Sommario/riassunto |
|
The Neolithic period, when agriculture began and many monuments - including Stonehenge - were constructed, is an era fraught with paradoxes and ambiguities. Starting in the Mesolithic and carrying his analysis through to the Late Bronze Age, Richard Bradley sheds light on this complex period and the changing consciousness of these prehistoric peoples. The Significance of Monuments studies the importance of monuments tracing their history from their first creation over six thousand years later. Part One discusses how monuments first developed and their role in developing a new sens |
