De Viris Illustribus (Illustrious Men)

Firmianus, known also as Lactantius, a disciple of Arnobius, during the reign of Diocletian summoned to Nicomedia with Flavius the Grammarian whose poem On medicine is still extant, taught rhetoric there and on account of his lack of pupils (since it was a Greek city) he betook himself to writing. We have a Banquet of his which he wrote as a young man in Africa and an Itinerary of a journey from Africa to Nicomedia written in hexameters, and another book which is called The Grammarian and a most beautiful one On the wrath of God, and Divine institutes against the nations, seven books, and an Epitome of the same work in one volume, without a title, also two books To Asclepiades, one book On persecution, four books of Epistles to Probus, two books of Epistles to Severus, two books of Epistles to his pupil Demetrius and one book to the same On the work of God or the creation of man. In his extreme old age he was tutor to Crispus Cæsar a son of Constantine in Gaul, the same one who was afterwards put to death by his father.
