he spread of Roman material culture in Britain in the decades before and after the Claudian invasion has long been an important field for scholars of Roman Britain. Two traditional concerns have been the supply of the Roman army and the distribution of Roman items to civilian and native populations 1 during this transitional and formative period. These areas have often been studied independently of each other. The examination of the supply and spread of material culture is valuable in its own right, but can contribute to our understanding of broader developments such as the impact on indigenous populations of Roman culture, the nature of the Roman economy, military organization, and Romanization. It is the intention of the current paper to outline and consider the incidence of one class of Roman artefact in a region of Britain and to demonstrate how the comparative study of such material may assist our understanding of social and economic developments in the first century A.D. The artefact type is pottery and the area of study is the eastern side of England from Leicester to Co. Durham. The perspective is chronological and comparative and it draws principally upon quantitative data. The current paper is derived from a wider study of the arrival and distribution of early Roman material culture into Britain. As part of that work the author looked at the composition of pottery groups from a range of sites occupied during the first century A.D. in the East Midlands, Yorkshire, and the NorthEast of England. 2 The presentation of some of these groups forms the principal subject of this paper. The pottery groups are arranged 1 e.g. S.D. Trow, 'By the northern shores of Ocean: some observations on acculturation process at the edge of the
