Career
Street Girowald, a relative of Ansegisus, was then Abbot of Fontanelle. Upon the recommendation of the Abbot Street Girowald he was entrusted by the Emperor Charlemagne with the government and reform of two monasteries, Street Sixtus near Reims and Street Memius (Street Mange) in the diocese of Challons-sur-Marne, in which he was successful. In 817, Louis the Pious made him abbot of the famous Luxeuil Abbey, founded by Saint Columbanus as early as 590.
Finally, having also reformed Luxeuil, he was transferred in 823, after the death of Einhard, as abbot to Fontenelle, where he had begun his monastic life and which he reformed as successfully as the previous monasteries.
He was responsible for compiling a number of capitularies, a document of civil and ecclesiastical law.
