Who Lactantius was
An African pupil of the rhetorician Arnobius, Lactantius held the imperial chair of Latin rhetoric at Nicomedia — and was sitting in Diocletian’s capital when the Great Persecution was proclaimed in 303. He resigned or was dismissed, wrote through the terror, and lived to tutor Constantine’s son Crispus at Trier. His Divine Institutes, seven books in the smoothest Ciceronian Latin, are the first full presentation of Christianity to the Roman educated class — including antiquity’s most ringing argument that religion compelled is no religion at all. On the Deaths of the Persecutors, written after 313, is the eyewitness pamphlet through which we know the persecution’s inside politics, Constantine’s dream before the Milvian Bridge, and the text of the Edict of Milan.
