Great Pyramid vs Lahun Pyramid - Internal Structure

#greatpyramid #lahunpyramid #egyptianpyramids
The internal structure of the Great and Lahun Pyramids. A series of strong walls forming a sort of skeleton which is then infilled with rougher stone or mudbrick.

So the basic construction is buttress and fill. That makes a lot of sense when the idea is to keep a huge pile of rubble stable. Now I wonder if the known internal galleries follow the presumed alignment of those buttress structures.

Cutting corners to save time & maximise profits seems to be universal throughout the world & history .

I've always thought that the Egyptians started at the corners of Khufu's pyramid and work their way towards the center of each face and that's why you have that joint in the middle of each face of the pyramid. This method wasn't repeated for other pyramids.

Those are footers, support for weight, awesome 👍 I'm a equipment operator for a commercial landscaping company. We build a lot of retaining walls, spot on mate!

Thank you, SGD, for an interesting presentation.

consider the geometry of a trapezoidal pyramid and directional loading of it's heavy blocks in determining flexural and compressive strength. it's layered construction of running bonds mortared to a ballast creates flexural tensile strength to withstand lateral and longitudinal stresses. Continuous splines become unecessary and would conflict with an internal spiral ramp design, that is, if SCAN's findings support an internal continuous spiral ramp.

Perhaps the 'void' detected in the muon scan is in fact a fill made up of some different material such as asbestos waste fill from some nearby mine of the day. Is there a map of the Giza plateau underlying cave systems if any?

Hey, I'm a big fan and I used to believe in LAHT. That being said, I do believe civilization has been around longer than we're led to believe, that involves the pyramids and sphinx being older. What do you believe the giza pyramids are? I am open to the tomb idea although I am still skeptical. They haven't found any inscriptions or artifacts inside the main pyramid. What do you reckon ?

If they had diamond tipped blades that cut "precision" granite, why didn't they use the "machines" to cut the softer sandstone blocks?
Why did the use a "machine" then do the vast bulk of the work by hand with chisels?

_"This pyramid was made after the manner of steps which some called "rows" and others "bases": and when they had first made it thus, they raised the remaining stones with machines made of short pieces of timber, raising them first from the ground to the first stage of the steps, and when the stone got up to this it was placed upon another machine standing on the first stage, and so from this it was drawn to the second upon another machine; for as many as were the courses of the steps, so many machines there were also, or perhaps they transferred one and the same machine, made so as easily to be carried, to each stage successively, in order that they might take up the stones; for let it be told in both ways, according as it is reported. However that may be the highest parts of it were finished first, and afterwards they proceeded to finish that which came next to them, and lastly they finished the parts of it near the ground and the lowest ranges. On the pyramid it is declared in Egyptian writing how much was spent on radishes and onions and leeks for the workmen, and if I rightly remember that which the interpreter said in reading to me this inscription, a sum of one thousand six hundred talents of silver was spent;"_

Translation of Herodotus Book Two - Gutenberg Project

So while not everything Herodotus wrote is supported by the archeological record - a lot is. He as was the case back then reported history based upon oral/written accounts. In this matter his relating comports to what we see. Djoser built his Stepped Pyramid in multiple layers. The Egyptians built a large mastaba to then add layer upon layer upon layer to achieve its final steps.

So as Herodotus wrote for us it appears that Khufu similarly built a stepped pyramid initially to then fill in those steps to achieve its outer appearance. So the "niche" is likely an area where one of these devices to raise blocks once sat and consistent with time saving actions they simply covered it over rather than filling the area in neatly. They as noted encased the pyramid in white limestone working from the top down. As an aside. The 2017 muon scans showed a possible "void" above the entrance - which is further below - central to this niche. That might well be another platform area for raising blocks which also was covered over by the eventual entrance.

As to later mud brick pyramids. Quarrying stone takes time and costs money. Most Pharaohs did not actually rule for prolonged periods and Egypt was not always so prosperous. Building a mud brick cored pyramid saves time, cost, and weight. It allows for pyramids to be built in areas unsuited to heavier all stone ones as Nile mud was ubiquitous and thousands of bricks can be made daily. All that would be required is to import the casing blocks to the site as opposed to finding building sites with sufficient limestone nearby. This as Herodotus also wrote of previously to the passage above - and what we see at Giza - could be accomplished via transporting the stone via barges to ports they constructed near the site. Remember that major constructions were always co-located not far from the Nile to allow for river access.

Very interesting. Looking at the internal structure, It's no surprise really that the pyramid at Lahun didn't last.
What are your thoughts on Houdin's internal ramp theory?
