the gods to
 the same end and for a like reason. For this is the principal end of
 speech, whereto it most contributes. Moreover, so much of music as
 is adapted to the sound of the voice and to the sense of hearing is
 granted to us for the sake of harmony; and harmony, which has
 motions akin to the revolutions of our souls, is not regarded by the
 intelligent votary of the Muses as given by them with a view to
 irrational pleasure, which is deemed to be the purpose of it in our
 day, but as meant to correct any discord which may have arisen in
 the courses of the soul, and to be our ally in bringing her into
 harmony and agreement with herself; and rhythm too was given by them
 for the same reason, on account of the irregular and graceless ways
 which prevail among mankind generally, and to help us against them.
   Thus far in what we have been saying, with small exception, the
 works of intelligence have been set forth; and now we must place by
 the side of them in our discourse the things which come into being
 through necessity-for the creation is mixed, being made up of
 necessity and mind. Mind, the ruling power, persuaded necessity to
 bring the greater part of created things to perfection, and thus and
 after this manner in the beginning, when the influence of reason got
 the better of necessity, the universe was created. But if a person
 will truly tell of the way in which the work was accomplished, he must
 include the other influence of the variable cause as well.
 Wherefore, we must return again and find another suitable beginning,
 as about the former matters, so also about these. To which end we must
 consider the nature of fire, and water, and air, and earth, such as
 they were prior to the creation of the heaven, and what was
 happening to them in this previous state; for no one has as yet
 explained the manner of their generation, but we speak of fire and the
 rest of them, whatever they mean, as though men knew their natures,
 and we maintain them to be the first principles and letters or
 elements of the whole, when they cannot reasonably be compared by a
 man of any sense even to syllables or first compounds. And let me
 say thus much: I will not now speak of the first principle or
 principles of all things, or by whatever name they are to be called,
 for this reason-because it is difficult to set forth my opinion
 according to the method of discussion which we are at present
 employing. Do not imagine, any more than I can bring myself to
 imagine, that I should be right in undertaking so great and
 difficult a task. Remembering what I said at first about
 probability, I will do my best to give as probable an explanation as
 any other-or rather, more probable; and I will first go back to the
 beginning and try to speak of each thing and of all. Once more,
 then, at the commencement of my discourse, I call upon God, and beg
 him to be our saviour out of a strange and unwonted enquiry, and to
 bring us to the haven of probability. So now let us begin again.
   This new beginning of our discussion of the universe requires a
 fuller division than the former; for then we made two classes, now a
 third must be revealed. The two sufficed for the former discussion:
 one, which we assumed, was a pattern intelligible and always the same;
 and the second was only the imitation of the pattern, generated and
 visible. There is also a third kind which we did not distinguish at
 the time, conceiving that the two would be enough. But now the
 argument seems to require that we should set forth in words another
 kind, which is difficult of explanation and dimly seen. What nature
 are we to attribute to this new kind of being? We reply, that it is
 the receptacle, and in a manner the nurse, of all generation. I have
 spoken the truth; but I must express myself in clearer language, and
 this will be an arduous task for many reasons, and in particular
 because I must first raise questions concerning fire and the other
 elements, and determine what each of them is; for to say, with any
 probability or certitude, which of them should be called water
 rather than fire, and which should be called any of them rather than
 all or some one of them, is a difficult matter. How, then, shall we
 settle this point, and what questions about the elements may be fairly
   In the first place, we see that what we just now called water, by
 condensation, I suppose, becomes stone and earth; and this same
 element, when melted and dispersed, passes into vapour and air. Air,
 again, when inflamed, becomes fire; and again fire, when condensed and
 extinguished, passes once more into the form of air; and once more,
 air, when collected and condensed, produces cloud and mist; and from
 these, when still more compressed, comes flowing water, and from water
 comes earth and stones once more; and thus generation appears to be
 transmitted from one to the other in a circle. Thus, then, as the
 several elements never present themselves in the same form, how can
 any one have the assurance to assert positively that any of them,
 whatever it may be, is one thing rather than another? No one can.
 But much the safest plan is to speak of them as follows:-Anything
 which we see to be continually changing, as, for example, fire, we
 must not call "this" or "that," but rather say that it is "of such a
 nature"; nor let us speak of water as "this"; but always as "such";
 nor must we imply that there is any stability in any of those things
 which we indicate by the use of the words "this" and "that," supposing
 ourselves to signify something thereby; for they are too volatile to
 be detained in any such expressions as "this," or "that," or "relative
 to this," or any other mode of speaking which represents them as
 permanent. We ought not to apply "this" to any of them, but rather the
 word "such"; which expresses the similar principle circulating in each
 and all of them; for example, that should be called "fire" which is of
 such a nature always, and so of everything that has generation. That
 in which the elements severally grow up, and appear, and decay, is
 alone to be called by the name "this" or "that"; but that which is
 of a certain nature, hot or white, or anything which admits of
 opposite equalities, and all things that are compounded of them, ought
 not to be so denominated. Let me make another attempt to explain my
 meaning more clearly. Suppose a person to make all kinds of figures of
 gold and to be always transmuting one form into all the
 rest-somebody points to one of them and asks what it is. By far the
 safest and truest answer is, That is gold; and not to call the
 triangle or any other figures which are formed in the gold "these," as
 though they had existence, since they are in process of change while
 he is making the assertion; but if the questioner be willing to take
 the safe and indefinite expression, "such," we should be satisfied.
 And the same argument applies to the universal nature which receives
 all bodies-that must be always called the same; for, while receiving
 all things, she never departs at all from her own nature, and never in
 any way, or at any time, assumes a form like that of any of the things
 which enter into her; she is the natural recipient of all impressions,
 and is stirred and informed by them, and appears different from time
 to time by reason of them. But the forms which enter into and go out
 of her are the likenesses of real existences modelled after their
 patterns in wonderful and inexplicable manner, which we will hereafter
 investigate. For the present we have only to conceive of three
 natures: first, that which is in process of generation; secondly, that
 in which the generation takes place; and thirdly, that of which the
 thing generated is a resemblance. And we may liken the receiving
 principle to a mother, and the source or spring to a father, and the
 intermediate nature to a child; and may remark further, that if the
 model is to take every variety of form, then the matter in which the
 model is fashioned will not be duly prepared, unless it is formless,
 and free from the impress of any of these shapes which it is hereafter
 to receive from without. For if the matter were like any of the
 supervening forms, then whenever any opposite or entirely different
 nature was stamped upon its surface, it would take the impression
 badly, because it would intrude its own shape. Wherefore, that which
 is to receive all forms should have no form; as in making perfumes
 they first contrive that the liquid substance which is to receive
 the scent shall be as inodorous as possible; or as those who wish to
 impress figures on soft substances do not allow any previous
 impression to remain, but begin by making the surface as even and
 smooth as possible. In the same way that which is to receive
 perpetually and through its whole extent the resemblances of all
 eternal beings ought to be devoid of any particular form. Wherefore,
 the mother and receptacle of all created and visible and in any way
 sensible things, is not to be termed earth, or air, or fire, or water,
 or any of their compounds or any of the elements from which these
 are derived, but is an invisible and formless being which receives all
 things and in some mysterious way partakes of the intelligible, and is
 most incomprehensible. In saying this we shall not be far wrong; as
 far, however, as we can attain to a knowledge of her from the previous
 considerations, we may truly say that fire is that part of her
 nature which from time to time is inflamed, and water that which is
 moistened, and that the mother substance becomes earth and air, in
 so far as she receives the impressions of them.
   Let us consider this question more precisely. Is there any
 self-existent fire? and do all those things which we call
 self-existent exist? or are only those things which we see, or in some
 way perceive through the bodily organs, truly existent, and nothing
 whatever besides them? And is all that which, we call an
 intelligible essence nothing at all, and only a name? Here is a
 question which we must not leave unexamined or undetermined, nor
 must we affirm too confidently that there can be no decision;
 neither must we interpolate in our present long discourse a digression
 equally long, but if it is possible to set forth a great principle
 in a few words, that is just what we want.
   Thus I state my view:-If mind and true opinion are two distinct
 classes, then I say that there certainly are these self-existent ideas
 unperceived by sense, and apprehended only by the mind; if, however,
 as some say, true opinion differs in no respect from mind, then
 everything that we perceive through the body is to be regarded as most
 real and certain. But we must affirm that to be distinct, for they
 have a distinct origin and are of a different nature; the one is
 implanted in us by instruction, the other by persuasion; the one is
 always accompanied by true reason, the other is without reason; the
 one cannot be overcome by persuasion, but the other can: and lastly,
 every man may be said to share in true opinion, but mind is the
 attribute of the gods and of very few men. Wherefore also we must
 acknowledge that there is one kind of being which is always the
 same, uncreated and indestructible, never receiving anything into
 itself from without, nor itself going out to any other, but
 invisible and imperceptible by any sense, and of which the
 contemplation is granted to intelligence only. And there is another
 nature of the same name with it, and like to it, perceived by sense,
 created, always in motion, becoming in place and again vanishing out
 of place, which is apprehended by opinion and sense. And there is a
 third nature, which is space, and is eternal, and admits not of
 destruction and provides a home for all created things, and is
 apprehended without the help of sense, by a kind of spurious reason,
 and is hardly real; which we beholding as in a dream, say of all
 existence that it must of necessity be in some place and occupy a
 space, but that what is neither in heaven nor in earth has no
 existence. Of these and other things of the same kind, relating to the
 true and waking reality of nature, we have only this dreamlike
 sense, and we are unable to cast off sleep and determine the truth
 about them. For an image, since the reality, after which it is
 modelled, does not belong to it, and it exists ever as the fleeting
 shadow of some other, must be inferred to be in another [i.e. in space
 ], grasping existence in some way or other, or it could not be at all.
 But true and exact reason, vindicating the nature of true being,
 maintains that while two things [i.e. the image and space] are
 different they cannot exist one of them in the other and so be one and
 also two at the same time.
   Thus have I concisely given the result of my thoughts; and my
 verdict is that being and space and generation, these three, existed
 in their three ways before the heaven; and that the nurse of
 generation, moistened by water and inflamed by fire, and receiving the
 forms of earth and air, and experiencing all the affections which
 accompany these, presented a strange variety of appearances; and being
 full of powers which were neither similar nor equally balanced, was
 never in any part in a state of equipoise, but swaying unevenly hither
 and thither, was shaken by them, and by its motion again shook them;
 and the elements when moved were separated and carried continually,
 some one way, some another; as, when rain is shaken and winnowed by
 fans and other instruments used in the threshing of corn, the close
 and heavy particles are borne away and settle in one direction, and
 the loose and light particles in another. In this manner, the four
 kinds or elements were then shaken by the receiving vessel, which,
 moving like a winnowing machine, scattered far away from one another
 the elements most unlike, and forced the most similar elements into
 dose contact. Wherefore also the various elements had different places
 before they were arranged so as to form the universe. At first, they
 were all without reason and measure. But when the world began to get
 into order, fire and water and earth and air had only certain faint
 traces of themselves, and were altogether such as everything might
 be expected to be in the absence of God; this, I say, was their nature
 at that time, and God fashioned them by form and number. Let it be
 consistently maintained by us in all that we say that God made them as
 far as possible the fairest and best, out of things which were not
 fair and good. And now I will endeavour to show you the disposition
 and generation of them by an unaccustomed argument, which am compelled
 to use; but I believe that you will be able to follow me, for your
 education has made you familiar with the methods of science.
