syn/trd/late Iron Age to end of Roman period
"Résumé: The evidence that pottery provides for trade and contact across the Channel between the late Iron Age and the end of the Roman period is reviewed. The problem of distinguishing between the regional and long distance stimuli to cross-Channel traffic is discussed. Quantitative studies of imported wares as a proportion of complete pottery assemblages will help to resolve this mailer. The regional pattern becomes clearer in the late Roman period when long distance traffic is of less importance. Quantitative studies of BB1 and Oxfordshire ware allow us to distinguish two main areas of contact in the later Roman period. On the one hand there is evidence for important links between central southern England and eastern Brittany and western Normandy; on the other, the evidence of Oxfordshire ware, Argonne ware and Eifelkeramik demonstrates the role of short crossings between the mouth of the Rhine and Boulogne and east Kent and the Thames estuary, including London. In general we probably underestimate the importance of the links between north-western France and southern and south-eastern England in the Roman period." In short, an up-dated and boiled-down version, in French, of the author’s paper in Peacock (ed.), Pottery and Early Commerce, 1977.

A substantial paper on the distribution of roller-stamped Argonne samian in north-western Gaul, particularly Brittany, Normandie and Picardie, but Britain is also included in two general distribution maps. There is a set of eight maps of north-western Gaul showing the comparative proportions of each of the eight roller-stamp types defined by Hiibener (Banner Jahrbucher, 168, 1968, 241-298; illustrations of the eight group types, with their respective proposed dating, appear earlier in the same SFECAG volume, in entry no. 1203, 163). There is also a set of seven maps showing the distributions respectively of the seven most important Argonne workshops, viz, Lavoye, Châtel-Chéhery, les Allieux, Vauquois, Pont-des-Quatre-Enfants, Avocourt and Aubréville. A total of 120 roller-stamped sherds or stamps on their own are illustrated from sites in Normandie, and there are several tables showing the numbers of examples recorded at a wide range of sites.
   The authors point out that particularly after the late 4th century roller-stamped Argonne ware is virtually the only good dating evidence for many sites, since dateable coins are thereafter very rare. This means that the thirty-year periods established by Hubener for his successive types can only be a rough guide, and while there have been some criticisms of the Hubener system, it remains all there is. This paper is a considerable contribution to the subject.

This paper follows on from Mme Simon-Hiernard's book on pottery in the Musée de Poitiers (JRPS 4, entry no. 1005) by re-examining and taking a broader view of the most significant pottery type highlighted in that work, marbled wares from western France. While retaining (and re-printing) the typology established by Raimbault (Gallia 31, 1973, 185-206), this study looks in detail at the distribution of Aquitanian marbled wares, showing that they are found in highest concentration in Charente-Maritime, to the west and north of Poitiers. Although one outlier is noted from Switzerland, the bulk of the wares are found to the west of Paris, from the valley of the Gironde to the south to the Severn Valley in Britain, to the north. Simon-Hiernard's map indicates almost as many findspots in Britain as in Normandy and Brittany, and a remarkably high proportion of the findspots, even those in Charente-Maritime, are either on the coast or on rivers. One cannot usually say that an individual vessel must have travelled by water or by land to reach its destination, and of course most major settlements are linked to the rest of the world by both waterways and roads, but this map does certainly suggest a predominance of water transport for marbled wares. There is not much doubt about the finds from Britain and the Channel Islands.
