This collection of essays explores the key issue of the nature of the boundary between fact and fiction, an issue which has become prominent especially through the upsurge of interest in the ancient novel and recent work on the rhetorical character of ancient historiography. The collection covers early Greek poetry (E.L. Bowie), Greek and Roman historiography (John Moles and T.P. Wiseman), Plato (Christopher Gill) and the Greek and Roman novel (John Morgan and Andrew Laird), and especially considers how far 'lying' was distinguished from 'fiction' at different periods and in different genres.
