Stonehenge was not an observatory used by druidical astronomer-priests. It was, instead, a monument in which the moon and the sun and the dead were joined together. In this book the author explains how people in the British Isles, four thousand or more years ago, identified life and death with the cycle of midwinter and midsummer and with the risings and settings of the sun and moon. This is why so many megalithic monuments have astronomical sightlines built into them. This book describes how astronomical customs developed in the British Isles. Unlike other works about 'megalithic astronomy' technical explanations about azimuths and declinations are kept to their simplest. The emphasis here is upon people rather than pertrubations and eclipses.
