An oblate of the abbey of Saint-Germain d'Auxerre, he studied with Lupus Servatus and Haimo of Auxerre.
Other works include his Collectaeum,[2] a homiliary, and glosses on the Categoriae decem.
From 859 to 860 he studied under Lupus Servatus at Ferrières, and from 862 to 865 he was at the abbey of Saint-Médard de Soissons, where he came into contact with John Scotus Eriugena.
His chief work was a metrical Life of Germanus of Auxerre, considered one of the best hagiographical poems of the times, which he dedicated c. 876 to Charles the Bald.
He is important as a link between the Carolingian schools and the later Middle Ages, especially as the teacher of Remigius.
