In common with other volumes in the Thames Through Time series, this account of the Thames Valley in the millennium and a half before the Roman conquest seeks to examine change in human society from a thematic point of view. The geographical and chronological framework for this volume is established in Chapters 1 and 2, but thereafter we have tried to get away from the traditional, somewhat artificial pigeon-holes of 'periods' 'ages' 'eras' and 'phases' to look much harder at how change in human society actually works. In a period when the 20th century has come to dominate secondary school history and much popular TV, the notion that the first foundations of modern society can be traced back more than 3000 years may seem a rather surprising proposition. But some fundamental patterns of settlement and landuse, political boundaries, human impact on the environment, and even the specific use and form of a few places can be traced back to late prehistoric times despite millennia of subsequent change - even though otherwise we may now have very little in common with those remote ancestors. Exploring these issues on a thematic basis should help us to gain a better understanding of how human society evolves and also of how people have altered their natural environment, providing a better long term perspective on what we are doing to the planet.

The site at Whitecross Farm, including timber structures located on the edge of the eyot, and a substantial midden and occupation deposit has been securely radiocarbon-dated to the late Bronze Age. The late Bronze Age artefact assemblages are suggestive of a high-status site, with a range of domestic and ritual activities represented. The bank of the Grim's Ditch earthwork was found to have preserved evidence of earlier settlement, dating to the Neolithic and Bronze Age, and a sequence of cultivation, including ard marks and 'cord-rig' cultivation ridges. Pottery and radiocarbon analysis dated the earthwork to the end of the late Iron Age or the early Roman period. A multi-period settlement, consisting of pits, a waterhole, postholes, gullies and field systems, was identified at Bradford's Brook, Cholsey. The main periods represented are late Bronze Age and Romano-British, while a small quantity of Saxon pottery indicates limited Saxon activity. A large pit containing late Bronze Age pottery, a cattle skull, waterlogged wood and plant remains, a complete loomweight and flint flakes has been interpreted as a waterhole. A series of radiocarbon dates were obtained for deposits within this feature. All three sites are discussed individually as well as within their local, regional and national contexts. Chapter 7 provides an overall discussion of later Bronze Age themes that have arisen through the excavation and analysis of these sites.

Excavations conducted between 1981 and 1986 in advance of gravel extraction in Gravelly Guy field, Stanton Harcourt, Oxfordshire, revealed archaeological evidence spanning from the Neolithic through to the Saxon period. Neolithic and early Bronze Age activity is represented by pit scatters and a series of ring ditches with associated burials. The Iron Age and early Roman periods witnessed the continuous development of a linear settlement, consisting of a dense area of pits, gullies, circular structures, four-posters and boundary ditches in the mid to late Iron Age phase and a series of rectilinear enclosures and unusual 'ramped hollows' and wells in the late Iron Age/early Roman period. Excavation of a section at the junction of the floodplain and the gravel terrace has also provided information regarding the changing land use and contemporary environment in the vicinity of the site. Gravelly Guy remains one of the most thoroughly excavated sites of this period in the Thames Valley. As well as the vast amount of structural evidence, the considerable quantities of artefacts and environmental information recovered, together with a series of ten radiocarbon dates, have resulted in a detailed study of the site, its position in the landscape and relationship to the contemporary archaeology of the surrounding area.

Excavations at Mount Farm revealed a long sequence of activity running from the early Neolithic to the early Saxon period. The most significant finds include early Neolithic pit deposits, a middle Neolithic oval barrow associated with a primary burial and a secondary Beaker burial, a timber post-ring, an earlier Bronze Age round barrow associated with Deverel-Rimbury secondary burials, a later Bronze Age waterhole and burnt mound, extensive remains of an Iron Age settlement and a well-preserved Anglo-Saxon well. This is an innovative report which approaches the site from a thematic perspective which highlights social, economic and environmental change over the long period during which the site was occupied.
