Private associations organized around a common cult, profession, ethnic identity, neighbourhood or family were common throughout the Greco-Roman antiquity, offering opportunities for sociability, cultic activities, mutual support and a context in which to display and recognize virtuous achievement. This volume collects a representative selection of inscriptions from associations in Attica, Central Greece, Macedonia, Thrace, published with English translations, brief explanatory notes, commentaries and full indices. This volume is essential for several areas of study: ancient patterns of social organization; the organization of diasporic communities in the ancient Mediterranean; models for the structure of early Christian groups; and forms of sociability, status-displays, and the vocabularies of virtue.
