How Sir Launcelot in his madness took a sword and fought with a knight, and leapt in a bed.
And now leave we of a while of Sir Ector and of Sir Percivale, and speak we of Sir Launcelot that suffered and endured many sharp showers, that ever ran wild wood from place to place, and lived by fruit and such as he might get, and drank water two year; and other clothing had he but little but his shirt and his breech. Thus as Sir Launcelot wandered here and there he came in a fair meadow where he found a pavilion; and there by, upon a tree, there hung a white shield, and two swords hung thereby, and two spears leaned there by a tree. And when Sir Launcelot saw the swords, anon he leapt to the one sword, and took it in his hand, and drew it out. And then he lashed at the shield, that all the meadow rang of the dints, that he gave such a noise as ten knights had foughten together.
