Reflet de l'occupation sur le plateau de Saint-André-de-l'Eure (Eure) du Ier siècle avant J.-C. au III è siècle après J.-C. (R.N. 154 - section nord)

Abstract

After ten years of development in the south of the Eure, preparatory works of archaeology hâve resulted in the constitution of a documentation collected in relatively homogenous conditions over almost 300 hectares (500 by the end of 2001). The areas concemed are located at random within a chosen study zone, for analysis of land occupation, because of its geographical and topographical cohérence. The representativity of data produced by this documentation is a known parameter. Thus, they come increasingly to constitute an objective sample illustrating the archaeological potential of their acquisition area. Such a sample provides a first interprétation of the data on the archaeological map. As far as the plateau of Saint- André-de-1' Eure is concemed, the number of sites recorded goes over one thousand, half of which resuit from aerial research. The exploitation of this mass of information concerns ail the protohistorical and historical eras. Indeed, a reasoned and quantified survey of the importance of the sites of the second Iron Age and Early Empire cannot be envisaged without taking into account the continuities and discordances preceding and following the era in question. This case study leads to surprising results at first sight, the most outstanding being the extremely late évolution of the development of territory concemed. The intégration of the results of study into a reflexion on wider geographical areas provides a first explanation. The acceptable hypothesis of a very late rise of the rural exploitation of the plateau is after ail quite simple. The whole area was very scarcely occupied before the foundation and the development of the city of Evreux. The development of the urban centre together with the rural sites could therefore be accounted for almost exclusively by the satisfaction of the needs of the local urban market. As to the implantation of Evreux, it could simply be resuit of the administrative and économie organization on a large scale, subséquent to the Augustan reforms'1'.

The last millennia history of detrital sedimentation in the Lower Seine Valley (Normandy, NW France): review

“…4A), palaeochannels (middle of the Ist century; Incarville site, Fig. 4B; Lepert and Paez‐Rezende, 2005; Lepert et al. , 2002) and several pits (Pont Audemer site) points to a probable slowdown or even a total cessation of sedimentation during the Gallo‐Roman period. The brownish clayey silts are attributable to the latest V‐VIth centuries in terminus post quem .…”
