The seneschal (or steward) of King Eliadus of Sicily.
Marangoz fell in love with Eliadusís wife and murdered Eliadus during a hunt. He proposed to the queen, but she fled from him and secured herself in the castle of Monreal, which Marangoz besieged for almost 20 years.
Eventually, Eliadusís son, Floriant, arrived in Sicily with King Arthur and an army to lift the siege. Marangoz received assistance from Emperor Filimenis of Constantinople. After several battles, the opponents agreed to decide the war in single combat between Floriant and Marangoz. After losing his nose, an ear, and a hand in the fight, Marangoz surrendered and was executed.
