Third-century bishop
Peregrine (Peregrinus) of Auxerre is venerated as the first bishop of Auxerre and the builder of its first cathedral. A strong local tradition states that he was a priest of Rome appointed by Pope Sixtus II to evangelize this area at the request of the Christians resident in that part of Gaul. He preached at Marseille, Lyon, and converted most of the inhabitants of Auxerre to Christianity.
