The paper explores the cultural components of Late Roman military equipment through the examination of specific categories: waist belts, helmets, shields and weaponry. Hellenistic, Roman, Iron Age European, Mesopotamian- Iranian and Asiatic steppe nomad elements all played a part. The conclusion is that the whole history of Roman military equipment involved cultural inclusivity, and specifically that Late Roman equipment development was not some new form of ‘degeneration’ or ‘barbarisation’, but a positive acculturation.