   In the first place, then, as is evident to all, fire and earth and
 water and air are bodies. And every sort of body possesses solidity,
 and every solid must necessarily be contained in planes; and every
 plane rectilinear figure is composed of triangles; and all triangles
 are originally of two kinds, both of which are made up of one right
 and two acute angles; one of them has at either end of the base the
 half of a divided right angle, having equal sides, while in the
 other the right angle is divided into unequal parts, having unequal
 sides. These, then, proceeding by a combination of probability with
 demonstration, we assume to be the original elements of fire and the
 other bodies; but the principles which are prior to these God only
 knows, and he of men who is the friend God. And next we have to
 determine what are the four most beautiful bodies which are unlike one
 another, and of which some are capable of resolution into one another;
 for having discovered thus much, we shall know the true origin of
 earth and fire and of the proportionate and intermediate elements. And
 then we shall not be willing to allow that there are any distinct
 kinds of visible bodies fairer than these. Wherefore we must endeavour
 to construct the four forms of bodies which excel in beauty, and
 then we shall be able to say that we have sufficiently apprehended
 their nature. Now of the two triangles, the isosceles has one form
 only; the scalene or unequal-sided has an infinite number. Of the
 infinite forms we must select the most beautiful, if we are to proceed
 in due order, and any one who can point out a more beautiful form than
 ours for the construction of these bodies, shall carry off the palm,
 not as an enemy, but as a friend. Now, the one which we maintain to be
 the most beautiful of all the many triangles (and we need not speak of
 the others) is that of which the double forms a third triangle which
 is equilateral; the reason of this would be long to tell; he who
 disproves what we are saying, and shows that we are mistaken, may
 claim a friendly victory. Then let us choose two triangles, out of
 which fire and the other elements have been constructed, one
 isosceles, the other having the square of the longer side equal to
 three times the square of the lesser side.
   Now is the time to explain what was before obscurely said: there was
 an error in imagining that all the four elements might be generated by
 and into one another; this, I say, was an erroneous supposition, for
 there are generated from the triangles which we have selected four
 kinds-three from the one which has the sides unequal; the fourth alone
 is framed out of the isosceles triangle. Hence they cannot all be
 resolved into one another, a great number of small bodies being
 combined into a few large ones, or the converse. But three of them can
 be thus resolved and compounded, for they all spring from one, and
 when the greater bodies are broken up, many small bodies will spring
 up out of them and take their own proper figures; or, again, when many
 small bodies are dissolved into their triangles, if they become one,
 they will form one large mass of another kind. So much for their
 passage into one another. I have now to speak of their several
 kinds, and show out of what combinations of numbers each of them was
 formed. The first will be the simplest and smallest construction,
 and its element is that triangle which has its hypotenuse twice the
 lesser side. When two such triangles are joined at the diagonal, and
 this is repeated three times, and the triangles rest their diagonals
 and shorter sides on the same point as a centre, a single
 equilateral triangle is formed out of six triangles; and four
 equilateral triangles, if put together, make out of every three
 plane angles one solid angle, being that which is nearest to the
 most obtuse of plane angles; and out of the combination of these
 four angles arises the first solid form which distributes into equal
 and similar parts the whole circle in which it is inscribed. The
 second species of solid is formed out of the same triangles, which
 unite as eight equilateral triangles and form one solid angle out of
 four plane angles, and out of six such angles the second body is
 completed. And the third body is made up of 120 triangular elements,
 forming twelve solid angles, each of them included in five plane
 equilateral triangles, having altogether twenty bases, each of which
 is an equilateral triangle. The one element [that is, the triangle
 which has its hypotenuse twice the lesser side] having generated these
 figures, generated no more; but the isosceles triangle produced the
 fourth elementary figure, which is compounded of four such
 triangles, joining their right angles in a centre, and forming one
 equilateral quadrangle. Six of these united form eight solid angles,
 each of which is made by the combination of three plane right
 angles; the figure of the body thus composed is a cube, having six
 plane quadrangular equilateral bases. There was yet a fifth
 combination which God used in the delineation of the universe.
   Now, he who, duly reflecting on all this, enquires whether the
 worlds are to be regarded as indefinite or definite in number, will be
 of opinion that the notion of their indefiniteness is characteristic
 of a sadly indefinite and ignorant mind. He, however, who raises the
 question whether they are to be truly regarded as one or five, takes
 up a more reasonable position. Arguing from probabilities, I am of
 opinion that they are one; another, regarding the question from
 another point of view, will be of another mind. But, leaving this
 enquiry, let us proceed to distribute the elementary forms, which have
 now been created in idea, among the four elements.
   To earth, then, let us assign the cubical form; for earth is the
 most immoveable of the four and the most plastic of all bodies, and
 that which has the most stable bases must of necessity be of such a
 nature. Now, of the triangles which we assumed at first, that which
 has two equal sides is by nature more firmly based than that which has
 unequal sides; and of the compound figures which are formed out of
 either, the plane equilateral quadrangle has necessarily, a more
 stable basis than the equilateral triangle, both in the whole and in
 the parts. Wherefore, in assigning this figure to earth, we adhere
 to probability; and to water we assign that one of the remaining forms
 which is the least moveable; and the most moveable of them to fire;
 and to air that which is intermediate. Also we assign the smallest
 body to fire, and the greatest to water, and the intermediate in
 size to air; and, again, the acutest body to fire, and the next in
 acuteness to, air, and the third to water. Of all these elements, that
 which has the fewest bases must necessarily be the most moveable,
 for it must be the acutest and most penetrating in every way, and also
 the lightest as being composed of the smallest number of similar
 particles: and the second body has similar properties in a second
 degree, and the third body in the third degree. Let it be agreed,
 then, both according to strict reason and according to probability,
 that the pyramid is the solid which is the original element and seed
 of fire; and let us assign the element which was next in the order
 of generation to air, and the third to water. We must imagine all
 these to be so small that no single particle of any of the four
 kinds is seen by us on account of their smallness: but when many of
 them are collected together their aggregates are seen. And the
 ratios of their numbers, motions, and other properties, everywhere
 God, as far as necessity allowed or gave consent, has exactly
 perfected, and harmonised in due proportion.
   From all that we have just been saying about the elements or
 kinds, the most probable conclusion is as follows:-earth, when meeting
 with fire and dissolved by its sharpness, whether the dissolution take
 place in the fire itself or perhaps in some mass of air or water, is
 borne hither and thither, until its parts, meeting together and
 mutually harmonising, again become earth; for they can never take
 any other form. But water, when divided by fire or by air, on
 reforming, may become one part fire and two parts air; and a single
 volume of air divided becomes two of fire. Again, when a small body of
 fire is contained in a larger body of air or water or earth, and
 both are moving, and the fire struggling is overcome and broken up,
 then two volumes of fire form one volume of air; and when air is
 overcome and cut up into small pieces, two and a half parts of air are
 condensed into one part of water. Let us consider the matter in
 another way. When one of the other elements is fastened upon by
 fire, and is cut by the sharpness of its angles and sides, it
 coalesces with the fire, and then ceases to be cut by them any longer.
 For no element which is one and the same with itself can be changed by
 or change another of the same kind and in the same state. But so
 long as in the process of transition the weaker is fighting against
 the stronger, the dissolution continues. Again, when a few small
 particles, enclosed in many larger ones, are in process of
 decomposition and extinction, they only cease from their tendency to
 extinction when they consent to pass into the conquering nature, and
 fire becomes air and air water. But if bodies of another kind go and
 attack them [i.e. the small particles], the latter continue to be
 dissolved until, being completely forced back and dispersed, they make
 their escape to their own kindred, or else, being overcome and
 assimilated to the conquering power, they remain where they are and
 dwell with their victors, and from being many become one. And owing to
 these affections, all things are changing their place, for by the
 motion of the receiving vessel the bulk of each class is distributed
 into its proper place; but those things which become unlike themselves
 and like other things, are hurried by the shaking into the place of
 the things to which they grow like.
   Now all unmixed and primary bodies are produced by such causes as
 these. As to the subordinate species which are included in the greater
 kinds, they are to be attributed to the varieties in the structure
 of the two original triangles. For either structure did not originally
 produce the triangle of one size only, but some larger and some
 smaller, and there are as many sizes as there are species of the
 four elements. Hence when they are mingled with themselves and with
 one another there is an endless variety of them, which those who would
 arrive at the probable truth of nature ought duly to consider.
   Unless a person comes to an understanding about the nature and
 conditions of rest and motion, he will meet with many difficulties
 in the discussion which follows. Something has been said of this
 matter already, and something more remains to be said, which is,
 that motion never exists in what is uniform. For to conceive that
 anything can be moved without a mover is hard or indeed impossible,
 and equally impossible to conceive that there can be a mover unless
 there be something which can be moved-motion cannot exist where either
 of these are wanting, and for these to be uniform is impossible;
 wherefore we must assign rest to uniformity and motion to the want
 of uniformity. Now inequality is the cause of the nature which is
 wanting in uniformity; and of this we have already described the
 origin. But there still remains the further point-why things when
 divided after their kinds do not cease to pass through one another and
 to change their place-which we will now proceed to explain. In the
 revolution of the universe are comprehended all the four elements, and
 this being circular and having a tendency to come together, compresses
 everything and will not allow any place to be left void. Wherefore,
 also, fire above all things penetrates everywhere, and air next, as
 being next in rarity of the elements; and the two other elements in
 like manner penetrate according to their degrees of rarity. For
 those things which are composed of the largest particles have the
 largest void left in their compositions, and those which are
 composed of the smallest particles have the least. And the contraction
 caused by the compression thrusts the smaller particles into the
 interstices of the larger. And thus, when the small parts are placed
 side by side with the larger, and the lesser divide the greater and
 the greater unite the lesser, all the elements are borne up and down
 and hither and thither towards their own places; for the change in the
 size of each changes its position in space. And these causes
 generate an inequality which is always maintained, and is
 continually creating a perpetual motion of the elements in all time.
   In the next place we have to consider that there are divers kinds of
 fire. There are, for example, first, flame; and secondly, those
 emanations of flame which do not burn but only give light to the eyes;
 thirdly, the remains of fire, which are seen in red-hot embers after
 the flame has been extinguished. There are similar differences in
 the air; of which the brightest part is called the aether, and the
 most turbid sort mist and darkness; and there are various other
 nameless kinds which arise from the inequality of the triangles.
 Water, again, admits in the first place of a division into two
 kinds; the one liquid and the other fusile. The liquid kind is
 composed of the small and unequal particles of water; and moves itself
 and is moved by other bodies owing to the want of uniformity and the
 shape of its particles; whereas the fusile kind, being formed of large
 and uniform particles, is more stable than the other, and is heavy and
 compact by reason of its uniformity. But when fire gets in and
 dissolves the particles and destroys the uniformity, it has greater
 mobility, and becoming fluid is thrust forth by the neighbouring air
 and spreads upon the earth; and this dissolution of the solid masses
 is called melting, and their spreading out upon the earth flowing.
