Reginald Hyatte translated the Romance of this person by Alexandre du Pont, which borrows from an Otia by Walter of Compiègne, alongside Bonaventure of Siena’s alleged French version of a book titled for this man’s ladder. Faria e Sousa’s commentary on the Lusiads identifies the giant Adamastor as representing this real-life person. In the Malebolge, Dante sees this man holding his chest open and his son-in-law’s face cleft (15[1])in two because of the (*) schisms they caused. In the Song of Roland, this man forms an “unholy trinity” with Apollyon and Termagant that is worshiped by King Marsile’s men. In order for Ruggiero to marry Bradamante in Orlando Furioso, he abandons a tradition founded by this man, which is followed by the antagonists of Torquato Tasso’s epic Jerusalem Delivered. For 10 points, the Divine Comedy may borrow from depictions of the Night Journey of what Islamic prophet? ■END■
