Maugris

Maugris or Maugis was one of the heroes of the "chansons de geste" and romances of chivalry and the Matter of France that tell of the legendary court of King Charlemagne. Maugis was cousin to Renaud de Montauban and his brothers, son of Beuves of Aygremont and brother to Vivien de Monbranc. He was brought up by Oriande the fairy, and became a great enchanter. He won the magical horse Bayard and the sword Froberge which he later gave to Renaud.
French texts.
The oldest extant version of the story of Maugris was the anonymous Old French "chanson de geste" "Quatre Fils Aymon" dating from the late 12th century. It tells the tale of the four sons of Duke Aymon (Renaud de Montauban, Guichard, Allard and Richardet), their magical horse Bayard, and their adventures and revolt against the emperor Charlemagne. 
From the 13th century on, other texts concerning Maugris were created; together with the original, these are grouped as the "Renaud de Montauban cycle". These poems are: "Maugis d'Aigremont" (story of the youth of Maugis), "Mort de Maugis" (story of the death of Maugis), "Vivien de Monbranc" (story of the brother of Maugis), "Bueve d'Aigremont" (story of the father of Maugis, Bueve d'Aigremont, brother to Girart de Roussillon and Doon de Nanteuil).
Italian texts.
Along with Renaud (as "Rinaldo"), Maugris, as "Malagi" or "Malagigi", is an important character in Italian Renaissance epics, including "Morgante" by Luigi Pulci, "Orlando Innamorato" by Matteo Maria Boiardo and "Orlando Furioso" by Ludovico Ariosto.