 Again, when the fire goes out of the fusile substance, it does not
 pass into vacuum, but into the neighbouring air; and the air which
 is displaced forces together the liquid and still moveable mass into
 the place which was occupied by the fire, and unites it with itself.
 Thus compressed the mass resumes its equability, and is again at unity
 with itself, because the fire which was the author of the inequality
 has retreated; and this departure of the fire is called cooling, and
 the coming together which follows upon it is termed congealment. Of
 all the kinds termed fusile, that which is the densest and is formed
 out of the finest and most uniform parts is that most precious
 possession called gold, which is hardened by filtration through
 rock; this is unique in kind, and has both a glittering and a yellow
 colour. A shoot of gold, which is so dense as to be very hard, and
 takes a black colour, is termed adamant. There is also another kind
 which has parts nearly like gold, and of which there are several
 species; it is denser than gold, and it contains a small and fine
 portion of earth, and is therefore harder, yet also lighter because of
 the great interstices which it has within itself; and this
 substance, which is one of the bright and denser kinds of water,
 when solidified is called copper. There is an alloy of earth mingled
 with it, which, when the two parts grow old and are disunited, shows
 itself separately and is called rust. The remaining phenomena of the
 same kind there will be no difficulty in reasoning out by the method
 of probabilities. A man may sometimes set aside meditations about
 eternal things, and for recreation turn to consider the truths of
 generation which are probable only; he will thus gain a pleasure not
 to be repented of, and secure for himself while he lives a wise and
 moderate pastime. Let us grant ourselves this indulgence, and go
 through the probabilities relating to the same subjects which follow
 next in order.
   Water which is mingled with fire, so much as is fine and liquid
 (being so called by reason of its motion and the way in which it rolls
 along the ground), and soft, because its bases give way are less
 stable than those of earth, when separated from fire and air and
 isolated, becomes more uniform, and by their retirement is
 compressed into itself; and if the condensation be very great, the
 water above the earth becomes hail, but on the earth, ice; and that
 which is congealed in a less degree and is only half solid, when above
 the earth is called snow, and when upon the earth, and condensed
 from dew, hoarfrost. Then, again, there are the numerous kinds of
 water which have been mingled with one another, and are distilled
 through plants which grow in the earth; and this whole class is called
 by the name of juices or saps. The unequal admixture of these fluids
 creates a variety of species; most of them are nameless, but four
 which are of a fiery nature are clearly distinguished and have
 names. First there is wine, which warms the soul as well as the
 body: secondly, there is the oily nature, which is smooth and
 divides the visual ray, and for this reason is bright and shining
 and of a glistening appearance, including pitch, the juice of the
 castor berry, oil itself, and other things of a like kind: thirdly,
 there is the class of substances which expand the contracted parts
 of the mouth, until they return to their natural state, and by
 reason of this property create sweetness;-these are included under the
 general name of honey: and, lastly, there is a frothy nature, which
 differs from all juices, having a burning quality which dissolves
 the flesh; it is called opos (a vegetable acid).
   As to the kinds of earth, that which is filtered through water
 passes into stone in the following manner:-The water which mixes
 with the earth and is broken up in the process changes into air, and
 taking this form mounts into its own place. But as there is no
 surrounding vacuum it thrusts away the neighbouring air, and this
 being rendered heavy, and, when it is displaced, having been poured
 around the mass of earth, forcibly compresses it and drives it into
 the vacant space whence the new air had come up; and the earth when
 compressed by the air into an indissoluble union with water becomes
 rock. The fairer sort is that which is made up of equal and similar
 parts and is transparent; that which has the opposite qualities is
 inferior. But when all the watery part is suddenly drawn out by
 fire, a more brittle substance is formed, to which we give the name of
 pottery. Sometimes also moisture may remain, and the earth which has
 been fused by fire becomes, when cool, a certain stone of a black
 colour. A like separation of the water which had been copiously
 mingled with them may occur in two substances composed of finer
 particles of earth and of a briny nature; out of either of them a half
 solid body is then formed, soluble in water-the one, soda, which is
 used for purging away oil and earth, and other, salt, which harmonizes
 so well in combinations pleasing to the palate, and is, as the law
 testifies, a substance dear to the gods. The compounds of earth and
 water are not soluble by water, but by fire only, and for this
 reason:-Neither fire nor air melt masses of earth; for their
 particles, being smaller than the interstices in its structure, have
 plenty of room to move without forcing their way, and so they leave
 the earth unmelted and undissolved; but particles of water, which
 are larger, force a passage, and dissolve and melt the earth.
 Wherefore earth when not consolidated by force is dissolved by water
 only; when consolidated, by nothing but fire; for this is the only
 body which can find an entrance. The cohesion of water again, when
 very strong, is dissolved by fire only-when weaker, then either by air
 or fire-the former entering the interstices, and the latter
 penetrating even the triangles. But nothing can dissolve air, when
 strongly condensed, which does not reach the elements or triangles; or
 if not strongly condensed, then only fire can dissolve it. As to
 bodies composed of earth and water, while the water occupies the
 vacant interstices of the earth in them which are compressed by force,
 the particles of water which approach them from without, finding no
 entrance, flow around the entire mass and leave it undissolved; but
 the particles of fire, entering into the interstices of the water,
 do to the water what water does to earth and fire to air, and are
 the sole causes of the compound body of earth and water liquefying and
 becoming fluid. Now these bodies are of two kinds; some of them,
 such as glass and the fusible sort of stones, have less water than
 they have earth; on the other hand, substances of the nature of wax
 and incense have more of water entering into their composition.
   I have thus shown the various classes of bodies as they are
 diversified by their forms and combinations and changes into one
 another, and now I must endeavour to set forth their affections and
 the causes of them. In the first place, the bodies which I have been
 describing are necessarily objects of sense. But we have not yet
 considered the origin of flesh, or what belongs to flesh, or of that
 part of the soul which is mortal. And these things cannot be
 adequately explained without also explaining the affections which
 are concerned with sensation, nor the latter without the former: and
 yet to explain them together is hardly possible; for which reason we
 must assume first one or the other and afterwards examine the nature
 of our hypothesis. In order, then, that the affections may follow
 regularly after the elements, let us presuppose the existence of
 body and soul.
   First, let us enquire what we mean by saying that fire is hot; and
 about this we may reason from the dividing or cutting power which it
 exercises on our bodies. We all of us feel that fire is sharp; and
 we may further consider the fineness of the sides, and the sharpness
 of the angles, and the smallness of the particles, and the swiftness
 of the motion-all this makes the action of fire violent and sharp,
 so that it cuts whatever it meets. And we must not forget that the
 original figure of fire [i.e. the pyramid], more than any other
 form, has a dividing power which cuts our bodies into small pieces
 (Kepmatizei), and thus naturally produces that affection which we call
 heat; and hence the origin of the name (thepmos, Kepma). Now, the
 opposite of this is sufficiently manifest; nevertheless we will not
 fail to describe it. For the larger particles of moisture which
 surround the body, entering in and driving out the lesser, but not
 being able to take their places, compress the moist principle in us;
 and this from being unequal and disturbed, is forced by them into a
 state of rest, which is due to equability and compression. But
 things which are contracted contrary to nature are by nature at war,
 and force themselves apart; and to this war and convulsion the name of
 shivering and trembling is given; and the whole affection and the
 cause of the affection are both termed cold. That is called hard to
 which our flesh yields, and soft which yields to our flesh; and things
 are also termed hard and soft relatively to one another. That which
 yields has a small base; but that which rests on quadrangular bases is
 firmly posed and belongs to the class which offers the greatest
 resistance; so too does that which is the most compact and therefore
 most repellent. The nature of the light and the heavy will be best
 understood when examined in connexion with our notions of above and
 below; for it is quite a mistake to suppose that the universe is
 parted into two regions, separate from and opposite to each other, the
 one a lower to which all things tend which have any bulk, and an upper
 to which things only ascend against their will. For as the universe is
 in the form of a sphere, all the extremities, being equidistant from
 the centre, are equally extremities, and the centre, which is
 equidistant from them, is equally to be regarded as the opposite of
 them all. Such being the nature of the world, when a person says
 that any of these points is above or below, may he not be justly
 charged with using an improper expression? For the centre of the world
 cannot be rightly called either above or below, but is the centre
 and nothing else; and the circumference is not the centre, and has
 in no one part of itself a different relation to the centre from
 what it has in any of the opposite parts. Indeed, when it is in
 every direction similar, how can one rightly give to it names which
 imply opposition? For if there were any solid body in equipoise at the
 centre of the universe, there would be nothing to draw it to this
 extreme rather than to that, for they are all perfectly similar; and
 if a person were to go round the world in a circle, he would often,
 when standing at the antipodes of his former position, speak of the
 same point as above and below; for, as I was saying just now, to speak
 of the whole which is in the form of a globe as having one part
 above and another below is not like a sensible man.
   The reason why these names are used, and the circumstances under
 which they are ordinarily applied by us to the division of the
 heavens, may be elucidated by the following supposition:-if a person
 were to stand in that part of the universe which is the appointed
 place of fire, and where there is the great mass of fire to which
 fiery bodies gather-if, I say, he were to ascend thither, and,
 having the power to do this, were to abstract particles of fire and
 put them in scales and weigh them, and then, raising the balance, were
 to draw the fire by force towards the uncongenial element of the
 air, it would be very evident that he could compel the smaller mass
 more readily than the larger; for when two things are simultaneously
 raised by one and the same power, the smaller body must necessarily
 yield to the superior power with less reluctance than the larger;
 and the larger body is called heavy and said to tend downwards, and
 the smaller body is called light and said to tend upwards. And we
 may detect ourselves who are upon the earth doing precisely the same
 thing. For we of separate earthy natures, and sometimes earth
 itself, and draw them into the uncongenial element of air by force and
 contrary to nature, both clinging to their kindred elements. But
 that which is smaller yields to the impulse given by us towards the
 dissimilar element more easily than the larger; and so we call the
 former light, and the place towards which it is impelled we call
 above, and the contrary state and place we call heavy and below
 respectively. Now the relations of these must necessarily vary,
 because the principal masses of the different elements hold opposite
 positions; for that which is light, heavy, below or above in one place
 will be found to be and become contrary and transverse and every way
 diverse in relation to that which is light, heavy, below or above in
 an opposite place. And about all of them this has to be
 considered:-that the tendency of each towards its kindred element
 makes the body which is moved heavy, and the place towards which the
 motion tends below, but things which have an opposite tendency we call
 by an opposite name. Such are the causes which we assign to these
 phenomena. As to the smooth and the rough, any one who sees them can
 explain the reason of them to another. For roughness is hardness
 mingled with irregularity, and smoothness is produced by the joint
 effect of uniformity and density.
