[Now called Moutier-Saint-Jean, in Burgundy.] He was a native of the diocess of Langres, and took the monastic habit at Lerins. He was called into his own country by the bishop of Langres to found the abbey from which he received his surname. He settled it under the rule of Saint Macarius, governed it many years with great reputation of sanctity, and was rendered famous by miracles. He went to God about the year 540, being almost one hundred and twenty years old, and was one of the holy institutors of the monastic state in France. Saint Gregory of Tours gives an account of him in the eighty-seventh chapter of his book, on the glory of Confessors. His life was also compiled by Jonas, the disciple of Columban, extant in Bollandus.
