Robert Bauval was the first to truly begin to solve the Riddle of the Sphinx in his classic book, "The Orion Mystery." Since then, other prominent authors, including most notably Graham Hancock, have picked up the ball on the question of the Riddle of the Sphinx, focusing their efforts not only on defining what the Riddle means, but what its answer is. Inevitably, all come to the same conclusion, that the answer to the Riddle of the Sphinx is that the pyramids and Sphinx form a vast, three-dimensional treasure map, where X marks the spot on a mysterious Secret Chamber somewhere in the Giza necropolis. This chamber is believed to house an ancient Hall of Records which contains knowledge of the ancient world before the Flood, so naturally archaeologists, historians, and those interested in history in general are keen to discover the ancient Secret Chamber, if it truly exists. Bauval performs an admirable job of chronicling all the major and many of the minor players who have taken part in the quest for the Hall of Records, though I would have preferred more revelations concerning the current search for the Hall. Unfortunately, the recent lockdown by the Egyptian government on additional archaeological research in the Giza plateau has made this impossible. So, rather than relying on speculation to fill out a new book on the subject, Bauval decided to pause and chronicle all the relevant research to this point, a decision that was not only necessary, but appropriate.
