About the author

Julius Firmicus Maternus was a Roman Latin writer and astrologer, who received a pagan classical education that made him conversant with Greek; he lived in the reign of Constantine I (306 to 337 AD) and his successors. His triple career made him a public advocate, an astrologer and finally a Christian apologist. The explicit, or end-tag, of the sole surviving manuscript of his De errore profanarum religionum ("On the error of profane religions") gives his name as Iulius Firmicus Maternus V C, identifying him as a vir clarissimus and a member of the senatorial class. He was also author of the most extensive surviving text of Roman astrology, Matheseos libri octo ("Eight books of astrology") written around 334–337. Manuscripts of this work identify him as "the younger" (iunior) or "the Sicilian" (Siculus). The lunar crater Firmicus was named in his honour. The Matheseos was dedicated to the governor of Campania, Lollianus Mavortius, whose knowledge of the subject inspired Firmicus, and whose encouragement supported him during the composition of this handbook.
