Then after the departing of King Ban and of King Bors, King Arthur rode into Carlion. And thither came to him, King Lot’s wife, of Orkney, in manner of a message, but she was sent thither to espy the court of King Arthur; and she came richly beseen, with her four sons, Gawaine, Gaheris, Agravine, and Gareth, with many other knights and ladies. For she was a passing fair lady, therefore the king cast great love unto her, and desired to lie by her; so they were agreed, and he begat upon her Mordred, and she was his sister, on his mother’s side, Igraine. So there she rested her a month, and at the last departed. Then the king dreamed a marvellous dream whereof he was sore adread. But all this time King Arthur knew not that King Lot’s wife was his sister. Thus was the dream of Arthur: Him thought there was come into this land griffins and serpents, and him thought they burnt and slew all the people in the land, and then him thought he fought with them, and they did him passing great harm, and wounded him full sore, but at the last he slew them. When the king awaked, he was passing heavy of his dream, and so to put it out of thoughts, he made him ready with many knights to ride a-hunting. As soon as he was in the forest the king saw a great hart afore him.
