This Companion provides a comprehensive overview of the major themes and topics pertinent to ancient Greek law. Many of the 22 essays, written by an international team of experts, cover procedural and substantive law in classical Athens, but significant attention is also paid to legal practice in the archaic and Hellenistic eras. The essays offer substantial evidence of legal practice in Crete and Egypt, as well as the intersection of law with religion, philosophy, political theory, rhetoric, and drama.