   The most important of the affections which concern the whole body
 remains to be considered-that is, the cause of pleasure and pain in
 the perceptions of which I have been speaking, and in all other things
 which are perceived by sense through the parts of the body, and have
 both pains and pleasures attendant on them. Let us imagine the
 causes of every affection, whether of sense or not, to be of the
 following nature, remembering that we have already distinguished
 between the nature which is easy and which is hard to move; for this
 is the direction in which we must hunt the prey which we mean to take.
 A body which is of a nature to be easily moved, on receiving an
 impression however slight, spreads abroad the motion in a circle,
 the parts communicating with each other, until at last, reaching the
 principle of mind, they announce the quality of the agent. But a
 body of the opposite kind, being immobile, and not extending to the
 surrounding region, merely receives the impression, and does not
 stir any of the neighbouring parts; and since the parts do not
 distribute the original impression to other parts, it has no effect of
 motion on the whole animal, and therefore produces no effect on the
 patient. This is true of the bones and hair and other more earthy
 parts of the human body; whereas what was said above relates mainly to
 sight and hearing, because they have in them the greatest amount of
 fire and air. Now we must conceive of pleasure and pain in this way.
 An impression produced in us contrary to nature and violent, if
 sudden, is painful; and, again, the sudden return to nature is
 pleasant; but a gentle and gradual return is imperceptible and vice
 versa. On the other hand the impression of sense which is most
 easily produced is most readily felt, but is not accompanied by
 Pleasure or pain; such, for example, are the affections of the
 sight, which, as we said above, is a body naturally uniting with our
 body in the day-time; for cuttings and burnings and other
 affections which happen to the sight do not give pain, nor is there
 pleasure when the sight returns to its natural state; but the
 sensations are dearest and strongest according to the manner in
 which the eye is affected by the object, and itself strikes and
 touches it; there is no violence either in the contraction or dilation
 of the eye. But bodies formed of larger particles yield to the agent
 only with a struggle; and then they impart their motions to the
 whole and cause pleasure and pain-pain when alienated from their
 natural conditions, and pleasure when restored to them. Things which
 experience gradual withdrawings and emptyings of their nature, and
 great and sudden replenishments, fail to perceive the emptying, but
 are sensible of the replenishment; and so they occasion no pain, but
 the greatest pleasure, to the mortal part of the soul, as is
 manifest in the case of perfumes. But things which are changed all of
 a sudden, and only gradually and with difficulty return to their own
 nature, have effects in every way opposite to the former, as is
 evident in the case of burnings and cuttings of the body.
   Thus have we discussed the general affections of the whole body, and
 the names of the agents which produce them. And now I will endeavour
 to speak of the affections of particular parts, and the causes and
 agents of them, as far as I am able. In the first place let us set
 forth what was omitted when we were speaking of juices, concerning the
 affections peculiar to the tongue. These too, like most of the other
 affections, appear to be caused by certain contractions and dilations,
 but they have besides more of roughness and smoothness than is found
 in other affections; for whenever earthy particles enter into the
 small veins which are the testing of the tongue, reaching to the
 heart, and fall upon the moist, delicate portions of flesh-when, as
 they are dissolved, they contract and dry up the little veins, they
 are astringent if they are rougher, but if not so rough, then only
 harsh. Those of them which are of an abstergent nature, and purge
 the whole surface of the tongue, if they do it in excess, and so
 encroach as to consume some part of the flesh itself, like potash
 and soda, are all termed bitter. But the particles which are deficient
 in the alkaline quality, and which cleanse only moderately, are called
 salt, and having no bitterness or roughness, are regarded as rather
 agreeable than otherwise. Bodies which share in and are made smooth by
 the heat of the mouth, and which are inflamed, and again in turn
 inflame that which heats them, and which are so light that they are
 carried upwards to the sensations of the head, and cut all that
 comes in their way, by reason of these qualities in them, are all
 termed pungent. But when these same particles, refined by
 putrefaction, enter into the narrow veins, and are duly proportioned
 to the particles of earth and air which are there, they set them
 whirling about one another, and while they are in a whirl cause them
 to dash against and enter into one another, and so form hollows
 surrounding the particles that enter-which watery vessels of air
 (for a film of moisture, sometimes earthy, sometimes pure, is spread
 around the air) are hollow spheres of water; and those of them which
 are pure, are transparent, and are called bubbles, while those
 composed of the earthy liquid, which is in a state of general
 agitation and effervescence, are said to boil or ferment-of all
 these affections the cause is termed acid. And there is the opposite
 affection arising from an opposite cause, when the mass of entering
 particles, immersed in the moisture of the mouth, is congenial to
 the tongue, and smooths and oils over the roughness, and relaxes the
 parts which are unnaturally contracted, and contracts the parts
 which are relaxed, and disposes them all according to their
 nature-that sort of remedy of violent affections is pleasant and
 agreeable to every man, and has the name sweet. But enough of this.
   The faculty of smell does not admit of differences of kind; for
 all smells are of a half formed nature, and no element is so
 proportioned as to have any smell. The veins about the nose are too
 narrow to admit earth and water, and too wide to detain fire and
 air; and for this reason no one ever perceives the smell of any of
 them; but smells always proceed from bodies that are damp, or
 putrefying, or liquefying, or evaporating, and are perceptible only in
 the intermediate state, when water is changing into air and air into
 water; and all of them are either vapor or mist. That which is passing
 out of air into water is mist, and that which is passing from water
 into air is vapour; and hence all smells are thinner than water and
 thicker than air. The proof of this is, that when there is any
 obstruction to the respiration, and a man draws in his breath by
 force, then no smell filters through, but the air without the smell
 alone penetrates. Wherefore the varieties of smell have no name, and
 they have not many, or definite and simple kinds; but they are
 distinguished only painful and pleasant, the one sort irritating and
 disturbing the whole cavity which is situated between the head and the
 navel, the other having a soothing influence, and restoring this
 same region to an agreeable and natural condition.
   In considering the third kind of sense, hearing, we must speak of
 the causes in which it originates. We may in general assume sound to
 be a blow which passes through the ears, and is transmitted by means
 of the air, the brain, and the blood, to the soul, and that hearing is
 the vibration of this blow, which begins in the head and ends in the
 region of the liver. The sound which moves swiftly is acute, and the
 sound which moves slowly is grave, and that which is regular is
 equable and smooth, and the reverse is harsh. A great body of sound is
 loud, and a small body of sound the reverse. Respecting the
 harmonies of sound I must hereafter speak.
   There is a fourth class of sensible things, having many intricate
 varieties, which must now be distinguished. They are called by the
 general name of colours, and are a flame which emanates from every
 sort of body, and has particles corresponding to the sense of sight. I
 have spoken already, in what has preceded, of the causes which
 generate sight, and in this place it will be natural and suitable to
 give a rational theory of colours.
   Of the particles coming from other bodies which fall upon the sight,
 some are smaller and some are larger, and some are equal to the
 parts of the sight itself. Those which are equal are imperceptible,
 and we call them transparent. The larger produce contraction, the
 smaller dilation, in the sight, exercising a power akin to that of hot
 and cold bodies on the flesh, or of astringent bodies on the tongue,
 or of those heating bodies which we termed pungent. White and black
 are similar effects of contraction and dilation in another sphere, and
 for this reason have a different appearance. Wherefore, we ought to
 term white that which dilates the visual ray, and the opposite of this
 is black. There is also a swifter motion of a different sort of fire
 which strikes and dilates the ray of sight until it reaches the
 eyes, forcing a way through their passages and melting them, and
 eliciting from them a union of fire and water which we call tears,
 being itself an opposite fire which comes to them from an opposite
 direction-the inner fire flashes forth like lightning, and the outer
 finds a way in and is extinguished in the moisture, and all sorts of
 colours are generated by the mixture. This affection is termed
 dazzling, and the object which produces it is called bright and
 flashing. There is another sort of fire which is intermediate, and
 which reaches and mingles with the moisture of the eye without
 flashing; and in this, the fire mingling with the ray of the moisture,
 produces a colour like blood, to which we give the name of red. A
 bright hue mingled with red and white gives the colour called
 auburn. The law of proportion, however, according to which the several
 colours are formed, even if a man knew he would be foolish in telling,
 for he could not give any necessary reason, nor indeed any tolerable
 or probable explanation of them. Again, red, when mingled with black
 and white, becomes purple, but it becomes umber when the colours are
 burnt as well as mingled and the black is more thoroughly mixed with
 them. Flame colour is produced by a union of auburn and dun, and dun
 by an admixture of black and white; pale yellow, by an admixture of
 white and auburn. White and bright meeting, and falling upon a full
 black, become dark blue, and when dark blue mingles with white, a
 light blue colour is formed, as flame-colour with black makes leek
 green. There will be no difficulty in seeing how and by what
 mixtures the colours derived from these are made according to the
 rules of probability. He, however, who should attempt to verify all
 this by experiment, would forget the difference of the human and
 divine nature. For God only has the knowledge and also the power which
 are able to combine many things into one and again resolve the one
 into many. But no man either is or ever will be able to accomplish
 either the one or the other operation.
   These are the elements, thus of necessity then subsisting, which the
 creator of the fairest and best of created things associated with
 himself, when he made the self-sufficing and most perfect God, using
 the necessary causes as his ministers in the accomplishment of his
 work, but himself contriving the good in all his creations.
 Wherefore we may distinguish two sorts of causes, the one divine and
 the other necessary, and may seek for the divine in all things, as far
 as our nature admits, with a view to the blessed life; but the
 necessary kind only for the sake of the divine, considering that
 without them and when isolated from them, these higher things for
 which we look cannot be apprehended or received or in any way shared
 by us.
   Seeing, then, that we have now prepared for our use the various
 classes of causes which are the material out of which the remainder of
 our discourse must be woven, just as wood is the material of the
 carpenter, let us revert in a few words to the point at which we
 began, and then endeavour to add on a suitable ending to the beginning
 of our tale.
   As I said at first, when all things were in disorder God created
 in each thing in relation to itself, and in all things in relation
 to each other, all the measures and harmonies which they could
 possibly receive. For in those days nothing had any proportion
 except by accident; nor did any of the things which now have names
 deserve to be named at all-as, for example, fire, water, and the
 rest of the elements. All these the creator first set in order, and
 out of them he constructed the universe, which was a single animal
 comprehending in itself all other animals, mortal and immortal. Now of
 the divine, he himself was the creator, but the creation of the mortal
 he committed to his offspring. And they, imitating him, received
 from him the immortal principle of the soul; and around this they
 proceeded to fashion a mortal body, and. made it to be the vehicle
 of the so and constructed within the body a soul of another nature
 which was mortal, subject to terrible and irresistible
 affections-first of all, pleasure, the greatest incitement to evil;
 then, pain, which deters from good; also rashness and fear, two
 foolish counsellors, anger hard to be appeased, and hope easily led
 astray-these they mingled with irrational sense and with all-daring
 love according to necessary laws, and so framed man. Wherefore,
 fearing to pollute the divine any more than was absolutely
 unavoidable, they gave to the mortal nature a separate habitation in
 another part of the body, placing the neck between them to be the
 isthmus and boundary, which they constructed between the head and
 breast, to keep them apart. And in the breast, and in what is termed
 the thorax, they encased the mortal soul; and as the one part of
 this was superior and the other inferior they divided the cavity of
 the thorax into two parts, as the women's and men's apartments are
 divided in houses, and placed the midriff to be a wall of partition
 between them. That part of the inferior soul which is endowed with
 courage and passion and loves contention they settled nearer the head,
 midway between the midriff and the neck, in order that it might be
 under the rule of reason and might join with it in controlling and
 restraining the desires when they are no longer willing of their own
 accord to obey the word of command issuing from the citadel.
