Roland was a popular legendary figure in medieval Europe. Over the next several centuries, Roland became a "pop icon" in medieval minstrel culture. According to many legends, he was a nephew of Charlemagne (whether or not this was true we do not know), turned his life into an epic tale of the noble Christian killed by Islamic forces, which forms part of the medieval Matter of France. Roland's tale is retold in the eleventh century poem The Song of Roland, where he is equipped with the Olifant (a signalling horn) and an unbreakable sword, enchanted by various Christian relics, named Durendal. The first story written about him was Orlando Innamorato by Matteo Maria Boiardo. After his death, the epic was continued as Orlando furioso by Ludovico Ariosto (See below for his later history in Italian verse).
