This volume presents one hundred of the papers given at the Fifteenth International Congress of Roman Frontier Studies. Geographically the material ranges throughout the frontier regions of the Roman Empire from Britain to the Caucasus, the Low Countries to Upper Egypt, Spain to Jordan. The first section deals with individual frontier regions, fort and fortress sites, army units and related military matters a overall surveys of significant work carried out in Britain and Germany in the 1980s. The second section explores three more general themes: the relations between "Romans" and "natives" on the peripheral areas of the Empire, the realities of life in a frontier region, and the problems peculiar to desert frontiers.
