Bauval found that the Pyramids/Orion's Belt correlation was general and obvious in all epochs, but specific and exact in only one: At 10,450 BC - and at that date only - we find that the pattern of the pyramids on the ground provides a perfect reflection of the pattern of the stars in the sky. I mean it's a perfect match - faultless - and it cannot be an accident because the entire arrangement correctly depicts two very unusual celestial events that occurred only at that time. First, and purely by chance, the Milky Way, as visible from Giza in 10,450 BC, exactly duplicated the meridional course of the Nile Valley; secondly, to the west of the Milky Way, the three stars of Orion's Belt were at the lowest altitude in their precessional cycle, with Al Nitak, the star represented by the Great Pyramid, crossing the meridien at 11deg 08'.8
