Saint Flavitus was a priest and hermit who lived during the early Middle Ages. Born in mid-6th century Lombardy, he was later taken as a prisoner of war in Champagne in 568. During his time there, he served as an intendant for a castle, where he reportedly healed the family of his master from sickness. Following his ordination as a priest by Saint Lupus, he chose to live a life of solitude in Marcilly-le-Hayer until his death in 630.