   The heart, the knot of the veins and the fountain of the blood which
 races through all the limbs was set in the place of guard, that when
 the might of passion was roused by reason making proclamation of any
 wrong assailing them from without or being perpetrated by the
 desires within, quickly the whole power of feeling in the body,
 perceiving these commands and threats, might obey and follow through
 every turn and alley, and thus allow the principle of the best to have
 the command in all of them. But the gods, foreknowing that the
 palpitation of the heart in the expectation of danger and the swelling
 and excitement of passion was caused by fire, formed and implanted
 as a supporter to the heart the lung, which was, in the first place,
 soft and bloodless, and also had within hollows like the pores of a
 sponge, in order that by receiving the breath and the drink, it
 might give coolness and the power of respiration and alleviate the
 heat. Wherefore they cut the air-channels leading to the lung, and
 placed the lung about the heart as a soft spring, that, when passion
 was rife within, the heart, beating against a yielding body, might
 be cooled and suffer less, and might thus become more ready to join
 with passion in the service of reason.
   The part of the soul which desires meats and drinks and the other
 things of which it has need by reason of the bodily nature, they
 placed between the midriff and the boundary of the navel, contriving
 in all this region a sort of manger for the food of the body; and
 there they bound it down like a wild animal which was chained up
 with man, and must be nourished if man was to exist. They appointed
 this lower creation his place here in order that he might be always
 feeding at the manger, and have his dwelling as far as might be from
 the council-chamber, making as little noise and disturbance as
 possible, and permitting the best part to advise quietly for the
 good of the whole. And knowing that this lower principle in man
 would not comprehend reason, and even if attaining to some degree of
 perception would never naturally care for rational notions, but that
 it would be led away by phantoms and visions night and day-to be a
 remedy for this, God combined with it the liver, and placed it in
 the house of the lower nature, contriving that it should be solid
 and smooth, and bright and sweet, and should also have a bitter
 quality, in order that the power of thought, which proceeds from the
 mind, might be reflected as in a mirror which receives likenesses of
 objects and gives back images of them to the sight; and so might
 strike terror into the desires, when, making use of the bitter part of
 the liver, to which it is akin, it comes threatening and invading, and
 diffusing this bitter element swiftly through the whole liver produces
 colours like bile, and contracting every part makes it wrinkled and
 rough; and twisting out of its right place and contorting the lobe and
 closing and shutting up the vessels and gates, causes pain and
 loathing. And the converse happens when some gentle inspiration of the
 understanding pictures images of an opposite character, and allays the
 bile and bitterness by refusing to stir or touch the nature opposed to
 itself, but by making use of the natural sweetness of the liver,
 corrects all things and makes them to be right and smooth and free,
 and renders the portion of the soul which resides about the liver
 happy and joyful, enabling it to pass the night in peace, and to
 practise divination in sleep, inasmuch as it has no share in mind
 and reason. For the authors of our being, remembering the command of
 their father when he bade them create the human race as good as they
 could, that they might correct our inferior parts and make them to
 attain a measure of truth, placed in the liver the seat of divination.
 And herein is a proof that God has given the art of divination not
 to the wisdom, but to the foolishness of man. No man, when in his
 wits, attains prophetic truth and inspiration; but when he receives
 the inspired word, either his intelligence is enthralled in sleep,
 or he is demented by some distemper or possession. And he who would
 understand what he remembers to have been said, whether in a dream
 or when he was awake, by the prophetic and inspired nature, or would
 determine by reason the meaning of the apparitions which he has
 seen, and what indications they afford to this man or that, of past,
 present or future good and evil, must first recover his wits. But,
 while he continues demented, he cannot judge of the visions which he
 sees or the words which he utters; the ancient saying is very true,
 that "only a man who has his wits can act or judge about himself and
 his own affairs." And for this reason it is customary to appoint
 interpreters to be judges of the true inspiration. Some persons call
 them prophets; they are quite unaware that they are only the
 expositors of dark sayings and visions, and are not to be called
 prophets at all, but only interpreters of prophecy.
   Such is the nature of the liver, which is placed as we have
 described in order that it may give prophetic intimations. During
 the life of each individual these intimations are plainer, but after
 his death the liver becomes blind, and delivers oracles too obscure to
 be intelligible. The neighbouring organ [the spleen] is situated on
 the left-hand side, and is constructed with a view of keeping the
 liver bright and pure-like a napkin, always ready prepared and at hand
 to clean the mirror. And hence, when any impurities arise in the
 region of the liver by reason of disorders of the body, the loose
 nature of the spleen, which is composed of a hollow and bloodless
 tissue, receives them all and dears them away, and when filled with
 the unclean matter, swells and festers, but, again, when the body is
 purged, settles down into the same place as before, and is humbled.
   Concerning the soul, as to which part is mortal and which divine,
 and how and why they are separated, and where located, if God
 acknowledges that we have spoken the truth, then, and then only, can
 we be confident; still, we may venture to assert that what has been
 said by us is probable, and will be rendered more probable by
 investigation. Let us assume thus much.
   The creation of the rest of follows next in order, and this we may
 investigate in a similar manner. And it appears to be very meet that
 the body should be framed on the following principles:-
   The authors of our race were aware that we should be intemperate
 in eating and drinking, and take a good deal more than was necessary
 or proper, by reason of gluttony. In order then that disease might not
 quickly destroy us, and lest our mortal race should perish without
 fulfilling its end-intending to provide against this, the gods made
 what is called the lower belly, to be a receptacle for the superfluous
 meat and drink, and formed the convolution of the bowels, so that
 the food might be prevented from passing quickly through and
 compelling the body to require more food, thus producing insatiable
 gluttony, and making the whole race an enemy to philosophy and
 music, and rebellious against the divinest element within us.
   The bones and flesh, and other similar parts of us, were made as
 follows. The first principle of all of them was the generation of
 the marrow. For the bonds of life which unite the soul with the body
 are made fast there, and they are the root and foundation of the human
 race. The marrow itself is created out of other materials: God took
 such of the primary triangles as were straight and smooth, and were
 adapted by their perfection to produce fire and water, and air and
 earth-these, I say, he separated from their kinds, and mingling them
 in due proportions with one another, made the marrow out of them to be
 a universal seed of the whole race of mankind; and in this seed he
 then planted and enclosed the souls, and in the original
 distribution gave to the marrow as many and various forms as the
 different kinds of souls were hereafter to receive. That which, like a
 field, was to receive the divine seed, he made round every way, and
 called that portion of the marrow, brain, intending that, when an
 animal was perfected, the vessel containing this substance should be
 the head; but that which was intended to contain the remaining and
 mortal part of the soul he distributed into figures at once around and
 elongated, and he called them all by the name "marrow"; and to
 these, as to anchors, fastening the bonds of the whole soul, he
 proceeded to fashion around them the entire framework of our body,
 constructing for the marrow, first of all a complete covering of bone.
   Bone was composed by him in the following manner. Having sifted pure
 and smooth earth he kneaded it and wetted it with marrow, and after
 that he put it into fire and then into water, and once more into
 fire and again into water-in this way by frequent transfers from one
 to the other he made it insoluble by either. Out of this he fashioned,
 as in a lathe, a globe made of bone, which he placed around the brain,
 and in this he left a narrow opening; and around the marrow of the
 neck and back he formed vertebrae which he placed under one another
 like pivots, beginning at the head and extending through the whole
 of the trunk. Thus wishing to preserve the entire seed, he enclosed it
 in a stone-like casing, inserting joints, and using in the formation
 of them the power of the other or diverse as an intermediate nature,
 that they might have motion and flexure. Then again, considering
 that the bone would be too brittle and inflexible, and when heated and
 again cooled would soon mortify and destroy the seed within-having
 this in view, he contrived the sinews and the flesh, that so binding
 all the members together by the sinews, which admitted of being
 stretched and relaxed about the vertebrae, he might thus make the body
 capable of flexion and extension, while the flesh would serve as a
 protection against the summer heat and against the winter cold, and
 also against falls, softly and easily yielding to external bodies,
 like articles made of felt; and containing in itself a warm moisture
 which in summer exudes and makes the surface damp, would impart a
 nature coolness to the whole body; and again in winter by the help
 of this internal warmth would form a very tolerable defence against
 the frost which surrounds it and attacks it from without. He who
 modelled us, considering these things, mixed earth with fire and water
 and blended them; and making a ferment of acid and salt, he mingled it
 with them and formed soft and succulent flesh. As for the sinews, he
 made them of a mixture of bone and unfermented flesh, attempered so as
 to be in a mean, and gave them a yellow colour; wherefore the sinews
 have a firmer and more glutinous nature than flesh, but a softer and
 moister nature than the bones. With these God covered the bones and
 marrow, binding them together by sinews, and then enshrouded them
 all in an upper covering of flesh. The more living and sensitive of
 the bones he enclosed in the thinnest film of flesh, and those which
 had the least life within them in the thickest and most solid flesh.
 So again on the joints of the bones, where reason indicated that no
 more was required, he placed only a thin covering of flesh, that it
 might not interfere with the flexion of our bodies and make them
 unwieldy because difficult to move; and also that it might not, by
 being crowded and pressed and matted together, destroy sensation by
 reason of its hardness, and impair the memory and dull the edge of
 intelligence. Wherefore also the thighs and the shanks and the hips,
 and the bones of the arms and the forearms, and other parts which have
 no joints, and the inner bones, which on account of the rarity of
 the soul in the marrow are destitute of reason-all these are
 abundantly provided with flesh; but such as have mind in them are in
 general less fleshy, except where the creator has made some part
 solely of flesh in order to give sensation-as, for example, the
 tongue. But commonly this is not the case. For the nature which
 comes into being and grows up in us by a law of necessity, does not
 admit of the combination of solid bone and much flesh with acute
 perceptions. More than any other part the framework of the head
 would have had them, if they could have co-existed, and the human
 race, having a strong and fleshy and sinewy head, would have had a
 life twice or many times as long as it now has, and also more
 healthy and free from pain.
