Lost Technologies of Ancient Egypt

From the pyramids in the north to the temples in the south, ancient artisans left their marks all over Egypt, unique marks that reveal craftsmanship we would be hard pressed to duplicate today. Drawing together the results of more than 30 years of research and nine field study journeys to Egypt, Christopher Dunn presents a stunning stone-by-stone analysis of key Egyptian monuments, including the statue of Ramses II at Luxor and the fallen crowns that lay at its feet. His modern-day engineering expertise provides a unique view into the sophisticated technology used to create these famous monuments in prehistoric times.

Using digital photography, computer-aided design software, and metrology instruments, Dunn exposes the extreme precision of these monuments and the type of advanced manufacturing expertise necessary to produce them. His computer analysis of the many statues of Ramses II reveals that the left and right sides of the faces are precise mirror images of each other, and his examination of the mysterious underground tunnels of the Serapeum illuminates the finest examples of precision engineering on the planet. Providing never-before-seen evidence in the form of more than 280 photographs, Dunn's research shows that while absent from the archaeological record, highly refined tools, techniques, and even megamachines must have been used in ancient Egypt.

CHRISTOPHER DUNN is a manufacturing engineer with 50 years of experience. He has worked primarily in aerospace with an emphasis on precision and laser application. He has published a dozen articles on his theories about ancient technology and is the author of The Giza Power Plant. He lives in Illinois.

“Christopher Dunn is an expert in his field. He knows a great deal about stone-cutting tools and has spent many years studying the ancient Egyptian monuments, sculptures, and artifacts. His findings are revolutionary. His word carries weight. If he is right, our perception of who the ancient Egyptians were may completely change. Read this book!”


“Christopher Dunn’s painstaking work, literally, makes the ‘stones’ of the Egyptian gods speak. He provides profound archaeological evidence that shows an engineering consistency, suggesting an advanced intelligence, which understood the supreme science of sacred geometry. A must-read book for those who wish to understand the advancement of Egyptology in the world of today.”


“Utilizing almost 50 years of professional experience in engineering, manufacturing, tool-making, and space-age precision, Chris Dunn has provided an in-depth analysis of ancient Egyptian statuary, temples, and manufactured artifacts that has never been presented previously. This outstanding book, supremely well researched, amply illustrated, and complete with detailed photographs, will be cited as a major paradigm shift and reference source in the field for many years to come.”


“Admirers of Egyptian art and architecture are most fortunate that Christopher Dunn directs his experienced engineer’s eye toward the Egyptians’ ancient stonework. By noticing the most minute details he reveals sophisticated craftsmanship and immense significance for all areas of Egyptology. Mathematicians will appreciate the amazing three-dimensional geometry made manifest in very hard stone. Dunn points the way for geometers to uncover sharper, more accurate analyses of the proportions of Egyptian design. This book is an important contribution to scientific scholarship by showing how archaeology can firmly rest on a measurable foundation.”


“In this book, Christopher Dunn has brought to the field of Egyptology a new approach, which has been needed for decades. His ability as an engineer and master craftsman has given him the insight to discover ancient technologies and techniques that have been missed by traditional Egyptologists. This book is a paradigm change for the way of thinking about our ancient history and ancestors. I highly recommend this beautiful illustrated book to both academic and alternative researchers and for anyone interested in new ways of thinking about our ancient past.”


“As with Newton and the apple, Chris Dunn got a vision when visiting Egypt. His engineering background allowed him to unleash incredible facts, and thanks to this highly detailed book, we can now share the same marvels.”


“If you want to see the precise high technologies ancient Egyptians really had, read this book. It is a serious donation to Egyptian legacy and an opus for the future of this planet.”


“I believe, as Chris Dunn superbly details in this book, that ancient Egyptian sculptors and architects were so precise and their works so monumental that they must have used sophisticated technology, probably hidden in their time and now lost to ours.”


