Keith Critchlow, an internationally-renowned scholar, has studied a wide range of Neolithic artefacts. In "Time Stands Still", he adopts a technique of cross-cultural comparison to uncover some previously unknown characteristics of the Neolithic people. He takes ancient temple-building manuals from Indian Vedic sources, for example, and applies them to British sites - with fascinating results. He examines Chinese pictographs for evidence of sighting instruments and scientific tools. Perhaps most significantly, he offers evidence that stone-carved spheres with regular mathematical symmetries, found in Scotland, pre-date Plato's writings on geometric figures by more than a thousand years. The remarkable findings of this groundbreaking book are just as important today as when the book was first published.
