And thence to the island of Cofus (Cos) and Longa (Lemgo) in which Hippocrates was born. And men say that in that island Hippocrates hath a daughter in form of a dragon, a hundred feet in length, and she lives in an old desolate castle, and the folk of that island call her the Lady of the Isle. She sheweth herself thrice every year, and she doth no harm to anyone unless he does harm to her, for when she was a damsel (the goddess) Diana put her into that form. And men say that she will remain thus until a knight shall come from the west of the World, and give a kiss to her mouth, and when she gets that kiss she will become a woman, and thenceforward she shall have only her own age. And it is not long since that a knight came from Rhodes and went with spirit and strength to give her a kiss, and rode on his courser to the place wherein she lay. But when he saw her he fled from her, and she followed him and took him against his will with her on the peak of a great rock, and (thence) cast him into the sea.
