Is There More to the Mechanics of the Great Pyramid?

Getting your Trinity Audio player ready...

At the beginning of March, Egypt’s Ministry of Tourism & Antiquities (MOTA) announced a newly discovered chamber above the main (North) entrance to the Pyramid of Khufu, also known as the Great Pyramid of Giza, outside Cairo. This 9 meter by 2 meter chamber sits directly above the North entrance, and why it was included there currently remains unknown. Could it be part of a long since dismantled locking system?

Another cavity exists between the Grand Gallery and the King’s Chamber, and far more is known about this space, which has a 3 stone blocking mechanism. But it is still somewhat enigmatic. Here, with an analysis of what is known of the construction of the blocking mechanism of this Antechamber, a mystery of the whole of the pyramid’s design is explored.

Current Thinking on the Antechamber to the King’s Chamber

From the time of the early archaeologists, the Antechamber between the Grand Gallery and the King’s chamber of the Pyramid of Khufu has been supposed to be a blocking device with three granite blocks in a row. The empty sarcophagus in the King’s chamber, the majestic Grand Gallery leading to it and this elaborate closing device led everyone to accept blindly that this was Khufu’s burial chamber. Three blocks were obviously meant to seal this chamber off.

This remains the accepted interpretation of the Antechamber. However, it is the author’s opinion that several details in the Antechamber call for a better explanation. He thinks this falls into the trap of providing a superficial explanation. With this explanation, the antechamber has a one-time-use function.

But further analysis of the features of the chamber hints this might not be the case. Instead of for one-time use, the Antechamber could be a marvelous construction meant to be used again and again. It could be an opening and closing device, not just closing.

This article offers an alternative view on its purpose and function. One that incorporates conveniently neglected details like the four vertical grooves on the southern wall, small alterations of the floor level, and more. A view suggesting that the King’s chamber wasn’t his burial chamber, but had a different function.

Challenging Some Assumptions

The archaeologists focused solely on finding the burial chamber, taking the sarcophagus in the King’s chamber as proof. Not least because the two chambers lower in the pyramid appeared unfinished, it was easy for them to conclude that these two chambers were abandoned during the building process. One chamber wasn’t dug out properly, they thought, and the second was missing a half a meter thick layer of floor tiles.

They were so wrong.

Let us do some architectural detective’s work and begin with a critical view on the three-stone-block idea.

The blocking is assumed to have worked this way. Maragioglio & Rinaldi: L’archittura delle piramidi Menfiti, parte 4, tavole (tav. 8 detail).

The vertical protruding “ribs” on the east and west walls looks like guiding lines for blocks. Fair enough. But why three, when one bigger one would be sufficient? Is it symbolic?

This way of blocking the entrance is not used in other pyramids we know of. Cylindrical rollers over the blocks seem to have been used to lower them into sealing-off position. Accurately measured drawings of Maragioglio & Rinaldi show how the blocks, in their view, were simply held up temporarily by wooden logs. So, while others bashed the supporting logs away, the blocks were held back by workers holding ropes, and then slowly lowered into their closing position.

I have calculated the weight of one such stone block to be approximately 1.5 -2 tons, (1.2m x 1.2m x 0.5 m = approx.0.8 m 3 x 2.5 t (average weight of 1 m 3 granite) = approx. 2 t). So it would have taken the weight of 20-30 Egyptians weighing 70 kg each just to hold one block. They must have been standing in the Grand Gallery. But why have nice rollers above the blocks and then a sharp – not even rounded - edge on the corridor’s ceiling. It doesn’t seem well planned.

And what about the open shaft in front of the closing blocks? If the blocks were supposed to be lowered by gradually slacking the ropes over the cylindrical rollers, it leaves this “pre-Antechamber” open to intruders afterwards, who would quickly realize that only the inner of the three blocks would have to be broken to gain access to the supposed burial chamber. Not very smart, though I admit that the damage to the southern wall (repaired) could suggest an attack from above.

But why use rollers at all?

This was a very complicated system for a one-time use. Ropes would easily slide over rounded edges of normally square blocks - the friction would even help the careful lowering, giving an argument against the roller idea - and with just narrow gaps or holes in the masonry, grave-robbers would have had a much harder job.

