The Roman Army, 31 BC–AD 337 The Roman imperial army was unrivalled until recent times in its professional structure, efficient training, detailed organization, and ordnance support. It was remarkable in an age of poor communications and limited technological advance. The army sustained a great empire militarily and politically. First, its skill and success ensured Rome’s domination, and second the loyalty of the troops ensured the political survival of the emperors, who sought to preserve the fabric of government and make it work. The army was therefore a vital element in the subsequent development of Western Civilization. The large number of soldiers and their associated dependants meant that they had significant impact socially, economically, and culturally on the settlements that grew up round the camps and on some of the communitites where they settled after discharge. The privileges of the soldiers set them apart from other men of their social class, and the enhanced position of veterans established them as a very important group in their own right, an integral part of the whole phenomenon of Roman ‘government’. The study of the Roman army therefore embraces not only military but also political, social and economic history. This source book collects literary and epigraphic material, and papyri and coins which illustrate the varied aspects of army life both at war and at peace, and it takes account of evidence made available by recent archaeological investigations in many parts of the empire. Subjects covered include training, officers, the role of the emperor, fighting, community life, politics, and veterans. The introductions to each section and the linking passages provide a narrative structure and explain difficulties of the source material. This book will appeal to a wide audience: students of the army and the Roman empire, and all those interested in the ancient world and military studies.

In choosing material for this collection I have tried to illustrate not only military organization and practice but also something of the role of the soldiers in the social, political, and economic life of the empire. I have confined my attention to the imperial period since only then can we speak of ‘the’ Roman army; before, there were transient legions and then the various armies of military dynasts. Nevertheless, since the army of Augustus and his successors owed so much to the military practices of the Republic, I have included a brief introductory survey of the army before 31 BC. The changes made in the army by Diocletian and Constantine are a convenient stopping point, although there is a large body of evidence for post-Constantinian military developments. In presenting material I have used introductions and short commentaries to establish a narrative framework, primarily in cases where the sources are difficult or inadequate. In citing literary sources, I have given once in each section the dates of the author’s activity. In the case of inscriptions and papyri, I have included the find spot, the modern place-name where appropriate, the Roman province, and a precise date if possible, or an indication of the century, where this is pretty certainly known from internal evidence. In citing collections of inscriptions and papyri I have used the most accessible rather than the most recent, unless there are important new interpretations, and have sometimes included an alternative collection in addition to a basic work. As far as possible, papyri have been set out as the original editor transcribed the documents. John Curran, Raymond Davis, and Lawrence Keppie read parts of the text and made many useful suggestions; Walter Cockle patiently kept me informed about material from the Mons Claudianus xii Preface excavations; ] Margaret Roxan and Valerie Maxfield generously supplied photographs for some of the illustrations. I should like to thank all these scholars and exculpate them from responsibility for the author’s decisions and errors. I also thank my editor Richard Stoneman for so readily accepting this venture and for his subsequent guidance.
