d. c.474. Priest and poet. Friend of * and brother of Mamertus, archbishop of Vienne, he was trained for monastic life and educated in Greek, Roman, and Christian literature. As assistant to his brother he trained clergy, organized services, and arranged the local psalter and lectionary. When published anonymously a treatise affirming that the soul is corporeal, Claudianus was urged by his friends to reply, and produced De Statu Animae in three books, which alone among his extant writings has theological value. Written between 467 and 472, it argues that a soul is incorporeal because it is made in the image of God and does not conform to the categories of place and quantity.
