Ansbert was born at Chaussy-sur-Epte, a village in the Norman historical area known as the Vexin. He was born to a noble family, and was highly educated. He had a significant professional career, and is said to have served as a senior member of the court of the Merovingian king, Clotaire III. As such, he was both Lord Chancellor of France and Référendaire of France. Ansbert was engaged to be married to another future saint, Angadrisma. Her father, said to have been another of Clotaire's chancellors, arranged for her to wed his colleague, but Angadrisma – later a patroness of nuns – prayed for release from this obligation. Tradition states that dispensation was given to her after she was "struck down with leprosy", a disfiguring malady which only disappeared when she joined a convent. Some sources state that Ansbert later took a different bride.
Religious vocation
In 673, the same year Clotaire died, Ansbert renounced his secular pursuits and became a monk of the Benedictine order. Six years later, he was elevated to abbot of his monastery, the illustrious Fontenelle Abbey. He followed two other saints in that office: Wandrille, the abbey's founder and first abbot, and Lambert, the second abbot, who vacated the office when he was named bishop of Lyons. Under his leadership, Fontenelle prospered. His enterprises included a great expansion and refinement of the abbey's library, and the establishment of local hospitals for the poor. During his time as abbot, Ansbert served as the confessor to King Theodoric III. After several years, Ansbert was appointed archbishop of Rouen following the death of the previous officeholder, Saint Ouen, in 683 or 684. His former mentor Saint Lambert performed his consecration, and Ansbert was succeeded as abbot at Fontenelle by Hildebert, who is also venerated as a saint. Despite his high office and eminent reputation, Ansbert was removed from the bishopric around the year 690. By "a false accusation", the powerful majordomo of the Frankish court, Pepin of Heristal, arranged his dismissal, either because of some kind of political opposition or because Ansbert's "zeal was not well-received" and "his austere life caused offence". He was sent into exile at the monastery of Hautmont where he stayed until his death, sometime between 692 and 695. At some time Pepin apparently reconsidered his actions and agreed to allow Ansbert to return, but either he changed his mind again or Ansbert died before making the trip.
Legacy
The 12th-century chronicler Ordericus Vitalis relays a tale in which it was said that Ansbert's remains were desecrated and dispersed by soldiers of Hugh the Great. He asserts that the bones in question belonged to a different Ansbert, and that those of the saint were, at the time of his writing, still preserved safely at Fontenelle Abbey. The 18th-century author Alban Butler, however, states that the remains were at some point transferred to St. Peter's Abbey in Ghent, where they were destroyed by Calvinists in 1578. A collective day of remembrance for all the many saints associated with Fontenelle Abbey is celebrated on 1 March. Saint Ansbert's own annual feast day is 9 February.
