A full career of Ogier from youth to death is treated in "La Chevalerie Ogier de Danemarche", a 13th-century assonanced poem of approximately 13,000 lines attributed to Raimbert de Paris. It relates Ogier's early years, his rebellion against Charlemagne and eventual reconciliation. This is now considered a retelling. Ogier in a lost original ""Chevalerie Ogier" primitive" is thought to have fought alongside the Lombards because Charlemagne attacked at the Pope's bidding, as historically happened in the Siege of Pavia (773–74), that is, there was no fighting with the Saracens (i.e. Muslims) as a prelude to this.
