(d'Agaune was born about A.D. 460, but the date of his death is unknown.: He became a monk in the convent of Agaune, in Valois, and in 505 went to Paris with Severinus, his abbot, who was called thither by Clovis I to employ his medical skill in treating him for a chronic fever. On his return journey Severinus died, and Faustus, who had remained in France, was commissioned by Childebert to write his life. This work is commendable for its simplicity, exactness, and scant mention of miracles as wrought by its subject, in an age whose literature is replete with such marvels. The best edition is that by Mabillon in the Acta Sanctorum Ord. Sancti Benedicti (Paris, 1668-1710, 9 vols. fol.; reprinted at Venice, 1733, 9 vols. fol.). The Acta Sanctorum assigns the 11th of February to St. Faustus d'Agaune.- Hoefer, Nouv. Biog. Gener. 17:202.
