 According to that "vita", he was the bishop of Saint-Pol-de-Léon in the seventh century, after having acquired a reputation as an ascetic and anchorite whose prayer and presence cured people and had helped fight off a Viking invasion.When he was elected as bishop, he tried to avoid that responsibility by going to Rome; after intervention by Pope Gregory I he returned and served for over a decade.He died in Rennes (on the other side of Brittany from Saint-Pol-de-Léon), where he was buried in the cathedral.
