The importance of oaths to ancient Greek culture can hardly be overstated, especially in the political and judicial fields; but they have never been the object of a comprehensive, systematic study.This volume derives from a research project on the oath in ancient Greece, and comprises seventeen chapters by experts in law, in political and social history, in literary criticism, and in cross-cultural studies, exploring the subject from a broad spectrum of positions. Topics covered include the nature of ancient Greek oaths; the functions they performed within communities and in relations between them; their exploitation in literary texts and at critical moments in history; and connections between Greek oath phenomena and those of other cultures with which Greek came into contact, from the Hittites to the Romans.