   But our creators, considering whether they should make a
 longer-lived race which was worse, or a shorter-lived race which was
 better, came to the conclusion that every one ought to prefer a
 shorter span of life, which was better, to a longer one, which was
 worse; and therefore they covered the head with thin bone, but not
 with flesh and sinews, since it had no joints; and thus the head was
 added, having more wisdom and sensation than the rest of the body, but
 also being in every man far weaker. For these reasons and after this
 manner God placed the sinews at the extremity of the head, in a circle
 round the neck, and glued them together by the principle of likeness
 and fastened the extremities of the jawbones to them below the face,
 and the other sinews he dispersed throughout the body, fastening
 limb to limb. The framers of us framed the mouth, as now arranged,
 having teeth and tongue and lips, with a view to the necessary and the
 good, contriving the way in for necessary purposes, the way out for
 the best purposes; for that is necessary which enters in and gives
 food to the body; but the river of speech, which flows out of a man
 and ministers to the intelligence, is the fairest and noblest of all
 streams. Still the head could neither be left a bare frame of bones,
 on account of the extremes of heat and cold in the different
 seasons, nor yet be allowed to be wholly covered, and so become dull
 and senseless by reason of an overgrowth of flesh. The fleshy nature
 was not therefore wholly dried up, but a large sort of peel was parted
 off and remained over, which is now called the skin. This met and grew
 by the help of the cerebral moisture, and became the circular
 envelopment of the head. And the moisture, rising up under the
 sutures, watered and closed in the skin upon the crown, forming a sort
 of knot. The diversity of the sutures was caused by the power of the
 courses of the soul and of the food, and the more these struggled
 against one another the more numerous they became, and fewer if the
 struggle were less violent. This skin the divine power pierced all
 round with fire, and out of the punctures which were thus made the
 moisture issued forth, and the liquid and heat which was pure came
 away, and a mixed part which was composed of the same material as
 the skin, and had a fineness equal to the punctures, was borne up by
 its own impulse and extended far outside the head, but being too
 slow to escape, was thrust back by the external air, and rolled up
 underneath the skin, where it took root. Thus the hair sprang up in
 the skin, being akin to it because it is like threads of leather,
 but rendered harder and closer through the pressure of the cold, by
 which each hair, while in process of separation from the skin, is
 compressed and cooled. Wherefore the creator formed the head hairy,
 making use of the causes which I have mentioned, and reflecting also
 that instead of flesh the brain needed the hair to be a light covering
 or guard, which would give shade in summer and shelter in winter,
 and at the same time would not impede our quickness of perception.
 From the combination of sinew, skin, and bone, in the structure of the
 finger, there arises a triple compound, which, when dried up, takes
 the form of one hard skin partaking of all three natures, and was
 fabricated by these second causes, but designed by mind which is the
 principal cause with an eye to the future. For our creators well
 knew that women and other animals would some day be framed out of men,
 and they further knew that many animals would require the use of nails
 for many purposes; wherefore they fashioned in men at their first
 creation the rudiments of nails. For this purpose and for these
 reasons they caused skin, hair, and nails to grow at the extremities
 of the limbs. And now that all the parts and members of the mortal
 animal had come together, since its life of necessity consisted of
 fire and breath, and it therefore wasted away by dissolution and
 depletion, the gods contrived the following remedy: They mingled a
 nature akin to that of man with other forms and perceptions, and
 thus created another kind of animal. These are the trees and plants
 and seeds which have been improved by cultivation and are now
 domesticated among us; anciently there were only the will kinds, which
 are older than the cultivated. For everything that partakes of life
 may be truly called a living being, and the animal of which we are now
 speaking partakes of the third kind of soul, which is said to be
 seated between the midriff and the navel, having no part in opinion or
 reason or mind, but only in feelings of pleasure and pain and the
 desires which accompany them. For this nature is always in a passive
 state, revolving in and about itself, repelling the motion from
 without and using its own, and accordingly is not endowed by nature
 with the power of observing or reflecting on its own concerns.
 Wherefore it lives and does not differ from a living being, but is
 fixed and rooted in the same spot, having no power of self-motion.
   Now after the superior powers had created all these natures to be
 food for us who are of the inferior nature, they cut various
 channels through the body as through a garden, that it might be
 watered as from a running stream. In the first place, they cut two
 hidden channels or veins down the back where the skin and the flesh
 join, which answered severally to the right and left side of the body.
 These they let down along the backbone, so as to have the marrow of
 generation between them, where it was most likely to flourish, and
 in order that the stream coming down from above might flow freely to
 the other parts, and equalise the irrigation. In the next place,
 they divided the veins about the head, and interlacing them, they sent
 them in opposite directions; those coming from the right side they
 sent to the left of the body, and those from the left they diverted
 towards the right, so that they and the skin might together form a
 bond which should fasten the head to the body, since the crown of
 the head was not encircled by sinews; and also in order that the
 sensations from both sides might be distributed over the whole body.
 And next, they ordered the water-courses of the body in a manner which
 I will describe, and which will be more easily understood if we
 begin by admitting that all things which have lesser parts retain
 the greater, but the greater cannot retain the lesser. Now of all
 natures fire has the smallest parts, and therefore penetrates
 through earth and water and air and their compounds, nor can
 anything hold it. And a similar principle applies to the human
 belly; for when meats and drinks enter it, it holds them, but it
 cannot hold air and fire, because the particles of which they
 consist are smaller than its own structure.
   These elements, therefore, God employed for the sake of distributing
 moisture from the belly into the veins, weaving together network of
 fire and air like a weel, having at the entrance two lesser weels;
 further he constructed one of these with two openings, and from the
 lesser weels he extended cords reaching all round to the extremities
 of the network. All the interior of the net he made of fire, but the
 lesser weels and their cavity, of air. The network he took and
 spread over the newly-formed animal in the following manner:-He let
 the lesser weels pass into the mouth; there were two of them, and
 one he let down by the air-pipes into the lungs, the other by the side
 of the air-pipes into the belly. The former he divided into two
 branches, both of which he made to meet at the channels of the nose,
 so that when the way through the mouth did not act, the streams of the
 mouth as well were replenished through the nose. With the other cavity
 (i.e. of the greater weel) he enveloped the hollow parts of the
 body, and at one time he made all this to flow into the lesser
 weels, quite gently, for they are composed of air, and at another time
 he caused the lesser weels to flow back again; and the net he made
 to find a way in and out through the pores of the body, and the rays
 of fire which are bound fast within followed the passage of the air
 either way, never at any time ceasing so long as the mortal being
 holds together. This process, as we affirm, the name-giver named
 inspiration and expiration. And all this movement, active as well as
 passive, takes place in order that the body, being watered and cooled,
 may receive nourishment and life; for when the respiration is going in
 and out, and the fire, which is fast bound within, follows it, and
 ever and anon moving to and fro, enters through the belly and
 reaches the meat and drink, it dissolves them, and dividing them
 into small portions and guiding them through the passages where it
 goes, pumps them as from a fountain into the channels of the veins,
 and makes the stream of the veins flow through the body as through a
   Let us once more consider the phenomena of respiration, and
 enquire into the causes which have made it what it is. They are as
 follows:-Seeing that there is no such thing as a vacuum into which any
 of those things which are moved can enter, and the breath is carried
 from us into the external air, the next point is, as will be dear to
 every one, that it does not go into a vacant space, but pushes its
 neighbour out of its place, and that which is thrust out in turn
 drives out its neighbour; and in this everything of necessity at
 last comes round to that place from whence the breath came forth,
 and enters in there, and following the breath, fills up the vacant
 space; and this goes on like the rotation of a wheel, because there
 can be no such thing as a vacuum. Wherefore also the breast and the
 lungs, when they emit the breath, are replenished by the air which
 surrounds the body and which enters in through the pores of the
 flesh and is driven round in a circle; and again, the air which is
 sent away and passes out through the body forces the breath inwards
 through the passage of the mouth and the nostrils. Now the origin of
 this movement may be supposed to be as follows. In the interior of
 every animal the hottest part is that which is around the blood and
 veins; it is in a manner on internal fountain of fire, which we
 compare to the network of a creel, being woven all of fire and
 extended through the centre of the body, while the-outer parts are
 composed of air. Now we must admit that heat naturally proceeds
 outward to its own place and to its kindred element; and as there
 are two exits for the heat, the out through the body, and the other
 through the mouth and nostrils, when it moves towards the one, it
 drives round the air at the other, and that which is driven round
 falls into the fire and becomes warm, and that which goes forth is
 cooled. But when the heat changes its place, and the particles at
 the other exit grow warmer, the hotter air inclining in that direction
 and carried towards its native element, fire, pushes round the air
 at the other; and this being affected in the same way and
 communicating the same impulse, a circular motion swaying to and
 from is produced by the double process, which we call inspiration
 and expiration.
   The phenomena of medical cupping-glasses and of the swallowing of
 drink and of the projection of bodies, whether discharged in the air
 or bowled along the ground, are to be investigated on a similar
 principle; and swift and slow sounds, which appear to be high and low,
 and are sometimes discordant on account of their inequality, and
 then again harmonical on account of the equality of the motion which
 they excite in us. For when the motions of the antecedent swifter
 sounds begin to pause and the two are equalised, the slower sounds
 overtake the swifter and then propel them. When they overtake them
 they do not intrude a new and discordant motion, but introduce the
 beginnings of a slower, which answers to the swifter as it dies
 away, thus producing a single mixed expression out of high and low,
 whence arises a pleasure which even the unwise feel, and which to
 the wise becomes a higher sort of delight, being an imitation of
 divine harmony in mortal motions. Moreover, as to the flowing of
 water, the fall of the thunderbolt, and the marvels that are
 observed about the attraction of amber and the Heraclean stones,-in
 none of these cases is there any attraction; but he who investigates
 rightly, will find that such wonderful phenomena are attributable to
 the combination of certain conditions-the non-existence of a vacuum,
 the fact that objects push one another round, and that they change
 places, passing severally into their proper positions as they are
 divided or combined
   Such as we have seen, is the nature and such are the causes of
 respiration-the subject in which this discussion originated. For the
 fire cuts the food and following the breath surges up within, fire and
 breath rising together and filling the veins by drawing up out of
 the belly and pouring into them the cut portions of the food; and so
 the streams of food are kept flowing through the whole body in all
 animals. And fresh cuttings from kindred substances, whether the
 fruits of the earth or herb of the field, which God planted to be
 our daily food, acquire all sorts of colours by their inter-mixture;
 but red is the most pervading of them, being created by the cutting
 action of fire and by the impression which it makes on a moist
 substance; and hence the liquid which circulates in the body has a
 colour such as we have described. The liquid itself we call blood,
 which nourishes the flesh and the whole body, whence all parts are
 watered and empty places filled.
   Now the process of repletion and evacuation is effected after the
 manner of the universal motion by which all kindred substances are
 drawn towards one another. For the external elements which surround us
 are always causing us to consume away, and distributing and sending
 off like to like; the particles of blood, too, which are divided and
 contained within the frame of the animal as in a sort of heaven, are
 compelled to imitate the motion of the universe. Each, therefore, of
 the divided parts within us, being carried to its kindred nature,
 replenishes the void. When more is taken away than flows in, then we
 decay, and when less, we grow and increase.
