Hi Graham,
Thanks for your help.
It seems clear to me, having looked at fig 5 for the first time just a few minutes ago, that the level of 0.75 metres is clearly labelled as the base level of the inner structure which therefore had a base level 10 palms higher than the bent pyramid base level.
The bent pyramid base level is clearly labelled at 0.0 metres relative to the inner structure, and it is also clear that the inner structure does not exist anywhere near the edges of the Bent Pyramid.
Therefore Dorner and Petrie measured the same side length of the Bent Pyramid, that's why their survey measurements agree so precisely.
There is nothing in the corners of the Bent Pyramid that is 0.75 metres higher other than a projection from the inner structure which appears to be meaningless, but perhaps Dorner is pointing out that his scheme of 362 cubits (from a shorter cubit than Petrie's cubit) is not irregular in that there is a conspicuous reduction from 362 cubits to 360 cubits from such a projection.
If it were true that the inner structure is 0.75 metres higher than the outer structure then Dorner's odd length of 362 cubits would appear to be reconciled in a satisfactory manner which is I believe the case Dorner is making, but my drawing of the cross-section, published on my website 10 years ago, showed that an inner structure would be expected to have a length of exactly 300 cubits if the outer structure had a length of 360 cubits with with the inner structure and outer structure having the same base level.
If my geometric analysis is correct then base of the the inner structure is not 75 cm higher than the base of the Bent Pyramid.
Dorner shows the level to the Bend as 90 cubits from the base level of the Bent Pyramid not from the base level of the inner structure. This, I think, is telling us that the bend is at 90 cubits above a pyramid with a side length of 360 cubits.
Would it not be extremely difficult to determine the level of the base of the inner structure 30 cubits inside the base edge of the outer structure?
My geometric grid of the cross-section has a number of remarkable features. I was surprised that the diagonals of the grid intersected the base of the Bent Pyramid at a separation of exactly 300 cubits which was not something I set out to achieve. It is obvious from my drawing that other features appear to govern the plan. ie it would have been natural to draw the diagonals if that was the plan and then to see the intersection.
Dorner shows us quite clearly what he measured in metres which was the real length not a supposed length above the real length.
The 75 cm level appears more like a hypothetical design difference as it is so incredibly close to 10 palms as the required difference to correct from 362 cubits to 360 cubits from the tangent 10/7 with 7 palms per cubit.
Mark
PS
I hope to see a diagram of the Red Pyramid, or at least more details of Dorner's survey where I can actually see or read what he proposed with regard to the side length and slope. I think I have a simple plan that explains all in line with my model of the Bent Pyramid.
