This sixth volume in the renowned Roman Military Diplomas series brings together in one accessible collection the Roman military diplomas published between 2004 and 2007. Each of the 179 diplomas is catalogued, transcribed and reconstructed alongside information relating to its physical description, findspot, state of preservation, current location and new readings helping to illuminate everything from the commanders of units to the social lives of soldiers. The volume also includes a revised chronology of the diplomas, appendices providing important criteria in dating the fragments, comprehensive indices of witnesses, persons, places and units and, for the first time, a table of concordances enabling concurrent work with previous volumes in the Roman Military Diplomas series. Collectively, the volume offers new insights into Roman military procedures and personnel, the social and legal status of soldiers and the afterlife of the diplomas. It is an essential reference tool for anyone researching Roman imperial history, the Roman army and epigraphy.
