Crossing the Pomerium: The Boundaries of Political, Religious, and Military Institutions from Caesar to Constantine

A multifaceted exploration of the interplay between civic and military life in ancient RomeThe ancient Romans famously distinguished between civic life in Rome and military matters outside the city—a division marked by the pomerium, an abstract religious and legal boundary that was central to the myth of the city's foundation. In this book, Michael Koortbojian explores, by means of images and texts, how the Romans used social practices and public monuments to assert their capital's distinction from its growing empire, to delimit the proper realms of religion and law from those of war and conquest, and to establish and disseminate so many fundamental Roman institutions across three centuries of imperial rule.Crossing the Pomerium probes such topics as the appearance in the city of Romans in armor, whether in representation or in life, the role of religious rites on the battlefield, and the military image of Constantine on the arch built in his name. Throughout, the book reveals how, in these instances and others, the ancient ideology of crossing the pomerium reflects the efforts of Romans not only to live up to the ideals they had inherited, but also to reconceive their past and to validate contemporary practices during a time when Rome enjoyed growing dominance in the Mediterranean world.A masterly reassessment of the evolution of ancient Rome and its customs, Crossing the Pomerium explores a problem faced by generations of Romans—how to leave and return to hallowed city ground in the course of building an empire.
