The defeat of the Moors at Orange was given legendary treatment in the 12th century epic "La Prise d'Orange". There, he was made Count of Toulouse in the stead of the disgraced Chorso, then King of Aquitaine in 778. He is difficult to separate from the legends and poems that gave him feats of arms, lineage and titles: Guillaume Fièrebras, Guillaum au Court-Nez (broken in a battle with a giant), Guillaum de Narbonne, Guillaume d'Orange. These legends turn his wife into a converted Saracen, Orable later christened Guibourc.
