Since 1993 Robert Bauval has been embroiled in the many controversies involving the search for the lost treasures of the pyramid builders and the quest for the legendary Hall of Records of Atlantis. The strange but true story that he unfolds implicates American business moguls, the prestigious National Geographic Society, several Ivy League universities, the Edgar Cayce Foundation, the Freemasons, Christian fundamentalists, Zionists, and the Egyptian government. In this fully updated edition of Secret Chamber, including new color photographs, Robert Bauval pursues his in-depth investigation of clandestine events at Giza and the role played by the controversial ex-Minister of Antiquities Dr. Zahi Hawass. What lies behind the mysterious doors at the end of the star shafts in the Great Pyramid? What do the mysterious inscriptions found behind the Gantenbrink door mean? What is the real purpose of the Relief Chambers and the red ochre "graffiti" in them? Who is behind the secretly tunnelling and excavating in these chambers, and why? Is there really a hidden Hall of Records from Atlantis beneath the Great Sphinx? Is the Great Pyramid just a tomb or does it serve a higher purpose involving a lost science of immortality? Why do the ancient texts ascribe the Pyramid's design to the supreme god of wisdom Thoth, the writer of the fabled Books of Hermes? Will the Great Pyramid prove to be the "missing link" to our true origins or a "metaphysical machine" to access the world beyond? Providing a firsthand account of the strange events that have taken place at the Giza plateau in the last three decades, Bauval reveals the hidden agendas behind these events and raises important questions about the meaning of Egypt's ancient structures and the very origins of civilization.
