WE have seen that according to a widespread belief, which is not without a foundation in fact, plants reproduce their kinds through the sexual union of male and female elements, and that on the principle of homoeopathic or imitative magic this reproduction is supposed to be stimulated by the real or mock marriage of men and women, who masquerade for the time being as spirits of vegetation. Such magical dramas have played a great part in the popular festivals of Europe, and based as they are on a very crude conception of natural law, it is clear that they must have been handed down from a remote antiquity. We shall hardly, therefore, err in assuming that they date from a time when the forefathers of the civilised nations of Europe were still barbarians, herding their cattle and cultivating patches of corn in the clearings of the vast forests, which then covered the greater part of the continent, from the Mediterranean to the Arctic Ocean. But if these old spells and enchantments for the growth of leaves and blossoms, of grass and flowers and fruit, have lingered down to our own time in the shape of pastoral plays and popular merry-makings, is it not reasonable to suppose that they survived in less attenuated forms some two thousand years ago among the civilised peoples of antiquity? Or, to put it otherwise, is it not likely that in certain festivals of the ancients we may be able to detect the equivalents of our May Day, Whitsuntide, and Midsummer celebrations, with this difference, that in those days the ceremonies had not yet dwindled into mere shows and pageants, but were still religious or magical rites, in which the actors consciously supported the high parts of gods and goddesses? Now in the first chapter of this book we found reason to believe that the priest who bore the title of King of the Wood at Nemi had for his mate the goddess of the grove, Diana herself. May not he and she, as King and Queen of the Wood, have been serious counterparts of the merry mummers who play the King and Queen of May, the Whitsuntide Bridegroom and Bride in modern Europe? and may not their union have been yearly celebrated in a theogamy or divine marriage? Such dramatic weddings of gods and goddesses, as we shall see presently, were carried out as solemn religious rites in many parts of the ancient world; hence there is no intrinsic improbability in the supposition that the sacred grove at Nemi may have been the scene of an annual ceremony of this sort. Direct evidence that it was so there is none, but analogy pleads in favour of the view, as I shall now endeavour to show. 1
Diana was essentially a goddess of the woodlands, as Ceres was a goddess of the corn and Bacchus a god of the vine. Her sanctuaries were commonly in groves, indeed every grove was sacred to her, and she is often associated with the forest god Silvanus in dedications. But whatever her origin may have been, Diana was not always a mere goddess of trees. Like her Greek sister Artemis, she appears to have developed into a personification of the teeming life of nature, both animal and vegetable. As mistress of the greenwood she would naturally be thought to own the beasts, whether wild or tame, that ranged through it, lurking for their prey in its gloomy depths, munching the fresh leaves and shoots among the boughs, or cropping the herbage in the open glades and dells. Thus she might come to be the patron goddess both of hunters and herdsmen, just as Silvanus was the god not only of woods, but of cattle. Similarly in Finland the wild beasts of the forest were regarded as the herds of the woodland god Tapio and of his stately and beautiful wife. No man might slay one of these animals without the gracious permission of their divine owners. Hence the hunter prayed to the sylvan deities, and vowed rich offerings to them if they would drive the game across his path. And cattle also seem to have enjoyed the protection of those spirits of the woods, both when they were in their stalls and while they strayed in the forest. Before the Gayos of Sumatra hunt deer, wild goats, or wild pigs with hounds in the woods, they deem it necessary to obtain the leave of the unseen Lord of the forest. This is done according to a prescribed form by a man who has special skill in woodcraft. He lays down a quid of betel before a stake which is cut in a particular way to represent the Lord of the Wood, and having done so he prays to the spirit to signify his consent or refusal. In his treatise on hunting, Arrian tells us that the Celts used to offer an annual sacrifice to Artemis on her birthday, purchasing the sacrificial victim with the fines which they had paid into her treasury for every fox, hare, and roe that they had killed in the course of the year. The custom clearly implied that the wild beasts belonged to the goddess, and that she must be compensated for their slaughter. 2
But Diana was not merely a patroness of wild beasts, a mistress of woods and hills, of lonely glades and sounding rivers; conceived as the moon, and especially, it would seem, as the yellow harvest moon, she filled the farmer’s grange with goodly fruits, and heard the prayers of women in travail. In her sacred grove at Nemi, as we have seen, she was especially worshipped as a goddess of childbirth, who bestowed offspring on men and women. Thus Diana, like the Greek Artemis, with whom she was constantly identified, may be described as a goddess of nature in general and of fertility in particular. We need not wonder, therefore, that in her sanctuary on the Aventine she was represented by an image copied from the many-breasted idol of the Ephesian Artemis, with all its crowded emblems of exuberant fecundity. Hence too we can understand why an ancient Roman law, attributed to King Tullus Hostilius, prescribed that, when incest had been committed, an expiatory sacrifice should be offered by the pontiffs in the grove of Diana. For we know that the crime of incest is commonly supposed to cause a dearth; hence it would be meet that atonement for the offence should be made to the goddess of fertility. 3
Now on the principle that the goddess of fertility must herself be fertile, it behoved Diana to have a male partner. Her mate, if the testimony of Servius may be trusted, was that Virbius who had his representative, or perhaps rather his embodiment, in the King of the Wood at Nemi. The aim of their union would be to promote the fruitfulness of the earth, of animals, and of mankind; and it might naturally be thought that this object would be more surely attained if the sacred nuptials were celebrated every year, the parts of the divine bride and bridegroom being played either by their images or by living persons. No ancient writer mentions that this was done in the grove at Nemi; but our knowledge of the Arician ritual is so scanty that the want of information on this head can hardly count as a fatal objection to the theory. That theory, in the absence of direct evidence, must necessarily be based on the analogy of similar customs practised elsewhere. Some modern examples of such customs, more or less degenerate, were described in the last chapter. Here we shall consider their ancient counterparts. 4
