The thoughts and beliefs of the Stonehenge people are unquestionably the most impenetrable of all the mysteries that this book will touch upon. Some prehistorians claim that nothing can be known of the beliefs of a long-dead people without writing. Although no documents, creeds or philosophical utterances survive, it is possible to see in the monuments and inscriptions assertions of a committed and deep-seated belief. A quest for a great lost faith must be worth attempting, even if, in the end, the most potent secrets are kept from us. I believe that, by assembling what seem to be the most ancient European mythic traditions and testing whether they mesh together to make a coherent religious philosophy consistent with the archaeological evidence, it will be possible to reach closer than ever before to the deepest aspirations of the builders of Stonehenge.