The rollers led me to conclude that they may have been familiar with pulley systems. Also, because I believe in Australian Paul Hai’s theory: that they rolled big stone blocks, even up the pyramid sides, with the help of convex wooden “sleighs” fastened to the blocks. Models of such sleighs or “rockers” are found.

Gods and Chambers

In an earlier article I have proposed that the closing system was designed to be used time after time and was made as a counterweight opening and closing system. It is the most logical reason for using rollers to eliminate friction.

The idea suits my basic theory that all the chambers in the pyramid were equally important.

I believe that each chamber honored one of the cosmological gods of the area. The Giza pyramids are only 30 km from Heliopolis. The five first listed gods there were gods for nature elements – earth, water (actually rain and mist = water moving vertically), and air, for some, and the three chambers we know were formed to suit one god’s element each. The gods in question were Geb, Tefnut and Shu respectfully.

And yes, I do believe that two other chambers existed: one on top of the pyramid honoring the sky goddess Nut, just covered by the pyramid’s casing stones until they fell off in an earthquake, which also loosened many of the casing stones from the sides; and a hidden chamber honoring the sun- and creator god Re-Atum. These five were the gods who had created the world.

Built vertically into the pyramid the chambers were steps on a ladder helping the deceased king ascend to heaven.

All the Chambers Display Symbolism

I believe that Khufu was buried in the subterranean chamber. The chamber was not unfinished and abandoned. This was the earth god Geb’s chamber, and a lot of the bedrock was left, intentionally giving the impression of a quarry. We can imagine how stone masonry was highly respected in ancient Egypt – a divine craft associated with Geb, I presume. Looking carefully you will see that there is a flat level area big enough to house a sarcophagus, wooden, assembled on the spot.

When the Greek historian Herodotus visited Egypt two thousand years after Khufu lived, priests told Herodotus that the king lay buried under the pyramid, on an island surrounded by water coming from an artificial canal.

Now watch how much difference a little imagination can result in: All it takes to make us realize that Herodotus’ words may be a rather precise description of an incredible original tableau is a square wooden tube. Placed vertically in the well, with two sides resting on the cut-out ledge and tightened with clay or silt you would have a proper water well (it has been dug out deep enough to conclude that it reached ground water level at least in flooded periods).

Why have they dug the well so deep? Because they needed a lot of water. Pouring water onto the floor would result in a tableau like the one I have drawn. And more water was needed higher in the pyramid.

The Queen’s chamber and the Grand Gallery were wonderful gems too and call for attention, but they are only briefly referred to in this article. The Queen’s chamber had water on the floor and water in the closed canals.

Details reveal that the Grand Gallery is not my missing chamber for the sun god – the sloping Gallery is clearly not a chamber – and anyway his chamber should be closer to the sky/the top chamber. I have come to the conclusion that the Gallery is linked to the sun anyway, in the respect that it represents the sun’s rays, bringing warmth, light, heat, fire and life to the lower world. It represents the fire element on earth, whereas the sun god’s actual chamber is higher up.

Counterweight System Details

After a critical examination of the system I previously proposed for the opening and closing system: a wooden tube, balanced by a stone block in the first shaft, I have realized it was a hasty thought. A wooden tube, even three times the size of one blocking stone, would not balance the weight of a heavy stone counterweight. A wooden tube, even 20 cm (8 inches) thick and having a base area of approx. 1x2 meters – 2 square meters, would only weigh as much as 600 kg, having the average weight of e.g. cedar wood.

The remains of the counterweight stone from the shaft in front may very well be the broken stone block with drilled holes on display outside the pyramid’s entrance. From the looks of it (I haven’t measured) it is as thick as the other assumed stone blocks, therefore possibly weighing 1.5-2 tons.

I regret having to give up the wooden tube idea. The side walls’ ribs of stone would function as fine guides preventing the tube from getting stuck (from tilting forwards or backwards). I do realize that a tube could be made heavier by putting extra stones on top of it or inside the tube, but a whole extra ton?

Another counterweight possibility: a stone basin, closed and open. The grill (see below) still waits for someone to pull the rope. (Author provided)

A Low Stone Basin

To balance a stone block, “the wooden tube” must instead have been made of stone. A basin almost formed as a sarcophagus, open in both ends, would work. With side wall thicknesses like the sarcophagus inside the chamber, which is c. 15 cm (6 inches), the side walls of a stone basin may have had about the height of the corridor, and contained some water.

