Didascalicon, Book IV: the order and number of the divine books
Chapter XIV. Which Scriptures are authentic
Of ours among the Greeks, Origen in the labor of the Scriptures surpassed both Greeks and Latins in the number of his works. Jerome indeed confesses that he selected six thousand of his books. Of all these, however, Augustine surpassed the labors by his talent and knowledge. For he wrote so much that day and night not only to copy his books, but even to read them carefully, no one is able. Other Catholic men also wrote many and notable works: Athanasius, bishop of Alexandria; Hilary, bishop of Poitiers; Basil, bishop of Cappadocia; Gregory the Theologian, also Gregory Nazianzen the bishop; Ambrose, bishop of Milan; Theophilus, bishop of Alexandria; John, bishop of Constantinople; Cyril, bishop of Alexandria; Pope Leo; Proculus; Isidore of Seville; Cyprian the martyr; Jerome the presbyter; Origen, whose writings the Church neither wholly refutes nor receives in all things; Orosius, Sedulius, Prudentius, Juvencus. Arator and Rufinus, who published many books and interpreted certain Scriptures. But since blessed Jerome in some points noted him concerning freedom of the will, we ought to hold what Jerome also held. Gelasius also made five books against Nestorius and Eutyches, and tracts after the manner of Ambrose. Likewise against Arius; he also made prefaces of the sacraments, and prayers and letters of faith. Dionysius the Areopagite, ordained bishop of the Corinthians, left many volumes of his talent. Likewise the Chronicles of Eusebius of Caesarea, and the books of his ecclesiastical history, although in the first book of his narration he was lukewarm, and afterwards wrote one book in praise and excuse of the schismatic Origen, yet because of the knowledge of individual matters which pertains to instruction, the Church does not altogether refuse them. Cassiodorus also, who wrote a quite useful work in the exposition of the Psalms. There are still many others, whose names I pass over here.
