“ Guillaume, a foundling supposed to be of low degree, is brought up at the court of the emperor of Rome, and loves his daughter Melior who is destined for a Greek prince. The lovers flee into the woods disguised in bear-skins. Alfonso, who is Guillaume’s cousin and a Spanish prince, has been changed into a wolf by his step-mother’s enchantments. He provides food and protection for the fugitives, and Guillaume eventually triumphs over Alfonso’s father, and wins back from him his kingdom. The benevolent werwolf is disenchanted, and marries Guillaume’s sister. ”
