Roman Imperial Constitutions preserved in Greek inscriptions and papyri (letters, edicts, subscripts, etc.) are indispensable sources for the history of the Roman Empire. Since the publication of Oliver's Constitutions, a considerable number of new documents has come to light, and the need for a complete index to the whole corpus is clearly apparent. This book provides a research tool for scholars interested in Greek epigraphy and papyrology, law and institutions, administrations and provincial diplomacy; it also illustrates the language variety of Greek used by the imperial chancellery. Words are given as they originally occur in documents, quoted in context and arranged according to formulas, common and distinctive expressions, or meaning. The book is supplemented by separate indices of personal names, peoples and places, emperors' names and titles.
