Arnobius (died c. 330) was an early Christian apologist of Berber origin during the reign of Diocletian (284–305). According to Jerome's Chronicle, Arnobius, before his conversion, was a distinguished Numidian rhetorician at Sicca Veneria (El Kef, Tunisia), a major Christian center in Proconsular Africa, and owed his conversion to a premonitory dream. Arnobius writes dismissively of dreams in his surviving book, so perhaps Jerome was projecting his own respect for the content of dreams. According to Jerome, to overcome the doubts of the local bishop as to the earnestness of his Christian belief he wrote (c. 303, from evidence in IV:36) an apologetic work in seven books that St. Jerome calls Adversus gentes but which is entitled Adversus nationes in the only (9th-century) manuscript that has survived. Jerome's reference, his remark that Lactantius was a pupil of Arnobius and the surviving treatise are all that we know about Arnobius. Adversus nationes (Against the Pagans) was composed in response to Diocletian's persecution of Christians, and was a rebuttal to Pagan arguments as to why the persecution was justifiable. Arnobius, "a practitioner of the turgid and coarse style that is called African", is a vigorous apologist for the Christian faith, more earnest in his defence of Christianity than perfectly orthodox in his tenets. His book has been occasioned by complaints that the Christians had brought the wrath of the gods on Ancient Rome. Thus, he holds the heathen gods to be real beings, but subordinate to the supreme Christian God; in a streak of gnosticism, he affirms that the human soul (Book II, 14 - 62) is not the work of God, but of an intermediate being, and is not immortal by nature, but capable of putting on immortality as a grace. He even says that a belief in the soul's immortality would tend to remove moral restraint, and have a prejudicial effect on human life.
