In the Cymro-Latin prose romance Arthur and Gorlagon (early fourteenth century), Arthur's queen tells him that he does not know the nature or the heart of a woman. Challenged by her, Arthur goes on a quest to find an answer. He comes upon a town that belongs to a king Gorgalon (or Gargol). Arthur tells him that he wishes to learn "what are the heart, the nature, and the ways of women." Gorgalon answers him by telling the story of a king (Gorgalon himself) who is turned into a werewolf by his lecherous, traitorous wife.
