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.
