Robert Bauval, auteur du Mystère d'Orion et du Code mystérieux des pyramides, est, entre autres, au cœur des débats, sa théorie étant, très sommairement, que les Égyptiens bâtirent leurs pyramides de telle sorte que leur implantation soit l'exact reflet d'une carte du ciel englobant la constellation d'Orion.

"The Pyramid Texts embody the remnants of a well-structured star-cult, the main theme of which was the transfiguration of the dead pharaohs into stars. Examination of the Pyramid Texts reveals that the dominant stars of this cult were those of the constellation of Orion. The special attention given to Orion can be understood in several ways: it is the most striking of the constellations ; in the archaic Period, it happened to rise in midsummer at dawn (c.2600 BC ) , as though a celestial herald of the forthcoming yearly nilotic flood. Consequently, the appearance of Orion after a prolongued period of 'invisibility' was taken as the celestial event preluding a new season of rejuvenation and growth of nature as a whole. Mythologically, Orion was thus seen as the celestial representation of Osiris, the god of rebirth/resurrection, and with whom all the dead pharaohs, as star-gods, were identified. Thus the Pyramid Texts proclaim : 'Behold, he has come as Orion, behold Osiris has come as Orion... O king, the sky conceives you with Orion, the dawn-light bears you with Orion, you will regularly ascend with Orion from the eastern region of the sky, you will regularly descend with Orion into the western region of the sky...' (pyr.820-822). 'O king, you are this great star, the companion of Orion, who traverses the sky with Orion, who navigates the Netherworld with Osiris, you ascend from the east of the sky, being renewed in your due season, and rejuvenated in your due time.' (pyr.882). 'Live, be alive ! Be young beside your father, beside Orion in the sky...' (pyr. 2180)."
