Collected for the first time, these essays delve into the mysteries of the prehistoric human mind with intelligence, passion and a radical approach to the unknowability of the evocative but obscure early chapters of the human story. Starting from personal experiences with megalithic monuments and sites of ancient rock art, Gyrus unfolds implications and speculations that keep one eye on the latest academic research, the other on the unproven possibilities that intimacy with prehistoric relics affords. Also includes a foreword by acclaimed antiquarian, Julian Cope.
