The Canso was a reworking of a lost earlier Occitan epic history of the First Crusade written by one Gregory Bechada and commissioned by Bishop Eustorge of Limoges probably between 1106 and 1118.[3] Being based partially on eyewitness testimony, the Canso is as a source for the Occitan participation at Antioch.[3][4] It emphasises the feats of the knights of southern France and southern Italy, especially Gouffier de Lastours and the Normans under Bohemond of Taranto.[3] In its completed form it may have also told the story of Count Raymond IV of Toulouse, but he is not mentioned in the surviving fragment.[2]
