Did Atlantis really exsist? If so,where was it,and what happened to it? Inspired by the theory that at various stages in prehistory the earths crust shifted dramatically,causing violent earthquakes,tidal waves,devastating climatic changes,the authors examine the clues as to the location of Atlantis entrusted to Plato by Egyptian priests,the extraordinary similarities between myths from around the world,and ancient and amazingly accurate maps of South America and ice free Antarctica that date long before the first European explorers ever reached those shores.They conclude that a civilisation of highly intelligent seafarers did exists some twelve thousand years ago,but was destroy ed,by a geological disaster,leaving only a few survivors to safeguard its relicsand legends for posterity.
