Book XII - Chapter X - How Sir Launcelot with Sir Percivale and Sir Ector came to the court, and of the great joy of him.
THEN they departed, and within five days' journey they came to Camelot, that is called in English, Winchester. And when Sir Launcelot was come among them, the king and all the knights made great joy of him. And there Sir Percivale de Galis and Sir Ector de Maris began and told the whole adventures: that Sir Launcelot had been out of his mind the time of his absence, and how he called himself Le Chevaler Mal Fet, the knight that had trespassed; and in three days Sir Launcelot smote down five hundred knights. And ever as Sir Ector and Sir Percivale told these tales of Sir Launcelot, Queen Guenever wept as she should have died. Then the queen made great cheer. O Jesu, said King Arthur, I marvel for what cause ye, Sir Launcelot, went out of your mind. I and many others deem it was for the love of fair Elaine, the daughter of King Pelles, by whom ye are noised that ye have gotten a child, and his name is Galahad, and men say he shall do marvels. My lord, said Sir Launcelot, if I did any folly I have that I sought. And therewithal the king spake no more. But all Sir Launcelot's kin knew for whom he went out of his mind. And then there were great feasts made and great joy; and many great lords and ladies, when they heard that Sir Launcelot was come to the court again, they made great joy.
