All this while Sir Percivale had pursued adventures of his own, and came nigh unto losing his life, but he was saved from his enemies by the good Knight, Sir Galahad, whom he did not know, although he was seeking him, for Sir Galahad now bore a red shield, and not a white one. And at last the foes fled deep into the forest, and Sir Galahad followed; but Sir Percivale had no horse and was forced to stay behind. Then his eyes were opened, and he knew it was Sir Galahad who had come to his help, and he sat down under a tree and grieved sore.
While he was sitting there a Knight passed by riding a black horse, and when he was out of sight a yeoman came pricking after as fast as he might, and, seeing Sir Percivale, asked if he had seen a Knight mounted on a black horse. 'Yes, Sir, forsooth,' answered Sir Percivale, 'why do you want to know?' 'Ah, Sir, that is my steed which he has taken from me, and wherever my lord shall find me, he is sure to slay me.' 'Well,' said Sir Percivale, 'thou seest that I am on foot, but had I a good horse I would soon come up with him.' 'Take my hackney,' said the yeoman, 'and do the best you can, and I shall follow you on foot to watch how you speed.' So Sir Percivale rode as fast as he might, and at last he saw that Knight, and he hailed him. The Knight turned and set his spear against Sir Percivale, and smote the hackney in the breast, so that he fell dead to the earth, and Sir Percivale fell with him; then the Knight rode away. But Sir Percivale was mad with wrath, and cried to the Knight to return and fight with him on foot,
and the Knight answered not and went on his way. When Sir Percivale saw that he would not turn, he threw himself on the ground, and cast away his helm and sword, and bemoaned himself for the most unhappy of all Knights; and there he abode the whole day, and, being faint and weary, slept till it was midnight. And at midnight he waked and saw before him a woman, who said to him right fiercely, 'Sir Percivale, what doest thou here?' 'Neither good nor great ill,' answered he. 'If thou wilt promise to do my will when I call upon you,' said she, 'I will lend you my own horse, and he shall bear thee whither thou shalt choose.' This Sir Percivale promised gladly, and the woman went and returned with a black horse, so large and well-apparelled that Sir Percivale marvelled. But he mounted him gladly, and drove in his spurs, and within an hour and less the horse bare him four days' journey hence, and would have borne him into a rough water that roared, had not Sir Percivale pulled at his bridle. The Knight stood doubting, for the water made a great noise, and he feared lest his horse could not get through it. Still, wishing greatly to pass over, he made himself ready, and signed the sign of the cross upon his forehead.
At that the fiend which had taken the shape of a horse shook off Sir Percivale and dashed into the water, crying and making great sorrow; and it seemed to him that the water burned. Then Sir Percivale knew that it was not a horse but a fiend, which would have brought him to perdition, and he gave thanks and prayed all that night long. As soon as it was day he looked about him, and saw he was in a wild mountain, girt round with the sea and filled with wild beasts. Then he rose and went into a valley, and there he saw a young serpent bring a young lion by the neck, and after that there passed a great lion, crying and roaring after the serpent, and a fierce battle began between them. Sir Percivale thought to help the lion, as he was the more
natural beast of the twain, and he drew his sword and set his shield before him, and gave the serpent a deadly buffet. When the lion saw that, he made him all the cheer that a beast might make a man, and fawned about him like a spaniel, and stroked him with his paws. And about noon the lion took his little whelp, and placed him on his back, and bare him home again, and Sir Percivale, being left alone, prayed till he was comforted. But at eventide the lion returned, and couched down at his feet, and all night long he and the lion slept together.
