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 in 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.
