- Osman, Ahemd
- Short review of Jesus in the House of the Pharaohs: Ahmed Osman, who is qualified in law, prefers Michael Baigent, G.A. Wells, P.L. Couchoud (a philosophy professor who wrote in the 1920s) and Sigmund Freud over historians in this book - which claims King David was Tuthmosis III, Moses was Akhenaten and finally: "All the evidence points to the identification of Tutankhamun as the historical Jesus" [164] (while also stating all four gospels agree Jesus was crucified when Pilate was governor [17]) Hence this short review.
