Son of Duke Bevis of Aygremont, stolen in infancy by a female slave. As she rested under a white-thorn a lion and a leopard devoured her, and then killed each other in disputing for the infant. The babe cried lustily, and Oriande la Fée, who lived at Rosefleur, hearing it, went to the white-thorn and exclaimed, By the Powers above, this child is mal gist (badly lapped); and ever after he was called mau-gis. Oriande took charge of him, and was assisted by her brother Baudris, who taught him magic and necromancy. When grown a man Maugis achieved the adventure of gaining the enchanted horse Bayard, which understood like a human being all that was said, and took from Anthenor, the Saracen, the sword Flamberge or Floberge. Subsequently he gave both the horse and sword to his cousin Renaud. In the Italian romances Maugis is called Malagigi (q.v.).; Renaud is called Renaldo (q.v.); Bevis is called Buovo; the horse is called Bayardo; and the sword, Fusberta. (Romance of Maugis dAygremont et de Vivian son frère.)
