In recent years, exciting new discoveries of inscriptions and archaeological remains on the Arabian Peninsula have led to a re-evaluation of the peoples on the Arabian frontier, which through their extensive contacts with Rome and Persia are now seen as dynamic participants in the Late Antique world. The present volume contributes to this recent trend by focusing on the contrast between the 'outside' sources on the peoples of the frontier - the Roman view - and the 'inside' sources, that is, the precious material produced by the Arabs themselves, and by approaching these sources within an anthropological framework of how peripheral peoples face larger powers. For the first time, the situation on the Arabian frontier is also compared with that on the southern Egyptian frontier, where similar sources have been found of peoples such as the Blemmyes and Noubades. Thus, the volume offers a richly-documented examination of the frontier interactions in these two vibrant and critically-important areas of the Late Antique East. The book is of interest to anthropologists, archaeologists, historians, Egyptologists, Arabists, epigraphists and papyrologists and, in general, to all scholars working in the period of Late Antiquity.
