Prof. Jones' book examines the associations of ancient Athens under the classical democracy (508/7-321 B.C.) in light of their relations to the central government. Associations of all types--village communities, cultic groups, brotherhoods, sacerdotal families, philosophical schools, and others--emerge as fundamentally similar instances of Aristotelian koinoniai. Each, it is argued, acquired its distinctive character in response to particular features of the contemporary democracy. The analysis results in the first integrated, holistic institutional reconstruction of Greece's first city.
