Graham Phillips is a British author. Phillips has a background working as a reporter for BBC radio, and he was the Founding Editor (1979) of Strange Phenomena magazine. He has made a number of controversial claims concerning the Arthurian legend, such as the discovery of the 'Hawkstone Grail', a small stone cup that he claims is the original Holy Grail; the identification of a Roman ruin as the "historical Camelot"; and the claim to have discovered King Arthur's grave. He has also investigated various biblical mysteries, again presenting some controversial theories, such as an alternative location for Mount Sinai at Petra in Jordan, an Egyptian staff in a British museum as the staff of Moses, and a grave on the British island of Anglesey as the tomb of the Virgin Mary.