   The frame of the entire creature when young has the triangles of
 each kind new, and may be compared to the keel of a vessel which is
 just off the stocks; they are locked firmly together and yet the whole
 mass is soft and delicate, being freshly formed of marrow and nurtured
 on milk. Now when the triangles out of which meats and drinks are
 composed come in from without, and are comprehended in the body, being
 older and weaker than the triangles already there, the frame of the
 body gets the better of them and its newer triangles cut them up,
 and so the animal grows great, being nourished by a multitude of
 similar particles. But when the roots of the triangles are loosened by
 having undergone many conflicts with many things in the course of
 time, they are no longer able to cut or assimilate the food which
 enters, but are themselves easily divided by the bodies which come
 in from without. In this way every animal is overcome and decays,
 and this affection is called old age. And at last, when the bonds by
 which the triangles of the marrow are united no longer hold, and are
 parted by the strain of existence, they in turn loosen the bonds of
 the soul, and she, obtaining a natural release, flies away with joy.
 For that which takes place according to nature is pleasant, but that
 which is contrary to nature is painful. And thus death, if caused by
 disease or produced by wounds, is painful and violent; but that sort
 of death which comes with old age and fulfils the debt of nature is
 the easiest of deaths, and is accompanied with pleasure rather than
 with pain.
   Now every one can see whence diseases arise. There are four
 natures out of which the body is compacted, earth and fire and water
 and air, and the unnatural excess or defect of these, or the change of
 any of them from its own natural place into another, or-since there
 are more kinds than one of fire and of the other elements-the
 assumption by any of these of a wrong kind, or any similar
 irregularity, produces disorders and diseases; for when any of them is
 produced or changed in a manner contrary to nature, the parts which
 were previously cool grow warm, and those which were dry become moist,
 and the light become heavy, and the heavy light; all sorts of
 changes occur. For, as we affirm, a thing can only remain the same
 with itself, whole and sound, when the same is added to it, or
 subtracted from it, in the same respect and in the same manner and
 in due proportion; and whatever comes or goes away in violation of
 these laws causes all manner of changes and infinite diseases and
 corruptions. Now there is a second class of structures which are
 also natural, and this affords a second opportunity of observing
 diseases to him who would understand them. For whereas marrow and bone
 and flesh and sinews are composed of the four elements, and the blood,
 though after another manner, is likewise formed out of them, most
 diseases originate in the way which I have described; but the worst of
 all owe their severity to the fact that the generation of these
 substances stances in a wrong order; they are then destroyed. For
 the natural order is that the flesh and sinews should be made of
 blood, the sinews out of the fibres to which they are akin, and the
 flesh out of the dots which are formed when the fibres are
 separated. And the glutinous and rich matter which comes away from the
 sinews and the flesh, not only glues the flesh to the bones, but
 nourishes and imparts growth to the bone which surrounds the marrow;
 and by reason of the solidity of the bones, that which filters through
 consists of the purest and smoothest and oiliest sort of triangles,
 dropping like dew from the bones and watering the marrow.
   Now when each process takes place in this order, health commonly
 results; when in the opposite order, disease. For when the flesh
 becomes decomposed and sends back the wasting substance into the
 veins, then an over-supply of blood of diverse kinds, mingling with
 air in the veins, having variegated colours and bitter properties,
 as well as acid and saline qualities, contains all sorts of bile and
 serum and phlegm. For all things go the wrong way, and having become
 corrupted, first they taint the blood itself, and then ceasing to give
 nourishment the body they are carried along the veins in all
 directions, no longer preserving the order of their natural courses,
 but at war with themselves, because they receive no good from one
 another, and are hostile to the abiding constitution of the body,
 which they corrupt and dissolve. The oldest part of the flesh which is
 corrupted, being hard to decompose, from long burning grows black, and
 from being everywhere corroded becomes bitter, and is injurious to
 every part of the body which is still uncorrupted. Sometimes, when the
 bitter element is refined away, the black part assumes an acidity
 which takes the place of the bitterness; at other times the bitterness
 being tinged with blood has a redder colour; and this, when mixed with
 black, takes the hue of grass; and again, an auburn colour mingles
 with the bitter matter when new flesh is decomposed by the fire
 which surrounds the internal flame-to all which symptoms some
 physician perhaps, or rather some philosopher, who had the power of
 seeing in many dissimilar things one nature deserving of a name, has
 assigned the common name of bile. But the other kinds of bile are
 variously distinguished by their colours. As for serum, that sort
 which is the watery part of blood is innocent, but that which is a
 secretion of black and acid bile is malignant when mingled by the
 power of heat with any salt substance, and is then called acid phlegm.
  Again, the substance which is formed by the liquefaction of new and
 tender flesh when air is present, if inflated and encased in liquid so
 as to form bubbles, which separately are invisible owing to their
 small size, but when collected are of a bulk which is visible, and
 have a white colour arising out of the generation of foam-all this
 decomposition of tender flesh when inter-mingled with air is termed by
 us white phlegm. And the whey or sediment of newly-formed phlegm is
 sweat and tears, and includes the various daily discharges by which
 the body is purified. Now all these become causes of disease when
 the blood is not replenished in a natural manner by food and drink but
 gains bulk from opposite sources in violation of the laws of nature.
 When the several parts of the flesh are separated by disease, if the
 foundation remains, the power of the disorder is only half as great,
 and there is still a prospect of an easy recovery; but when that which
 binds the flesh to the bones is diseased, and no longer being
 separated from the muscles and sinews, ceases to give nourishment to
 the bone and to unite flesh and bone, and from being oily and smooth
 and glutinous becomes rough and salt and dry, owing to bad regimen,
 then all the substance thus corrupted crumbles away under the flesh
 and the sinews, and separates from the bone, and the fleshy parts fall
 away from their foundation and leave the sinews bare and full of
 brine, and the flesh again gets into the circulation of the blood
 and makes the previously-mentioned disorders still greater. And if
 these bodily affections be severe, still worse are the prior
 disorders; as when the bone itself, by reason of the density of the
 flesh, does not obtain sufficient air, but becomes mouldy and hot
 and gangrened and receives no nutriment, and the natural process is
 inverted, and the bone crumbling passes into the food, and the food
 into the flesh, and the flesh again falling into the blood makes all
 maladies that may occur more virulent than those already mentioned.
 But the worst case of all is when the marrow is diseased, either
 from excess or defect; and this is the cause of the very greatest
 and most fatal disorders, in which the whole course of the body is
   There is a third class of diseases which may be conceived of as
 arising in three ways; for they are produced sometimes by wind, and
 sometimes by phlegm, and sometimes by bile. When the lung, which is
 the dispenser of the air to the body, is obstructed by rheums and
 its passages are not free, some of them not acting, while through
 others too much air enters, then the parts which are unrefreshed by
 air corrode, while in other parts the excess of air forcing its way
 through the veins distorts them and decomposing the body is enclosed
 in the midst of it and occupies the midriff thus numberless painful
 diseases are produced, accompanied by copious sweats. And oftentimes
 when the flesh is dissolved in the body, wind, generated within and
 unable to escape, is the source of quite as much pain as the air
 coming in from without; but the greatest pain is felt when the wind
 gets about the sinews and the veins of the shoulders, and swells
 them up, so twists back the great tendons and the sinews which are
 connected with them. These disorders are called tetanus and
 opisthotonus, by reason of the tension which accompanies them. The
 cure of them is difficult; relief is in most cases given by fever
 supervening. The white phlegm, though dangerous when detained within
 by reason of the air-bubbles, yet if it can communicate with the
 outside air, is less severe, and only discolours the body,
 generating leprous eruptions and similar diseases. When it is
 mingled with black bile and dispersed about the courses of the head,
 which are the divinest part of us, the attack if coming on in sleep,
 is not so severe; but when assailing those who are awake it is hard to
 be got rid of, and being an affection of a sacred part, is most justly
 called sacred. An acid and salt phlegm, again, is the source of all
 those diseases which take the form of catarrh, but they have many
 names because the places into which they flow are manifold.
   Inflammations of the body come from burnings and inflamings, and all
 of them originate in bile. When bile finds a means of discharge, it
 boils up and sends forth all sorts of tumours; but when imprisoned
 within, it generates many inflammatory diseases, above all when
 mingled with pure blood; since it then displaces the fibres which
 are scattered about in the blood and are designed to maintain the
 balance of rare and dense, in order that the blood may not be so
 liquefied by heat as to exude from the pores of the body, nor again
 become too dense and thus find a difficulty in circulating through the
 veins. The fibres are so constituted as to maintain this balance;
 and if any one brings them all together when the blood is dead and
 in process of cooling, then the blood which remains becomes fluid, but
 if they are left alone, they soon congeal by reason of the surrounding
 cold. The fibres having this power over the blood, bile, which is only
 stale blood, and which from being flesh is dissolved again into blood,
 at the first influx coming in little by little, hot and liquid, is
 congealed by the power of the fibres; and so congealing and made to
 cool, it produces internal cold and shuddering. When it enters with
 more of a flood and overcomes the fibres by its heat, and boiling up
 throws them into disorder, if it have power enough to maintain its
 supremacy, it penetrates the marrow and burns up what may be termed
 the cables of the soul, and sets her free; but when there is not so
 much of it, and the body though wasted still holds out, the bile is
 itself mastered, and is either utterly banished, or is thrust
 through the veins into the lower or upper-belly, and is driven out
 of the body like an exile from a state in which there has been civil
 war; whence arise diarrhoeas and dysenteries, and all such
 disorders. When the constitution is disordered by excess of fire,
 continuous heat and fever are the result; when excess of air is the
 cause, then the fever is quotidian; when of water, which is a more
 sluggish element than either fire or air, then the fever is a tertian;
 when of earth, which is the most sluggish of the four, and is only
 purged away in a four-fold period, the result is a quartan fever,
 which can with difficulty be shaken off.
   Such is the manner in which diseases of the body arise; the
 disorders of the soul, which depend upon the body, originate as
 follows. We must acknowledge disease of the mind to be a want of
 intelligence; and of this there are two kinds; to wit, madness and
 ignorance. In whatever state a man experiences either of them, that
 state may be called disease; and excessive pains and pleasures are
 justly to be regarded as the greatest diseases to which the soul is
 liable. For a man who is in great joy or in great pain, in his
 unseasonable eagerness to attain the one and to avoid the other, is
 not able to see or to hear anything rightly; but he is mad, and is
 at the time utterly incapable of any participation in reason. He who
 has the seed about the spinal marrow too plentiful and overflowing,
 like a tree overladen with fruit, has many throes, and also obtains
 many pleasures in his desires and their offspring, and is for the most
 part of his life deranged, because his pleasures and pains are so very
 great; his soul is rendered foolish and disordered by his body; yet he
 is regarded not as one diseased, but as one who is voluntarily bad,
 which is a mistake. The truth is that the intemperance of love is a
 disease of the soul due chiefly to the moisture and fluidity which
 is produced in one of the elements by the loose consistency of the
 bones. And in general, all that which is termed the incontinence of
 pleasure and is deemed a reproach under the idea that the wicked
 voluntarily do wrong is not justly a matter for reproach. For no man
 is voluntarily bad; but the bad become bad by reason of an ill
 disposition of the body and bad education, things which are hateful to
 every man and happen to him against his will. And in the case of
 pain too in like manner the soul suffers much evil from the body.
