At the frontiers of the Roman Empire, military settlements had a profound influence on local crafting traditions. Legions were not just fighting units - they contained a large number of craftsmen, and the fortress would have been a center of manufacturing activity. But can all developments in local craft and industry be seen as a result of the appearance of the Roman army? The ten papers in this volume focus on craft production in Roman Yorkshire, and the evidence for the role of the army in local manufacturing activities. Several papers examine broad questions surrounding the organization and scale of production in urban and rural areas. Others consider the local evidence for individual materials and production processes, including those associated with pottery, glass, copper alloys, non-ferrous metals, leather, jet, and building stone.
