And after the tablecloths had been taken away and they had washed their hands, they went to stand at the windows and look up and down the marshes, and all around they could see the countryside that was so fair that it was no wonder they forgot themselves until it was time to go to bed. Then they went into a room next to the great hall where the maidens had prepared two beds that befitted such princes as they, and they went to bed with great rejoicing. And when the two kings had lain down, Merlin began to cast another spell, and all who were there went to sleep except King Ban and the young lady.