Shifting Paradigms

In the mid-1990s I was co-founder of a NASDAQ-listed software company in Albuquerque, New Mexico, which specialized in presenting digital data in a unique 3D immersive graphical environment (also called virtual reality, or VR). One particular time, we showed the results of our VR work to an undersecretary of the US Department of Transportation — an abstract presentation of rather mundane DOT traffic data from various road intersections around the nation. Because of the intuitive display system, without any interpretation training at all, the undersecretary was able to see patterns, anomalies, and trends in his data, striking evidence of unexpectedly massive distortions and errors, perhaps even fraud, resident in his measurements but unseen before.

So shocked was the bureaucrat that he told the audience of several hundred technophiles, “I will never be able to look at my new data the same way again. Not only that, I wont even be able to look at my old data the same way.” From this honest and open spontaneous reaction, I coined the saying, “A paradigm shift not only changes the future, it changes the past!”

What researcher Christopher Dunn has accomplished in Lost Technologies of Ancient Egypt and in his previous work, The Giza Power Plant, is more than a paradigm shift; it is more of a paradigm seismic event. Because once a person with a manufacturing or machining background — engineer, technician, machinist, artisan — reads and understands what Dunn has discovered and analyzed in ancient Egyptian stonework, that person will never look at ancient Egyptians the same way ever again. That reader will become skeptical of portrayals of ancient Egyptians as primitives in any sense. That reader will begin to analyze every new Egyptian archaeological discovery, to see what else conventional Egyptologists have overlooked. That reader will become part of the new paradigm.

In these pages, Chris Dunn demonstrates an underlying system of incredible precision in the machining, layout, and positioning of both individual objects and groups of features, ranging from the toolmark details in the “Rose Red Rosetta Stone of Abu Roash” to the symmetries of the giant heads of Ramses at the temples in Luxor, to the layout of the column capitals of the Great Hypostyle Hall at Denderah, to the base of the Great Pyramid itself. Thanks to this work, the modern reader sits back in awe and admiration of the Egyptian geniuses of five thousand years ago. The ancient artifacts contain amazing messages, but the stones cannot speak for themselves. This book speaks for them.

In November 2008, I accompanied Mr. Dunn and others to what some have called “the Lost Pyramid” at Abu Roash, some ten kilometers northwest of Giza. I was anxious to see the rose-colored granite piece that the author had described to me years before, anticipating seeing the compound radial cuts and distinguishing toolmarks. I was not disappointed. To any technophile, this one cut stone exhibits mute arguments against primitive tools and primitive peoples. More than any other artifact, it embodies an ancient “language” that still speaks to modern engineers. I immediately dubbed it the "Rose Red Rosetta Stone of Abu Roash.”

I called the stone a “Rosetta” because its discovery reminded me of another paradigm-changing artifact: in 1799, Napoleons soldiers found a curious object embedded in a wall of an Egyptian village. Their original report, “A Report on a Stone Found in the Village of Rosetta,” describes a black rock slab inscribed with three languages, one of them being ancient Greek, the others the unknown Egyptian hieroglyphic writing and the cursive or “demotic” Egyptian writing. Reading the Greek portion, the antiquarian Champollion was able to translate the names of the Pharaohs — written within cartouches — and thence the rest of the hieroglyphic writing itself. He opened up an eventual understanding of the millions of carved figures decorating the ancient temples and tombs of the Nile. Nobody would ever again look at the hieroglyphic carvings as mere magical, mystical figures, but would read the translations of experts who deciphered those cuts and reliefs, uncovering the lost history of Egypt.

The Rosetta stone thus facilitated a change in the worldview of moderns who looked back at ancient Egyptians. Nothing would ever be the same. I maintain that this book has accomplished a similar feat, every bit as meaningful to an understanding of ancient Egypt, if not more so. Once understood, Dunn’s discoveries will forever change the perception of the serious researcher.

