For even the casual observer (such as myself) there's something about stone circles that inspires awe and yet they remain a curiosity. Their true significance has little impact on us today. Sadly, at first glance they look like primitive things fashioned into simple worshiping sites by primitive ancestors who left no records. Nothing could be simpler than a few unhewn stones arranged in a simple circle, could it? But let us consider a few facts. Firstly, the stone circles are often just one part of a large complex that includes other types of ancient construction, some now destroyed. In the case of Avebury, the whole landscape for miles around has other sites that are linked to it, including our very own Great Pyramid, the artificial Silbury hill. In fact, Western Europe is covered in circles and barrows and many of them required extraordinary organisation of manpower and exactitude of design. So far you may be thinking, so what? But the stones are not arranged wily-nilly, or to look pretty, but incorporate mathematical forumalae, are carefully and knowledgeably positioned (Avebury is apparently exactly three sevenths north of the equator) and align with moon and sun rises at key times. And probably much more. They were also built over thousands of years, so it seems that this culture endured long enough to deserve a bigger mention than it gets in the history books. Could it be that before recorded history our ancestors knew that the Earth tilted at 23.4 degrees on its axis? And hence, I suppose, that it was spherical). Did you know about the Michael line? Or that the waterboard still use dowsers?
This book in an excellent introduction to Avebury for anybody who just knew of it as a decent alternative to Stonehenge. Where it fails is in a clear explanation of some of the geometry. In particular, I cannot fathom how the Great Pyramid is linked to the site, though there is a diagram. It also fails in the sense that no book can really uncover the mysteries of Avebury but speculate. There is a clear sense of this being somewhat slender but I believe it reasonably fulfills its mandate.