Alternately the basin could have had rather low sides and a bottom thickness of about the half of the counterweight, c. 25 cm (because the vertical counterweight area is roughly half that of the floor area under the three rollers). The low side version is shown here, but higher sides would better prevent it from being stuck by tilting.

Grooves for ropes or a grill?

The interesting vertical grooves on the south wall, over the last bit of corridor leading to the King’s Chamber, could have given room for the ropes holding the inner block, in the popular three-block version. But why, in that case, were the grooves chiseled in all the way up to the ceiling? Even though the big wall stone with the most of the grooves ends a little below the ceiling, the grooves continue on another stone. That would not be necessary, if those grooves were for ropes around the roller.

The grooves could instead have guided a grill, blocking the entrance. It could be lifted with a rope going around the closest roller. It is the best use I can see for these grooves. The grill can be held close to the wall with a wooden beam or two, crossing from wall to wall. An explanation to why it should be there is proposed below.

Temple Functions

Rites were carried out in the grave temple outside the pyramid. Could the pyramid itself be a temple? The later roman writer Apuleius describes in his book The Golden Ass his own initiation into the Isis cult. He wrote that he came to the boundaries of death and then returned, going through all the elements. The Greeks had (re-) invented the elements by then, without gods, but his significant words about elements give meaning to speculations of whether Khufu’s pyramid with its element chambers functioned as an initiation temple as well as grave for a king.

In such a context the Ante-chamber’s layout is very interesting. Coming to this level the initiate would have descended to the bottom chamber, had seen the sarcophagus, had noticed the bedrock linking this chamber to the earth god Geb, had noticed the water seemingly floating in from the square canal on the opposite wall, and seen the hollow upper end of the wooden tube, seemingly a hole to the underworld. To him, this was the boundaries of death.

From here he went up, visited the Queen’s chamber (Tefnut’s watery element), and had passed through the stylized sun beams of the Grand Gallery. Now he stood on the landing in front of the last earthbound element’s chamber, the air god Shu’s chamber. He was the god who had lifted the sky from the earth and was still holding it up by his hands, standing on the earth.
The initiate found the entrance closed.

A Test

Standing in front of a closed entrance must have felt like being tested. Now what? He should probably demonstrate that he mastered manipulation of the elements he had passed on his way.

One of the earth element’s most obvious powers is its weight. Could he overcome that?

The blocking stone didn’t rest perfectly on the floor. A one-centimeter gap gave him no other choice than to try to lift the stone by hands, if he wanted to enter Shu’s chamber. So he tried - and the block moved (due to the low-friction rollers)!

The next thing he saw was glowing and burning charcoal (or dried camel dung) in the next three to four meters (the floor is depressed here, and the air channels in the chamber conveniently ventilated out most of the smoke). Fire… how could he pass this fire without getting grave skin burns? Furthermore, a grill blocked his way, and a much larger stone block was coming down as he lifted the entrance door.

Lifting the door stone all the way up revealed that the descending stone was a stone basin, covering the first half of the burning path. The basin contained water.

Having stood in water in Tefnut’s chamber he would now rely on her help to extinguish (control) the fire in a narrow path. Having wet feet would also help him to a safe passage.

Just the grill remained. Either it had gone up automatically when he lowered the basin, or better, a dangling rope gave him the final opportunity to demonstrate decision and will to enter Shu’s chamber.

In line with later initiation symbolism the sarcophagus in Shu’s chamber implies that the initiate now had to symbolically die by entering the sarcophagus and well, maybe die “the small dead”- go to sleep, or in another way open his mind to the afterlife : he was spoken to by heavenly voices, coming from somewhere (above the ceiling)! This was probably the reason for the narrow-dug tunnel leading from high over the Gallery landing into the lowest of the so-called weight-relieving chambers above the King’s chamber.

This finished his task – now he was reborn, having been dead, having been spoken to by gods.
Having realized that the elements and their chambers were steps in the pyramid’s stairway to heaven - he was now initiated.

And we are too, having understood and refurnished the Antechamber.

Herodutus is mentioned in the article, and some accounts refer to Herodutus’ ‘lies’, but he just reported, literally, and in the true sense of reporting (and not opinion or speculation) what the locals told him. These could be legends or beliefs passed down over generations, in the same sense that some cultures report their beliefs about the creation of the world, gods that walked the world and will return, and so on. Today, gatherers of the legends of more primitive and advanced cultures do the same. He also reported by direct observation.

