And then he knew well that he lay not by the queen; and therewith he leapt out of his bed as he had been a wood man, in his shirt, and the queen met him in the floor; and thus she said: False traitor knight that thou art, look thou never abide in my court, and avoid my chamber, and not so hardy, thou false traitor knight that thou art, that ever thou come in my sight. Alas, said Sir Launcelot; and therewith he took such an heartly sorrow at her words that he fell down to the floor in a swoon. And therewithal Queen Guenever departed. And when Sir Launcelot awoke of his swoon, he leapt out at a bay window into a garden, and there with thorns he was all to-scratched in his visage and his body; and so he ran forth he wist not whither, and was wild wood as ever was man; and so he ran two year, and never man might have grace to know him.

How Dame Elaine was commanded by Queen Guenever to avoid the court, and how Sir Launcelot became mad.
