Robert Bauval (born 5 March 1948) is an Egyptian writer and lecturer, perhaps best known for the fringe Orion Correlation Theory regarding the Giza pyramid complex.

[1] Bauval contacted Gilbert after being interested in his foreword concerning a link between an Alexandrine school of Hermes Trismegistus and the pyramid builders of the Fourth dynasty of Egypt.

[3] He has co-authored three books with Graham Hancock, including 2004's Talisman: Sacred Cities, Secret Faith in which the two put forward what sociologist of religion David V. Barrett in a review in The Independent described as a factually incorrect and unconvincing "mess of a book" based upon indiscriminate use of source material culminating in "promulgating a version of the old Jewish-Masonic plot so beloved by ultra-right-wing conspiracy theorists.

[8] Among the idea's critics have been two astronomers: Ed Krupp of Griffith Observatory in Los Angeles, and Anthony Fairall, astronomy professor at the University of Cape Town, South Africa.

[11] On 4 November 1999, the BBC broadcast a documentary entitled Atlantis Reborn which tested the ideas of Robert Bauval and his colleague, Graham Hancock.

In regard of the nine remaining complaints, the BSC ruled against Hancock and Bauval, concluding that they had not been treated unfairly in the criticism of their theories concerning carbon-dating, the Great Sphinx of Egypt, Cambodia's Angkor temples, Japan's Yonaguni formation and the mythical land of Atlantis.
