This volume publishes records 66 diplomas or fragments which provide vital evidence for the Roman military and legal world. It is the third volume of a set of four created by Roxan.

Roman Military Diplomas V presents 154 diplomas, and incorporates them into the updated chronologies witness lists and indexes which are a key part of the Roman Military Diplomas series. A few of the diplomas were prepared by the late Margaret Roxan and some others were found after her death in preparation. Otherwise, the intention has been to bring together diplomas published by the end of 2003. But the large number included in this volume also reflects the active interest of collectors and the results of metal detecting. The lively market in diplomas has, however, also had less benign consequences and the volume has an important appendix on the production of fakes. The volume continues Margaret Roxan's Roman Military Diplomas 1954-1977 (1978), 1978-1984 (1985) and 1985-1993 (1994) which were published as Occasional Papers of the Institute of Archaeology University of London, and Roman Military Diplomas IV (2003) which was published by the Institute of Classical Studies as BICS Supplement 82. RMD IV and RMD V follow the format and continue the numbering of the diplomas and the pagination of the previous volumes.

This classic work of scholarship scrutinizes all aspects of Roman military forces throughout the Roman Empire, in Europe, North Africa, and the Near and Middle East. Graham Webster describes the Roman army’s composition, frontier systems, camps and forts, activities in the field (including battle tactics, signaling, and medical services), and peacetime duties, as well as the army’s overall influence in the Empire. First published in 1969, the work is corrected and expanded in this third edition, which includes new information from excavations and the finding of contemporary scholars. Hugh Elton provides an introduction surveying scholarship on the Roman army since the last edition of 1985.

This volume presents 121 complete and fragmentary diplomas ranging in date from AD 61 to AD 245. 69 of these diplomas have not previously been published. These and most of the published diplomas had been worked on by Margaret Roxan. Nine have been prepared by Paul Holder who has also standardized entries and updated references and notes where necessary. Among the appendixes and indexes are a new 'Revised chronology of diplomas' and updated witness lists. This volume continues Margaret Roxan's Roman Military Diplomas 1954-77 (1978), 1978-84 (1985) and 1985-93 (1994) which were published as Occasional Papers (Nos 2, 9 and 14) of the Institute of Archaeology, University of London. This new volume, volume IV, follows the format and continues the numbering of the diplomas and the pagination of the preceding volumes.

This Companion is the first of its kind on the Roman historian Cassius Dio. It introduces the reader to the life and work of one of the most fundamental but previously neglected historians in the Roman historical cannon.
