The Bretons give the name of Bisclavaret to the werewolf, or werefox, which throws itself upon the hunter's horse and terrorizes it. The same thing is called Garwal by the Normans.
Appearance
Bisclavaret is supposed to be a wizard, and if in olden times an unknown lady offered food to the hunters at the moment the animal appeared she was thought to be a witch.
Story
Marie de France in her Lay of the Bisclavaret used the idea of a werewolf, and again in this case the animal has no savage instincts except against his enemies, a faithless wife and her perfidious lover.
