The Chanson d'Antioche is a chanson de geste in 9000 lines of Alexandrin in stanzas called laisses, now known in a version composed about 1180 for a courtly French audience and embedded in a quasi-historical cycle of epic poems inspired by the events of 1097–99, the climax of the First Crusade: the conquest of Antioch and of Jerusalem and the origins of the Crusader states.
