We start with a review of Plato's popular story about an advanced civilization far to the West of the Pillars of Hercules - Atlantis.  But there are other theories as to Atlantis's location and if it ever existed!  We'll explore the conflicting theories and look at some alternative sites.  Importantly, we'll look at an American, "The Sleeping Prophet" Edgar Cayce, and his early 20th century prophecy of discovery, decades later, off Island of Bimini in the Caribbean.  Destination - the Unknown!
