excerpt from Andrew Collins - Beneath the Pyramids
One clue regarding Gebel Gibli's role at Giza is the Dream Stela, an inscribed stone slab set up between the paws of the Sphinx. It was erected by the pharaoh Thutmosis IV to commemorate the role played in his ascension to the throne by Harmachis (Hor-em-akhet, Horus in the Horizon), an ancient name for the monument. It refers to the Sphinx being located "beside Sokar in Rostau", with Rostau being the ancient name for Giza. Significantly, Rostau means something like "mouth of the passages".
Sokar is arguably one of the oldest gods of ancient Egypt. He presided over death, resurrection, as well as the darkness of the tomb in which the dead lay in eternal slumber. Sokar is usually shown as a falcon-headed deity, either seated on a throne or wrapped as a mummy. He was guardian of the Memphite necropolis, in particular its northern extent of Rostau. Here was to be found a shrine to Sokar called the Shetayet, quite literally the "tomb of god" (a variation of the same name is used to describe the vulva and womb of the sky goddess Nuit). Although its location has never been determined, some have considered it to be in the vicinity of Gebel Gibli, beneath which lies the well Bir es-Samman. More revealingly, Sokar has been identified with the mythical leader of the Edfu texts known as the Falcon, whose mythical precursors, the Primeval Ones, were responsible for building Egypt's first temple and enclosure, on the banks of the lake containing the sacred island of creation.
Sokar's great rival, even by the Pyramid Age, was Osiris, the god of death and resurrection. His cult absorbed the falcon god's attributes and sites, until Sokar became simply Sokar-Osiris or even Ptah-Sokar-Osiris, after Ptah, the creator god of Memphis, whose cult also absorbed that of Sokar. Even though Osiris most probably started as a vegetation god of the Nile Delta, associated with cycles of regeneration, he quickly usurped Sokar's role as "Lord of Rostau". Even the Shetayet, the lost womb-like shrine of Sokar, evolved into the "Tomb of Osiris".
Yet one place that Sokar continued to rule was the Duat, the Egyptian underworld, or Netherworld, seen as both a physical realm beneath the earth, and also as a region of the night sky associated with the Egyptian afterlife. The Am-duat, or "Book of that which is in the Underworld", a funerary text used during Egypt's New Kingdom period, c. 1575-1214 BC, speaks of Sokar as governing the subterranean realm of Rostau, the name given to the Fourth and Fifth Hours of the Duat. The deceased pharaoh in his role as the sun-god would have to navigate through the Duat in order to reach an afterlife among the stars. The ancient Egyptians believed that the trials and tribulations that the soul of the dead pharaoh would have to undergo on his dark journey through the underworld were reflected in the sun's journey through the hours of darkness.

T Bird : Here it is.....evidence of a different named God/Creator group and building.
Edfu ...... the Winged Disc emblem.....suggestive of the Shemsu Hor and those who go back in time to the Demi God period .
Osiris replaces Anubis....
Osiris is the Pole Star Canopus which went away from being the Southern Pole Star [Osiris cut up into pieces]...end of the Pole Star.
Vega/Canopus in a far earlier age is tagged with global calamity...the fall of the Pole Star Vega/Ice Age....fall of Atlantis?
I think we do find the Egyptians forwarding the change of Zodiac ages here,change of Pole Stars.
Excerpt from Carl Muncks website:
The Bent Pyramid of Seneferu (??) The Bent Pyramid, at Dahshur, Egypt.
Why was this pyramid really "bent"?
Could it really have been built by Pharoah Seneferu?
Must its builders have had advanced global positioning technologies?
That's what it's called, this rhomboidal pyramid at Dahshur, Egypt. History asserts that due to a fear of collapse on the part of its architects, the upper body of this structure was built less steep than the lower.
Sorry, but the Bent Pyramid was bent before it left the drawing board.
To explain to ANYONE just WHY it is exactly WHERE it is!
The language used to explain it is entirely numerical, that involving latitudes and longitudes. Here’s how it works...
(1) Upon observing it, think about its presentation. What does it SHOW?
a.The upper body ("bent”) conveys four 180° triangles, for a grand total of (180° x 4 =) 720 degrees.
b. Each side of the lower body has 360 degrees of corner angles (x 4 sides = ) 1,440 degrees. The WHOLE pyramid then shows 2,160 degrees.
c. As with any other pyramid, this one has four base corners, but unlike a true pyramid which has four sides, this one shows EIGHT.
d. Multiplying these DEMONSTRATED numbers (2160° x 12 = 25,920)
e. This product ENCODES its latitude thusly:
25,920 : 29° : 47' = 19.0168745414" North Latitude
(2) Skeptical? You want a second opinion? No problem… Latitude:
a. Again, the upper body emphasizes the 180-degree triangle - 180°
b. There are NINE extremities on the Bent Pyramid; four corners on the ground, four more corners mid-way up, and, of course, its apex. 4 plus 4 plus l - 9
c. Then its eight sides - 8
d. Finally, its distinctly different upper & lower bodies - 2
Did we miss anything? Nope. We have it all… So...
180° x 9 x 8 x 2 = 25,920 (: 29° : 47' = 19.0168745414")
The Bent Pyramid SHOWS us why it is where it is. It was therefore “bent" before its cornerstones were laid!
Egyptology says the Bent pyramid was a failed undertaking and revised.
This is entirely wrong considering the information....considering that Pyramid shouts out loud 1 Precessional age in years 
and yes....more evidence these Ancient Pyramids are vastly older than Dynastic Egypt....who adopted them.
The Template concerning Sokar does speak of an far distant earlier Age and building.
