Of the Great Danger That Sir Percivale Was in by His Horse, and How He Saw a Serpent and a Lion Fight
AND when Sir Percivale came nigh the brim, and saw the water so boistous, he doubted to overpass it. And then he made a sign of the cross on his forehead. When the fiend felt him so charged he shook off Sir Percivale, and he went into the water crying and roaring, making great sorrow, and it seemed unto him that the water brent. Then Sir Percivale perceived it 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; and so he prayed all that night till on the morn that it was day; then he saw that he was in a wild mountain the which was closed with the sea nigh all about, that he might see no land about him which might relieve him, but wild beasts. And then he went into a valley, and there he saw a young serpent bring a young lion by the neck, and so he came by Sir Percivale. With that came a great lion crying and roaring after the serpent. And as fast as Sir Percivale saw this he marvelled, and hied him thither, but anon the lion had overtaken the serpent and began battle with him. And then Sir Percivale thought to help the lion for he was the more natural beast of the two; and therewith he drew his sword, and set his shield afore him, and there he gave the serpent such a buffet that he had a deadly wound. When the lion saw that, he made no resemblant to fight with him, but made him all the cheer that a beast might make a man. Then Percivale perceived that, and cast down his shield which was broken; and then he did off his helm for to gather wind, for he was greatly enchafed with the serpent: and the lion went alway about him fawning as a spaniel. And then he stroked him on the neck and on the shoulders. And then he thanked God of the fellowship of that beast. And about noon the lion took his little whelp and trussed him and bare him there he came from. Then was Sir Percivale alone. And as the tale telleth, he was one of the men of the world at that time which most believed in our Lord Jesus Christ, for in those days there were but few folks that believed in God perfectly. For in those days the son spared not the father no more than a stranger. And so Sir Percivale comforted himself in our Lord Jesus, and besought God no temptation should bring him out of Gods service, but to endure as his true champion. Thus when Sir Percivale had prayed he saw the lion come toward him, and then he couched down at his feet. And so all that night the lion and he slept together; and when Sir Percivale slept he dreamed a marvellous dream, that there two ladies met with him, and that one sat upon a lion, and that other sat upon a serpent, and that one of them was young, and the other was old; and the youngest him thought said: Sir Percivale, my lord saluteth thee, and sendeth thee word that thou array thee and make thee ready, for tomorn thou must fight with the strongest champion of the world. And if thou be overcome thou shalt not be quit for losing of any of thy members, but thou shalt be shamed for ever to the worlds end. And then he asked her what was her lord. And she said the greatest lord of all the world: and so she departed suddenly that he wist not where.
