The Documented Ancient Construction Method of The Great Pyramid

My name is Paul Hai and my book deals with ancient text documentation which tells us how the Pyramids of Giza were constructed. The first document is found in the first chapter of the Book of Ezekiel in the Old Testament of the Holy Bible, written by Priest Ezekiel c.590 BC. The second document is written by Herodotus, a Greek historian widely regarded as being “the father of history”. Herodotus asked many questions in his travels and recorded what he was told. In c.450 BC the Giza priesthood personally told Herodotus what they knew of Giza Pyramid construction.

This book deals with ancient knowledge and wholly refutes all modern Giza Pyramid construction theories as nonsense and/or not feasible. Those who have read “Raising Stone 1” have a head start in understanding the documented source information and others will need some patience in understanding the explanations and verification of ancient Egyptian Pyramid engineering techniques.

The ancient documents mentioned are critical for proof and primary source documentation; when and where it exists is demanded for university level research studies. Unfortunately many university professors have concluded that the Herodotus documentation is false regarding wooden machinery being used to construct the Great Pyramid, and this has led to a steady flow of people intent on putting forward their own ideas resulting in a free for all of mostly complete and utter nonsense.

After I established the Herodotus documentation to be truthful, I then turned my attention to the machines mentioned in the Old Testament of the Holy Bible in Chapter 1 of the Book of Ezekiel only to find the writing difficult to comprehend, but have found common ground throughout the twenty eight verses.

The descriptions in Ezekiel confirm the use of excavated wooden wheel lobes known to many as “Petrie rockers”. Anyone who is serious about understanding Giza Pyramid construction techniques should limit themselves to three sources of study:

Ezekiel Chapter 1,
Herodotus – The Histories – Book 2 – Egypt and
my book “Raising Stone 1”, which is an engineering dialogue; or at least use my website, as a study guide.

Ezekiel appears to write metaphorical nonsense and this may have been intentional as knowledge was, and still is, powerful. Reading studies begin with Ezekiel Chapter 1, verse by verse unless some verses are repetitive.   If my reader decides to opt for modern theories promoting ramps and kites and such, of which there are many, all totally unstructured toward a critical result, then you will be lost. Lots of hot air out there and talk is cheap; so begin studying for what you wish to understand and listen carefully to what the ancient people have documented through their scribes. The answers are there, but patience, alertness, critical thinking and fortitude are required.

Paul Hai’s book  “Raising Stone 1: Paul Hai’s Racks and Pinions Theory” documents this construction technique and openly challenges the conventional wisdom of the traditionally accepted explanations of the method used to move 2,500 kg blocks in the construction of the great pyramids.

    Here’s a clear, down to earth, Occam like explanation for the construction mystery of the great pyramids. We need more of these confidence building engineering solutions for laymen. Too often we drift off into speculation that can’t proved or disproved. It’s a good feeling to have one’s feet planted firmly on the ground. Then we can springboard as high as we want.

    I said before that I think Paul’s nailed it. I still do. Especially given the tensile strengths in question.

    Congratulations Paul for your book !
    I hope that many people will read it, a story of ancient engineering,
    long forgotten but never researched in this way as Paul did it !

    Paul, Good to see your work published by a trusted news site. The construction method you present regarding the Great Pyramid at Giza seems to be the only one backed by analyzing the accepted records. I imagine that many other “mysteries” can be solved this way. The “Ramp Theories” never held up in my practical mind. That pyramid in particular seems to be some sort of energy focusing/producing “machine”. Those interior structures and chambers and shafts just don’t say “tomb” to me. Your deciphering of the written records and model artifacts found in tombs of the area are the basis for a solid proposition. Rack and Pinion!

    Mechanical tradesman Paul Hai, inspired by the reports of the Greek scholar Herodotus from his visit to Giza, Egypt around 450 BC, has come up with an explanation of how the Pyramids were built (see his letter published in our last edition).

    Taking the historian’s cue that the Giza Pyramids were “built in steps, battlement-wise” and that after laying the stones for the base the constructors “raised the remaining stones to their places by means of machines formed of short wooden planks”, Hai had a brainwave that a pinion-pulley system with wooden “rockers” was utilised. He suggests that cross-pegged wooden “lobes” were fitted radially around each block of stone, weighing an average of 2,500 kg with approximate dimensions of one cubic metre, with four quadrants forming the pulley drum. A hoisting rope was tied to one of the pegs and wrapped around the drum until it was fully loaded with rope. The free end of the rope was then attached to a shaduf, an ancient type of crane, a class-one lever. Three ropes were probably wound to share the load. The load lay inside the pulley and the entire pulley wheel – a class two lever – could then be hoisted higher using ropes guided by a grooved bearing stone. The pulley utilised the initially placed stones as a rack, helped with the placement of wooden rails. A claw-lift crane was then used to position each stone in its place, the claw fitting into pre-gouged holes in an already-placed stone. Hai says such an apparatus could provide a 2.8 mechanical advantage, thus a 2,500 kg load could be hoisted with three ropes, each sharing 300 kg of load.

