So while the mind of Sir Percival was elsewhere, the horse which he rode slipped his foot upon a round, loose stone, and the stone turned under the horse’s foot so that it strained its shoulder. At first Sir Percival knew naught of this mishap, but presently, anon, the horse began to limp as it walked. And every minute the horse of Sir Percival limped worse than it had limped the minute before. So Sir Percival wist not what to do, for here was he with a horse that could not fare farther with him, and there was no house within sight, and there was no person within sight upon all that barren waste. So Sir Percival dismounted from his horse, and he took the bridle of the horse over his arm, and so he walked with the bridle over his arm and the horse limped behind him. Thus he travelled for a great way, and anon he left that stony waste behind him, and came to a country where green things grew. And anon after that he came to a place that was spread all over with fertile fields of grass interspersed with plantations of trees, both oak trees and elm trees. [Sidenote: _Sir Percival meeteth a damsel in red._] Here, passing by a small fountain of water, he beheld a fair damsel sitting beside the margin of that fountain, and the damsel was clad all in red, from top to toe. This damsel had with her a palfrey and a great black horse beside that palfrey, and the black horse was very remarkable for breadth and sinew, for his shoulders were deep and his legs were corded with muscles, and his fetlocks were adorned with long and curling hairs, and his eyes were very bright and shining as with fire beneath them, and his ears were sharp and pointed, as though they had been cut with a fine knife, and his mane and tail were thick and black, like the clouds of night, and there was not a white hair upon him, from the tip of his nose to the end of his tail. [Sidenote: _The damsel giveth a horse to Sir Percival._] Quoth Sir Percival, “Hah, maiden, that is a fine horse that thou hast there.” Said she, “Yea, Messire; he is a very fine horse.” Said Sir Percival, “I would that thou wouldst sell me that horse; for mine own, as thou seest, is gone lame.” The maiden said, “Sir, are you not Sir Percival of Gales?” Then Sir Percival was greatly astonished that the damsel should know him, and he said, “Yea, damsel, that is my name.” “Then,” quoth she, “I cannot accept money from you for this horse. But if you will take him for your own, then you may have him. So leave you your lame horse here, and take this horse instead of it. For wit you I have been sent with this horse that you might have it to ride upon.”
