This book contains a wide-ranging discussion of the literature of religious apologetic composed by pagans, Jews, and Christians in the Roman empire up to the time when Constantine declared himself a Christian. The contributors are distinguished specialists from the fields of ancient history, Jewish history, ancient philosophy, New Testament studies, and patristics. Each chapter is devoted to a particular text or group of texts with the aim of identifying the literary milieu and the circumstances that led to this form of writing. When appropriate, contributors have concentrated on whether the notional audience addressed in the text is the real one, and whether apologetics was regarded as a genre in its own right.
