Dear reader,      I wanted a kooky book that talked about ancient UFOs, Atlantis, and space cowboys from beyond the moon building the pyramids. You'd think a big book like "Ancient Mysteries" would deliver just that.      No such luck, instead what I got was a book discussing, but dismissing, crazy theories like Antarctica having been at the equator and the Earth's crust slipping to land it down in the Antarctic (note, this is the entire crust shifting all together, not continental drift). Their explanations for places like Atlantis, while probably not true, were inexcusably plausible. I didn't get a book that touts Edgar Cayce on the cover to read a reasonable guess speculating where Solon got his Atlantis story to pass along to Plato. And guess what? It doesn't involve space cowboys.      The best story was about a girl who hit her head when she was a kid and from then on believed she was a reincarnation of an ancient Egyptian priestess. Omm Seti, as she grew to be called, thought she was the illicit lover of Pharoh Seti 1 in a past life and was recieving spiritual visits from him in this life. The kicker? She became a respected Egyptologist and even with her known eccentricities, was aparently a quite beloved figure. I'm dying to read her biography, but I'll have to order it somehow to do it. (lackluster public library!)      All in all, "Ancient Mysteries" gets a rating of 8. 7 for the main part of the book; -1 for thoroughly confusing me on whether the original Greek was Heracles, Hercules, or neither; -5 for not being crazy, and +7 for having an erotic fanfic about a little English girl and a mummy.