In the case of pyramid building, he was told by priests that small cranes were used to raise blocks level by level, simply by moving the mini-cranes up as the height increased. He was also told by them that waterworks were below the pyramid, but these could be memories passed down that water was indeed in the proximity of the pyramid, and recent findings are that the Nile did approach the Giza plateau. This would certainly help in the transport of materials by boat.

The article refers to portcullises not being found in other pyramids; the second pyramid (Khafre’s) has two of them in the descending passage. Perring and Belzoni both encountered them; Belzoni reported that one was raised about 8 inches above the floor. They are actually quite common in ancient structures, again, a simple and obvious approach to prevent, hinder, and delay invasive progress.

Rather than complicate before we simplify, when assessing these ancient monuments it may be best to consider the obvious. When considering, for example, the shape of pyramids, the obvious realization is probably that to achieve the greatest height of a monument (as we still wish to do today for political or propaganda reasons, or just simply to impress the observer), in ancient times before technology and materials allowed it, the method to just achieve great height would be to make each successive layer of construction smaller than the next lower one. Even in corbelled vaulting of chambers, to achieve great height in open space, this was the method used to achieve strength and stability –  in Khafre’s and many older pyramids corbelled vaulting was used.

This article is somewhat refreshing in that it does both push back ‘a little’ on the absurdity of the existing theories while attempting to apply logic to the functionality of the great, ancient structure.  First, let’s be clear that any ‘logic’ used today to understand the intents of the ancient people is THE SAME LOGIC that they would have used.  Logic does not change.  One plus one equals two, just as two equals one plus one, and that is true both now and then, and eternally.  So, we’re starting off on the right foot!  

But the problem is, there is so much illogical non-sense associated with the ancient structures, many of which lie overtop of dead bodies, and here the entire region was once a ‘ground zero’ for mass death and subsequent cultural demise, almost certainly associated with the Atlantis event (circa 115k BC, adding the zero back to Plato’s timeline – a big side issue there for another day).  So there was/still is an attempt to divert from that ancient calamity (a truth too dark for many to handle), and they do it by having us believe the absurd – that these impressive structures, which certainly took ancient society THOUSANDS of years of progressive evolution to conceive, design and construct, were for the purpose of burials and after-life considerations.  But does the logical mind of today, which is the same as the logical mind of back then, believe that?  Doesn't that more fit the category of NON-SENSE?  And also doesn’t that more fit the category of DECEPTION?  Also noting that the ‘father of history’ Herodotus, was/is also known as the ‘father of lies’, so be cautious with him, as history and lies are an eternally devilish marriage.

But back to the structure and its true purpose.   There are many ancient pyramids on nearly all continents.  Three things are common to them:  One, they are massive; two, they oriented by the cardinal directions, and three, there are fresh water aquifers at their base (if you look).  Logic should thus tell us that they have something to do with WATER, not dead bodies!  By the way, the ancient Greek root word in funeral is torch, which was their ceremonial (and logical) way of disposing of dead bodies, which would never come anywhere close to the source of their drinking water.  So the theory should be, or fact is – it's almost too easy – that they were built as gravitation water pumps, with the mass and the orientation designed to geo-magnetically pull water UP from below.  This follows the science of geo-hydraulics (investigate it if you don't believe).  So once the water is made to rise, LOGIC tells us that the ancient people wanted to use it, and thus would have designed channels, and stops (essentially big crude ‘gate valves’) to have the water go where they wanted it to go, and not where they did not want it to go.  Look at the Bosnian Pyramid, of same basic design, except in a more primitive way, where rough stone (not cut blocks) was used for opening and closing the many subterranean channels under and around it.  

Everybody understands how important fresh drinking water is.  Only such an important thing like that would LOGICALLY have an ancient society doing all the work to assure a continual supply of pure, clean, mineral-rich water from the deep aquifers.  There would NOTHING more valuable to an ancient society.  We can also look at how the ancients engineered their Qanat systems, which were similar to the function of pyramids:  And of course, there are also the ancient aqueducts, designed/constructed carry water from the best aquifers OVER RIVERS via huge stone arches.  The ancients were very particular about their water sources!

Nobody gets paid to tell the truth.
