On March 22, 1993 Rudolf Gatenbrink used a remote controlled robot to explore the shafts originating in the Queens's chamber of the Great Pyramid. The robot's camera showed an image of what may be a 'stone slab door with copper handles' and speculation was the order of the day. With this backdrop in mind Robert Bauval and Adrian Gilbert have produced a thought provoking book that captured the imagination of anyone who has an interest in the Great Pyramid at Giza. When the book hit the shops in 1994 it was complemented by TV coverage explaining some of the theories put forward. A key aspect is a connection of the pyramids with the night sky and in particular the sky as it was several thousand years ago.The media interest was further boosted by Robert Bauval advertising in the press for items found in the Great Pyramid, brought to Britain, but lost. "The Orion Mystery" was reviewed in the Sunday Telegraph on 1st January 1995 complete with a photograph of a 'mysterious stone slab with copper handles'. I cannot help but feel the media interest in this book created conflicting messages at the time. I decided to take the plunge and find out what the excitement was about and was pleasently surprised. The duo have put together a well constructed piece of work but you must take your own view on the evidence presented. What the authors interpret may have been in the minds of the architect(s) is explained but is it sound in light of all the evidence available in the public domain? I can comment that if you read this book, your investigations, reasearch and reading will probably continue if only to disprove or further accept the ideas put forward by the authors.