 For where the acid and briny phlegm and other bitter and bilious
 humours wander about in the body, and find no exit or escape, but
 are pent up within and mingle their own vapours with the motions of
 the soul, and are blended, with them, they produce all sorts of
 diseases, more or fewer, and in every degree of intensity; and being
 carried to the three places of the soul, whichever they may
 severally assail, they create infinite varieties of ill-temper and
 melancholy, of rashness and cowardice, and also of forgetfulness and
 stupidity. Further, when to this evil constitution of body evil
 forms of government are added and evil discourses are uttered in
 private as well as in public, and no sort of instruction is given in
 youth to cure these evils, then all of us who are bad become bad
 from two causes which are entirely beyond our control. In such cases
 the planters are to blame rather than the plants, the educators rather
 than the educated. But however that may be, we should endeavour as far
 as we can by education, and studies, and learning, to avoid vice and
 attain virtue; this, however, is part of another subject.
   There is a corresponding enquiry concerning the mode of treatment by
 which the mind and the body are to be preserved, about which it is
 meet and right that I should say a word in turn; for it is more our
 duty to speak of the good than of the evil. Everything that is good is
 fair, and the animal fair is not without proportion, and the animal
 which is to be fair must have due proportion. Now we perceive lesser
 symmetries or proportions and reason about them, but of the highest
 and greatest we take no heed; for there is no proportion or
 disproportion more productive of health and disease, and virtue and
 vice, than that between soul and body. This however we do not
 perceive, nor do we reflect that when a weak or small frame is the
 vehicle of a great and mighty soul, or conversely, when a little
 soul is encased in a large body, then the whole animal is not fair,
 for it lacks the most important of all symmetries; but the due
 proportion of mind and body is the fairest and loveliest of all sights
 to him who has the seeing eye. Just as a body which has a leg too
 long, or which is unsymmetrical in some other respect, is an
 unpleasant sight, and also, when doing its share of work, is much
 distressed and makes convulsive efforts, and often stumbles through
 awkwardness, and is the cause of infinite evil to its own self-in like
 manner we should conceive of the double nature which we call the
 living being; and when in this compound there is an impassioned soul
 more powerful than the body, that soul, I say, convulses and fills
 with disorders the whole inner nature of man; and when eager in the
 pursuit of some sort of learning or study, causes wasting; or again,
 when teaching or disputing in private or in public, and strifes and
 controversies arise, inflames and dissolves the composite frame of man
 and introduces rheums; and the nature of this phenomenon is not
 understood by most professors of medicine, who ascribe it to the
 opposite of the real cause. And once more, when body large and too
 strong for the soul is united to a small and weak intelligence, then
 inasmuch as there are two desires natural to man,-one of food for
 the sake of the body, and one of wisdom for the sake of the diviner
 part of us-then, I say, the motions of the stronger, getting the
 better and increasing their own power, but making the soul dull, and
 stupid, and forgetful, engender ignorance, which is the greatest of
 diseases. There is one protection against both kinds of
 disproportion:-that we should not move the body without the soul or
 the soul without the body, and thus they will be on their guard
 against each other, and be healthy and well balanced. And therefore
 the mathematician or any one else whose thoughts are much absorbed
 in some intellectual pursuit, must allow his body also to have due
 exercise, and practise gymnastic; and he who is careful to fashion the
 body, should in turn impart to the soul its proper motions, and should
 cultivate music and all philosophy, if he would deserve to be called
 truly fair and truly good. And the separate parts should be treated in
 the same manner, in imitation of the pattern of the universe; for as
 the body is heated and also cooled within by the elements which
 enter into it, and is again dried up and moistened by external things,
 and experiences these and the like affections from both kinds of
 motions, the result is that the body if given up to motion when in a
 state of quiescence is overmastered and perishes; but if any one, in
 imitation of that which we call the foster-mother and nurse of the
 universe, will not allow the body ever to be inactive, but is always
 producing motions and agitations through its whole extent, which
 form the natural defence against other motions both internal and
 external, and by moderate exercise reduces to order according to their
 affinities the particles and affections which are wandering about
 the body, as we have already said when speaking of the universe, he
 will not allow enemy placed by the side of enemy to stir up wars and
 disorders in the body, but he will place friend by the side of friend,
 so as to create health.
   Now of all motions that is the best which is produced in a thing
 by itself, for it is most akin to the motion of thought and of the
 universe; but that motion which is caused by others is not so good,
 and worst of all is that which moves the body, when at rest, in
 parts only and by some external agency. Wherefore of all modes of
 purifying and reuniting the body the best is gymnastic; the next
 best is a surging motion, as in sailing or any other mode of
 conveyance which is not fatiguing; the third sort of motion may be
 of use in a case of extreme necessity, but in any other will be
 adopted by no man of sense: I mean the purgative treatment of
 physicians; for diseases unless they are very dangerous should not
 be irritated by medicines, since every form of disease is in a
 manner akin to the living being, whose complex frame has an
 appointed term of life. For not the whole race only, but each
 individual-barring inevitable accidents-comes into the world having
 a fixed span, and the triangles in us are originally framed with power
 to last for a certain time, beyond which no man prolong his life.
 And this holds also of the constitution of diseases; if any one
 regardless of the appointed time tries to subdue them by medicine,
 he only aggravates and multiplies them. Wherefore we ought always to
 manage them by regimen, as far as a man can spare the time, and not
 provoke a disagreeable enemy by medicines.
   Enough of the composite animal, and of the body which is a part of
 him, and of the manner in which a man may train and be trained by
 himself so as to live most according to reason: and we must above
 and before all provide that the element which is to train him shall be
 the fairest and best adapted to that purpose. A minute discussion of
 this subject would be a serious task; but if, as before, I am to
 give only an outline, the subject may not unfitly be summed up as
   I have often remarked that there are three kinds of soul located
 within us, having each of them motions, and I must now repeat in the
 fewest words possible, that one part, if remaining inactive and
 ceasing from its natural motion, must necessarily become very weak,
 but that which is trained and exercised, very strong. Wherefore we
 should take care that the movements of the different parts of the soul
 should be in due proportion.
   And we should consider that God gave the sovereign part of the human
 soul to be the divinity of each one, being that part which, as we say,
 dwells at the top of the body, inasmuch as we are a plant not of an
 earthly but of a heavenly growth, raises us from earth to our
 kindred who are in heaven. And in this we say truly; for the divine
 power suspended the head and root of us from that place where the
 generation of the soul first began, and thus made the whole body
 upright. When a man is always occupied with the cravings of desire and
 ambition, and is eagerly striving to satisfy them, all his thoughts
 must be mortal, and, as far as it is possible altogether to become
 such, he must be mortal every whit, because he has cherished his
 mortal part. But he who has been earnest in the love of knowledge
 and of true wisdom, and has exercised his intellect more than any
 other part of him, must have thoughts immortal and divine, if he
 attain truth, and in so far as human nature is capable of sharing in
 immortality, he must altogether be immortal; and since he is ever
 cherishing the divine power, and has the divinity within him in
 perfect order, he will be perfectly happy. Now there is only one way
 of taking care of things, and this is to give to each the food and
 motion which are natural to it. And the motions which are naturally
 akin to the divine principle within us are the thoughts and
 revolutions of the universe. These each man should follow, and correct
 the courses of the head which were corrupted at our birth, and by
 learning the harmonies and revolutions of the universe, should
 assimilate the thinking being to the thought, renewing his original
 nature, and having assimilated them should attain to that perfect life
 which the gods have set before mankind, both for the present and the
   Thus our original design of discoursing about the universe down to
 the creation of man is nearly completed. A brief mention may be made
 of the generation of other animals, so far as the subject admits of
 brevity; in this manner our argument will best attain a due
 proportion. On the subject of animals, then, the following remarks may
 be offered. Of the men who came into the world, those who were cowards
 or led unrighteous lives may with reason be supposed to have changed
 into the nature of women in the second generation. And this was the
 reason why at that time the gods created in us the desire of sexual
 intercourse, contriving in man one animated substance, and in woman
 another, which they formed respectively in the following manner. The
 outlet for drink by which liquids pass through the lung under the
 kidneys and into the bladder, which receives then by the pressure of
 the air emits them, was so fashioned by them as to penetrate also into
 the body of the marrow, which passes from the head along the neck
 and through the back, and which in the preceding discourse we have
 named the seed. And the seed having life, and becoming endowed with
 respiration, produces in that part in which it respires a lively
 desire of emission, and thus creates in us the love of procreation.
 Wherefore also in men the organ of generation becoming rebellious
 and masterful, like an animal disobedient to reason, and maddened with
 the sting of lust, seeks to gain absolute sway; and the same is the
 case with the so-called womb or matrix of women; the animal within
 them is desirous of procreating children, and when remaining
 unfruitful long beyond its proper time, gets discontented and angry,
 and wandering in every direction through the body, closes up the
 passages of the breath, and, by obstructing respiration, drives them
 to extremity, causing all varieties of disease, until at length the
 desire and love of the man and the woman, bringing them together and
 as it were plucking the fruit from the tree, sow in the womb, as in
 a field, animals unseen by reason of their smallness and without form;
 these again are separated and matured within; they are then finally
 brought out into the light, and thus the generation of animals is
   Thus were created women and the female sex in general. But the
 race of birds was created out of innocent light-minded men, who,
 although their minds were directed toward heaven, imagined, in their
 simplicity, that the clearest demonstration of the things above was to
 be obtained by sight; these were remodelled and transformed into
 birds, and they grew feathers instead of hair. The race of wild
 pedestrian animals, again, came from those who had no philosophy in
 any of their thoughts, and never considered at all about the nature of
 the heavens, because they had ceased to use the courses of the head,
 but followed the guidance of those parts of the soul which are in
 the breast. In consequence of these habits of theirs they had their
 front-legs and their heads resting upon the earth to which they were
 drawn by natural affinity; and the crowns of their heads were
 elongated and of all sorts of shapes, into which the courses of the
 soul were crushed by reason of disuse. And this was the reason why
 they were created quadrupeds and polypods: God gave the more senseless
 of them the more support that they might be more attracted to the
 earth. And the most foolish of them, who trail their bodies entirely
 upon the ground and have no longer any need of feet, he made without
 feet to crawl upon the earth. The fourth class were the inhabitants of
 the water: these were made out of the most entirely senseless and
 ignorant of all, whom the transformers did not think any longer worthy
 of pure respiration, because they possessed a soul which was made
 impure by all sorts of transgression; and instead of the subtle and
 pure medium of air, they gave them the deep and muddy sea to be
 their element of respiration; and hence arose the race of fishes and
 oysters, and other aquatic animals, which have received the most
 remote habitations as a punishment of their outlandish ignorance.
 These are the laws by which animals pass into one another, now, as
 ever, changing as they lose or gain wisdom and folly.
   We may now say that our discourse about the nature of the universe
 has an end. The world has received animals, mortal and immortal, and
 is fulfilled with them, and has become a visible animal containing the
 visible-the sensible God who is the image of the intellectual, the
 greatest, best, fairest, most perfect-the one only begotten heaven.
