Saint Vigor was a 6th-century bishop from Artois who served as a missionary in France. After studying under Saint Vedast in Arras, he left his noble home alongside an acolyte named Theodimir to live as a hermit preacher in Reviers. He eventually became the bishop of Bayeux around 514. Known for his efforts to convert people from paganism, he established a monastery at Saint-Vigor-le-Grand and constructed a church on the site of a former pagan temple.
