The Orion correlation theory is a fringe theory in Egyptology attempting to explain the arrangement of the Giza pyramid complex.
It posits that there is a correlation between the location of the three largest pyramids of the Giza pyramid complex and Orion's Belt of the constellation Orion, and that this correlation was intended as such by the original builders of the Giza pyramid complex. The stars of Orion were associated with Osiris, the god of rebirth and afterlife by the ancient Egyptians.[1][2][3] Depending on the version of the idea, additional pyramids can be included to complete the picture of the Orion constellation, and the Nile river can be included to match with the Milky Way.
The idea was first published in 1989 in Discussions in Egyptology, volume 13. It was the subject of the book The Orion Mystery, in 1994,[4] as well as a BBC documentary, The Great Pyramid: Gateway to the Stars (February 1994), and appears in some New Age books.[5][6]
