A collection of papers with new insights on ancient religion, read at a colloquium in honour of Professor H.S. Versnel ("Inconsistencies in Greek and Roman Religion"). The contributions, presented by nine leading scholars in the field, cover many areas of the religious experience of the Greeks and Romans: myth and ritual (W. Burkert), the gods (F. Zeitlin), cult, festivals, sacrifice. Several papers consider methodological problems and the progress of scholarship; they highlight the contribution of H.S. Versnel to the field. The papers are based on a wide range of sources: pagan and Christian, literary and epigraphical and iconographical. The collection will fascinate all scholars interested in ancient religion, whether they study malign magic, the Imperial cult or general theory.
