The inscribed text referred to as the sacred law of Andania contains almost 200 lines of regulations about a mystery festival and the sanctuary in which it took place. This book presents a new edition of the inscription and examines its rules in the wider context of Greek religious law and the management of sacred space. The regulations touch on a range of issues including finance, pollution, and the role of women, so that this study can be used as a handbook on the daily life of Greek religion.
