With the exception of stamped, red-slipped wares from the Argonne region of France, pottery imported from the Continent into late Roman Britain has received little attention. The object of this paper is to define and describe some types in Britain which appear to have originated in Germany. The vessels were first recognised during preparation of reports on Roman pottery from the Wallbrook, London, and Portchester Castle, Hampshire, and the closest parallels were to be found in the Rhineland. Petrological examination of these sherds in thin section and by heavy mineral analysis has defined two main categories of fabric, which accord geologically with the postulated origin. Further research in site- and museum-collections indicated the chronological and geographical distribution of these types in England: stratigraphical evidence, where available, points to a fourth-century date for importation, although in the Rhineland many of the forms originated in the late second and third centuries.
