The priests of ancient Egypt preserved a geometrical canon, a numerical code of harmonies and proportions, that they applied to music, art, statecraft, and all the institutions of their civilization. Plato, an initiate in the Egyptian mysteries, said it was the instrument by which the ancients maintained high, principled standards of civilization and culture over thousands of years. In The Dimensions of Paradise, John Michell describes the results of a lifetime's research, demonstrating how the same numerical code underlies sacred structures from ancient times to the Christian era. In the measurements of Stonehenge, the foundation plan of Glastonbury, Plato's ideal city, and the Heavenly City of the New Jerusalem described in the vision of Saint John lie the science and cosmology on which the ancient world order was founded. The central revelation of this book is a structure of geometry and number representing the essential order of the heavens and functioning as a map of paradise.
