This volume presents the proceedings of the fifth workshop of the international thematic network ́Impact of Empire ́, which concentrates on the history of the Roman Empire, c. 200 B.C. - A.D. 476, and, under the chairmanship of Lukas de Blois and Olivier Hekster (University of Nijmegen, The Netherlands), brings together ancient historians, archaeologists, classicists and specialists on Roman law from some 28 European and North American universities. The fifth volume focuses on the impact of imperial Rome on religions, ritual and religious life in the Roman Empire. The following topics are treated: connections between Roman expansion and religion, the imperial impact on local cults, cultic personnel (priests, priestesses and bishops), and the divinity of Roman Emperors.