    Hai points to excavated artifacts which confirm that the Pyramid-builders used these technologies and that this construction system would have been much more efficient than one using a ramp. His self-published book Raising Stone contains many colour illustrations and photographs to show how this ingenious construction method could have worked. It seems he’s onto something.

    MOUNT Isa can claim an outstanding achievement on the world stage by a citizen, Paul Hai, whose racks & pinions pyramid construction theory presented in his book Raising Stone I, now on sale at Mount Isa book outlets.

    Although it must yet withstand world wide challenges to gain official recognition, it advances published thinking on those ancient construction achievements dramatically beyond the point reached by the past collective efforts of all Egyptology explorers and researchers, strongly indicating that win, lose or draw in the academic stakes, the Paul Hai theory will ensure that old Egypt can never again be considered in the same condescending way following what must have been their industrial revolution.

    Paul Hai has never visited Egypt, but when required to write an essay on pyramid construction for his university history course, he opted to reread the largely ignored c. 450 BCE Giza records by Herodotus of Halicarnassus, rather than to follow the “sand ramps” theory trail fostered by university libraries, requiring massive sand ramps to deliver and elevate stone blocks to pyramid sites.

    The resulting new construction theory is presented in an easily read and understood book that will have any age group reader fully informed by both the well written text and diagrammatic colour plates clearly depicting each progressive block handling step at Giza.

    Few will doubt Paul’s racks & pinions construction theory, because the evidence shows that civilisations predating the Egyptian Fourth Dynasty period used well known and understood simple mechanical lifting devices (eg shaduf/crane) that would surely have been used to draw irrigation water from the Nile, renders the possibility that Egyptian engineering knowledge and practice suddenly took a backwards step by building massive sand ramps rather than evolving their existing technology, is ludicrous.

    The clues that prompted innovative thought resulting in the new recognition may have been – must we accept the modern line that ancient Egypt, with its massive stone temples, monuments, public works etc came without the evolving benefits of mechanical advantage apparatus, simply because engineering thought played little or no part in telling the story of Egypt’s greatest buildings? Something that wouldn’t rest easily with Mr Hai’s mechanical background.

    Paul’s new theory will, correctly, undergo academic scrutiny sure to question, as will any reader, for example, whether cedar timber could withstand the rigours of pulley quadrant life.

    But the type of timber is immaterial and a people able to import Lebanese Cedar, or indeed Ethiopian fancy pyramid building stone, could manifestly source any fence post length, tough timber of choice.

    However, if the professors do consign it to oblivion, it will be simply to preserve well established calf-trails.

    Paul Hai shows that mechanical, construction and tool principles employed in those ancient works are clear forerunners to the evolved technologies and modern advanced tools that in many cases must reflect original conceptional recognition and credit to those ancient Egyptian technologists.

    Raising Stone I is essential reading for everyone – families, schools, the trades and universities.

    PAUL Hai is “99.9 per cent sure” as to how Egypt’s Great Pyramids were built. So assured is this first-year history student that he has spent tens of thousands of dollars to become an author, illustrator, publisher and distributor. Although he believes it will “cause a lot of debate and is going to rock the boat a bit”, the first 10,000 copies are planned for primary schools, high schools and university book outlets.

    The secret of the Pyramids, according to Hai, is a rudimentary pinion-pulley system operating on the same basic principle as a three-wheeled step trolley or a motor car’s rack and pinion steering. In Hai’s theory, the rack is the Pyramid itself and the layers of stone behave like teeth. There were many “pinions” that engaged the Pyramids “teeth” and revolved towards their apex. These were the 2.3 million 2.5 tonne stone blocks that made up the Pyramids themselves.

    Each block was skillfully fitted with a wooden lobed scaffold, almost like petals surrounding a flower. It was in the cavities between the wooden lobes that these makeshift pinions engaged the Pyramid’s stone layers. The pulley effect occurred through a series of Lebanese cedar “A-frame” levers.

    Taking his inspiration from Herodotus, Hai pushes his calculations even further and reckons that with 40 pulleys and 40 cranes working each day, the Pyramids would have taken 20 years to build.

    Apart from some obvious publication constraints, Hai’s simple instructive writing style holds firm. Among the formidable research, mathematics and engineering data, Hai submits a lucid and broadly engaging argument to a topic that has tormented scholars for more than 4500 years.

    I just finished to read the book of Paul ” Raising Stones 1″ . A very interesting reading, with a lot of technical details, well written and illustrated, easy to understand even for a novice in technical issues as I am. I cannot comment on biblical questions and interpretations such as Ezekiel, I better leave it to those who understand the Old Testament. But in all, Paul has written a book based on logic and critical thinking, which I really appreciate, offering a lesson of ancient technological history from a different perspective, unbiased by religious or/and political views. I am convinced, that this book will open the minds of many people and in the same way, will give an opportunity to ample discussions among those in knowledge of ancient construction methods, rediscovering maybe the lost or hidden vestiges of that past know-how in human history. Thank you Paul !
