Gennadius. Lives of Illustrious Men 85

Prosper of Aquitania, a man scholastic in style and vigorous in statement, is said to have composed many works, of which I have read a Chronicle, which bears his name, and which extends from the creation of the first man, according to Divine Scripture, until the death of the Emperor Valentinianus and the taking of Rome by Genseric king of the Vandals. I regard as his also an anonymous book against certain works of Cassianus, which the church of God finds salutary, but which he brands as injurious, and in fact, some of the opinions of Cassian and Prosper on the grace of God and on free will are at variance with one another. Epistles of Pope Leo against Eutyches, On the true incarnation of Christ, sent to various persons, are also thought to have been dictated by him.
