What is "ansegisus"

Ansegisus (Latin form of the Germanic name Ansegis, French form Anségise) can refer to:

• Saint Ansegisus, abbot of Luxeuil Abbey and Fontenelle Abbey
• Ansegisel, Frankish duke and mayor of the palace
• Ansegisus of Sens, Archbishop of Sens

Saint Ansegisus (c. 770 – 20 July 833 or 834) was a monastic reformer of the Franks.

Born about 770, of noble parentage, at the age of eighteen he entered the Benedictine monastery of Fontenelle (also called St Wandrille after the name of its founder) in the diocese of Rouen. St Girowald, a relative of Ansegisus, was then Abbot of Fontanelle. Upon the recommendation of the Abbot St Girowald he was entrusted by the Emperor Charlemagne with the government and reform of two monasteries, St Sixtus near Reims and St Memius (St 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.
