The mutual interaction of philosophy and Roman political and cultural life has aroused more and more interest in recent years among students of classical literature, Roman history, and ancient philosophy. In this volume, which gathers together some of the papers originally delivered at a series of seminars in the University of Oxford, scholars from all three disciplines explore the role of Platonism and Aristotelianism in Roman intellectual, cultural, and political life from the second century BC to the third century AD.
