Fergus Millar's writings have helped to make the inhabitants of the Roman Empire central to our conception of how the empire functioned. He also has shown how and why Rabbinic Judaism, Christianity, and Islam evolved from within the wider cultural context of the Greco-Roman world. These 16 collected essays open with a contribution by Fergus Millar in which he defends the continuing significance of the study of Classics and argues for expanding the definition of what constitutes that field. In this volume he also questions the dominant scholarly interpretation of politics in the Roman Republic, arguing that the Roman people, not the Senate, were the sovereign power in Republican Rome. In doing so he sheds new light on the establishment of a new regime by the first Roman Emporer, Caesar Augustus.
