Claudianus, presbyter of the church at Vienne, a master speaker, and shrewd in argument, composed three books, On the condition and substance of the soul, in which he discusses how far anything is incorporeal excepting God.
[He wrote also some other things, among which are, A Hymn on Our Lord's Passion, which begins “Pange lingua gloriosi.” He was moreover brother of Mamertus, bishop of Vienne.] (See note.)
