Court official

He was part of a group of young courtiers like Wandrille and Didier of Cahors and was a close friend of Eligius, whose vita he wrote. He and Eligius served as royal envoys to persuade Amadus to baptize Dagobert's son. According to Ian Wood, "...Audoin and Eligius were arguably the most influential churchmen in Francia during the seventh century."^[6]

In 634 Audoin was ordained priest by Dieudonne, Bishop of Mâcon. The following year, he and his brothers Ado and Rado founded Rebais Abbey, on land donated by King Dagobert. Audoin appointed his relative, Agilus, as first abbot. He also took part in the founding of Saint-Wandrille monastery in Rouen, and a nunnery at Fécamp. Fredegar reports that even as court referendary, Audoin had a reputation of being a religious man.^[7] He spent a year as a missionary in Spain, during which a drought was ended through his prayers

Bishop

In 641 he succeeded Romanus as bishop of Rouen.^[5] Through his influence, Erchinoald donated to Wandregisel the land for Fontenelle Abbey in Normandy. He developed theological studies and participated in the fusion of the rule of Saint Colomban and that of Saint Benedict.

During the regency of Queen Bathilde, Audoin became one of the first counsellors of the queen. He was an advisor of Theuderic III and upheld the policy of Ebroin, the mayor of the palace, to such a degree that he was involved in the mistreatment of Leodegar. The bishop's position was strengthened when Theuderic confirmed to him the right to elect and approve the Count of Rouen.

Around 675 Audoin made a pilgrimage to Rome. There he visited the sanctuaries, distributed alms to the poor of Rome, and collected relics to bring back to Rouen. After Ebroin's death in 681, he went to Cologne and succeeded in restoring peace between Neustria and Austrasia, but died shortly thereafter at the royal villa at Clichy on 24 August 684. He was buried in the Church of Sant-Peter which he himself had built. The former abbot of Fontenelle, Ansbert, succeeded Audoin as Bishop and had his predecessor reburied behind the high altar, the equivalent of a canonization.

Audoin wrote a vita of his friend, Eligius. This biography, which is one of the most authentic historical monuments of the seventh century, contains a store of valuable information regarding the moral and religious education of that time, and also testifies to the life of Aurea of Paris.^[8][9]

A poem on Audoin's life was written in the tenth century by Frithegod, but it is now lost.^[10] The author of the Liber Historiae Francorum, thoroughly hostile to the memory of Ebroin, invariably referred to Audoin as "blessed" or "sainted", and in describing his death said he "migravit ad Dominum", a phrase he otherwise reserved in the original part of his history for the death of the "glorious lord of good memory, Childebert III, the just king".^[11]
