First printed in 1988, "Mysteries of Atlantis Revisited", took a scientific look at Edgar Cayce`s "readings" about past and future events. Edgar Cayce, America`s best known and best documented psychic, became famous for his diagnoses of individual`s ailments and suggestions for their cure. Some of his readings did refer to past earth changes, even mentioning the mythical lost land of Atlantis, and possible future earth changes. Using research techniques, not available when Cayce`s readings were given, the authors evaluated this information in the light of recent geological and archeological discoveries, including efforts to carbon date the Great Pyramid. St. Martins new edition contains all of the original material plus an update detailing discoveries made between 1988 and 1997 such as: evidence for an older age of the Sphinx an unopened, and up to now, unknown chamber in the Great Pyramid new discoveries in and around Bimini data indicating an increase in worldwide earthquakes of a magnitude greater than 7.0
