Did Atlantis really exist? If so, where? The authors present a thesis that there was an ancient continent, that it housed a very sophisticated civilization, that its existence was known about and for various reasons suppressed, that myths from all over the world preserve a remarkably consistent description of what happened to it, and that the true story of lost Atlantis explains many key conundrums about life on this planet. Inspired by catastrophe theory (in particular the pattern and effects of earth-crust displacement), as well as ancient maps showing remarkably accurate delineation of land-masses, the corroborative content of myth from tribal American Indians to Plato - and further encouraged by the discovery that the Sphinx is much older than previously thought - the authors give every impression of having solved the mystery of Atlantis. Through a series of explanations of climatic changes, extinctions, migrations, standing stones and other ancient monuments, the authors pin-point where they believe Atlantis was.
