Seeking to unravel the various interpretations of Atlantis and its kindred myths of Lemuria and Mu, Professor Joscelyn Godwin shows how the legends of Atlantis go hand-in-hand with the concept of cyclical history, such as the Vedic system of the four Yugas, the Mayan calendar with its 2012 end-date, the theosophical system of root races, and the precession of the equinoxes. This study thoroughly reviews the rationalist and occultist writings on Atlantis including the work of G. I. Gurdjieff, Julius Evola, Edgar Cayce, Dion Fortune, and Rene Guenon. It also examines the related topics of reincarnation, human evolution, the origins of race, and catastrophe theory.
