So here goes . . .
The Great Pyramid of Giza is built on an outcrop of rock.
The height of the outcrop is unknown except in two areas inside the Pyramid.
Inside the Descending Passage the start of the bedrock is approx. 64”/5.3’ above the base of the Pyramid.
The Grotto (a for the most part natural feature) up/down the Well Shaft is roughly 170”/14’ above the base.
How large an area this outcrop covers is entirely unknown, and arguably unknowable.
The Grotto appears to be an integral part of the Well Shaft, and the Well Shaft was clearly incorporated deliberately in the design of the Pyramid.
The purpose of the Well Shaft is not known.
It has been suggested that at least part of the Well Shaft running down from the Grotto predates the Pyramid.
If we assume that it does, then could it be that the location of Khufu’s pyramid on the Giza Plateau was determined by the Grotto and its original shaft?
Would this then mean that Khufu’s pyramid (G1) was the first one to be built on the Giza Plateau?
But where does this leave us with Khafre (G2) and Menkaure (G3).
To put it simply (and perhaps a tad too much so) I think that Khafre simply wanted to outdo his father’s pyramid, but without using more materials; so he had his pyramid built on a higher level of the Plateau.
Which leaves us/me with Menkaure and his pyramid.
If memory serves, the Egyptology view is that Menkaure opted for larger temples and a smaller pyramid – something to do with changes in religion and finance problems?
Here I take a step into Robert Bauval’s territory.
I suggest very, very tentatively, that Menkaure noticed that if he had his small pyramid located a bit to the left (or right, as the case made be) of Khafre’s pyramid, the layout of the three pyramids would copy the layout of Orion’s Belt, and was rather taken with it - so-much-so that he had his pyramid located accordingly.
p.s. many thanks for posting the excellent photos - they put flesh on the bones.
So few answers - and not one of them mine.
