Arnobius of Sicca, in North Africa, was a Christian convert writing in the time of the Emperor Diocletian in the 3rd sentury AD. His most famous work, Against the Pagans, was written shortly after his conversion (c. AD 302), and is a brilliant defense of his new religion using arguments taken from the best of pagan learning. It demonstrates exactly the nature and intensity of the conflict between pagans and Christians at this period. This book, the first major study of Arnobius, deals fully with every important aspect of his life and writing and demonstrates his significant contribution to the final triumph of Christianity over its Graeco-Roman competitors.
