Arnobius of Sicca (died c. 330) was an Early Christian apologist, 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.
