Considered the last of the "Five Good Emperors," Marcus Aurelius ruled the Roman Empire from ad 161 until his death in 180 – yet his influence on philosophy continues to resonate in the modern age through his Meditations. A Companion to Marcus Aurelius presents the first comprehensive collection of essays to explore all essential facets relating to contemporary Marcus Aurelius studies. Featuring contributions from top international scholars in relevant fields, initial readings provide an overview of source material by addressing such topics as manuscript transmission, historical written sources, archaeological evidence, artifacts, and coins. Readings continue with state-of-the-art discussions of various aspects of Marcus Aurelius – his personal biography; political, cultural, and intellectual background; and aspects of his role as emperor, reformer of administration, military leader, and lawgiver. His Meditations are analyzed in detail, including the form of the book, his way of writing, and the various aspects of his philosophy. The final series of readings addresses evolving aspects of his reception. A Companion to Marcus Aurelius offers important new insights on a figure of late antiquity whose unique voice has withstood the centuries to influence contemporary life.
