The 21st Symposion of the International Society for Greek and Hellenistic Legal History took place in Tel Aviv on September 20-23, 2017. Sixteen papers were presented, and respondents opened the discussion after each paper. The papers and responses to the following issues are collected in this volume: archaic Greek law, law of classical Athens, epigraphic and literary evidence of legal practice from other poleis of Hellenistic and Roman times, as well as legal papyrus documents. The volume is dedicated to the memory of Joseph Mélèze Modrzejewski, co-founder of the 'Symposion' and its co-organizer since 1971. The meeting fosters on an international level the cooperation of legal historians with those studying all aspects of Classical Antiquity allowing the participants a free choice of topics from their current areas of research.
