The public/private distinction is fundamental to modern theories of the family, religion and religious freedom, and state power, yet it has had different salience, and been understood differently, from place to place and time to time. The volume brings together essays from an international array of experts in law and religion, in order to examine the public/private distinction in comparative perspective. The essays focus on the cultures and religions of the ancient Mediterranean, in the formative periods of Greece and Rome and the religions of Judaism, Christianity and Islam. Particular attention is given to the private exercise of religion, the relation between public norms and private life, and the division between public and private space and the place of religion therein.
