Within an hour, and less, the black steed bare him four day's journey thence, till he came to a rough water the which roared, and his horse would have borne him into it. And when Sir Percivale came nigh the brim, and saw the water so boisterous, he feared to overpass it. Then he made a sign of the cross in his forehead, whereupon the horse shook off Sir Percivale, and he fell into the water, crying and roaring, making great sorrow; and it seemed unto him that the water burned. Then Sir Percivale perceived the steed was a fiend, the which would have brought him unto his perdition. Then he commended himself unto God, and prayed our Lord to keep him from all such temptations. So he prayed all that night till it was day. Then he saw that he was in a wild mountain the which was closed with the sea nigh all about, so that he might see no land about him which might relieve him. Then was Sir Percivale ware in the sea, and saw a ship come sailing towards him; and he went unto the ship, and found it covered within and without with white samite. At the board stood an old man clothed in a surplice in likeness of a priest. "Sir," said Sir Percivale, "ye be welcome." "God keep you," said the good man, "of whence be ye?" "Sir," said Sir Percivale, "I am of King Arthur's court, and a knight of the Table Round, the which am in the quest of the Holy Grail. Here I am in great duress, and never likely to escape out of this wilderness." "Doubt not," said the good man, "if ye be so true a knight as the order of chivalry requireth, and of heart as ye ought to be, ye need not fear that any enemy shall slay you." "What are ye?" said Sir Percivale. "Sir," said the old man, "I am of a strange country, and hither I come to comfort you, and to warn you of your great battle that shall befall you." "With whom," said Sir Percivale, "shall I fight?" "With the most champion of the world," said the old man, "but, if ye quit you well, ye shall lose no limb, even though vanquished and seemingly shamed to the world's end." Then the good man leaped over the board, and the ship and all went away, Sir Percivale wist not whither. He abode there till midday, when he saw a ship come rowing in the sea as if all the winds of the world had driven it. It drove under the rock on which he sat; and when he hied thither he found the ship covered with silk blacker than any bier, and therein was a gentlewoman of great beauty, and she was clothed richly that none might be better. When she saw Sir Percivale, she said, "Who brought you in this wilderness where ye be never like to pass hence? for ye shall die here for hunger and mischief." "Damsel," said Sir Percivale, "I serve the best man of the world, and in His service He will not suffer me to die, for who that knocketh shall enter, and who that asketh shall have, and from the man that seeketh Him, He hideth Him not." "And I came out of the waste forest where I found the red knight with the white shield," said the damsel.