In a similar manner to Champollion reading ancient Greek and comparing it to the unknown hieroglyphic figures, researcher Christopher Dunn was able to “read” the machine-cut tool marks on the Abu Roash stone and compare them to those made by modern tools capable of the same operations. With years of experience and a trained eye for such details, and armed with the proper paradigmatic perspective, Dunn was able to recognize at once what it meant to produce a stone with a curved cut some 37 feet in diameter, and to reproduce that cut in small, uniform steps across a three-foot width — over 700 nearly identical radial tool cuts! This feat is simply not achievable by human hand alone, using any known tools.

Such toolmarks require at the very least a large saw blade or cutting tool, and sophisticated fixtures to produce the steps between cuts. To suggest that the primitive tools ascribed to the ancient Egyptians could have produced anything like these markings is ridiculous. In my opinion, this machined stone by itself demonstrates the existence of sophisticated tooling that did not exist again until the 1900s.

To the modern engineer, machinist, or toolmaker, the toolmarks on the Rose Red Rosetta Stone of Abu Roash are proof enough that the ancient Egyptians possessed technologies not replicated until the twentieth century — if even then. But Lost Technologies of Ancient Egypt shows more examples, each of which have similar impact — the Ramses heads in Luxor, the carvings and columns at Denderah — further reinforcing the genius of the ancient machinists, engineers, designers, and planners. Taken together, they represent arguments in stone that refute current Egyptological conclusions.

When civilization fails for any reason, metals of all kinds become precious commodities. They become knives, spear points, scrapers, fishhooks, even plows. Ancient Egypt underwent numerous upheavals caused by droughts, earthquakes, civil wars, religious strife, and foreign invasions. During the times of collapse, the advanced metal tools that the ancient Egyptians used were probably disassembled, cut apart, or melted down. What wasn’t immediately used would corrode and disappear after thousands of years. And perhaps some other advanced technology was also employed, the remnants of which we wouldn’t recognize today.

Large saw blades and other machine tools, if not secreted away from armies, earthquakes, floods, and mobs, would not endure very long. Over the millennia, few metal objects from our own time would survive or be recognizable. Life After People, a popular cable television show that debuted in 2009, shows example after example of the deterioration of manmade objects after years, merely because of lack of maintenance. In five thousand years, approximately the timespan estimated in Lost Technologies of Ancient Egypt, almost nothing of today’s technology would be left. In a world of resourceful (and destructive) human beings, the devastation would be much worse than Mother Nature alone could cause; marauding bandits and nomads would re-use, recycle, or otherwise destroy even our ubiquitous automobile engine blocks and our porcelain toilet bowls!

It may be that future archaeologists will one day uncover an untouched ancient factory or workshop under the sands or in the caves of Egypt, a place that was purposefully hidden away from destructive recycling, a place that would show us exactly what the ancients used and how. Such a discovery would be the equivalent of the unexpecedly sophisticated two-thousand-year-old Greek computational mechanism, the Antikythera Device! But to recognize their finds as evidence of ancient technologies, those future discoverers must have minds that are opened to the possibilities that Christopher Dunn has been the first to reveal. Otherwise, that advanced machine shop of the ancients could wind up stored in unnumbered boxes in the basement of the Egyptian Museum in Cairo, labeled merely as “funerary objects.”

Recent discoveries at the archaeological site Göebekli Tepe, in Turkey, indicate that twelve thousand to thirteen thousand years ago, so-called primitives were erecting T-shaped monuments as tall as six meters, ranging in weight from ten to fifty tons, perhaps building a Neolithic cathedral of sorts. Many of these stone pillars exhibit carvings of wildlife and even some human-shaped reliefs. For unknown reasons, the site was deliberately buried approximately ten thousand years ago. Because this site can be dated as existing prior to previously established dates for the beginnings of agriculture and urbanization, not to mention cooperative construction of stone monuments, we can readily believe that conventional chronology is at the least incomplete, if not wholly inaccurate. We see that every new archaeological discovery pushes back civilized development further and further into the past, never in the opposite direction.

So here we have evidence of moving massive stones and carving them in intricate detail dating earlier than 10,000 BCE — thousands of years before the ancient Egyptians were believed to have begun the stone machining that the author examines in this volume and in his previous works. Several thousand years passed between the time of Göebekli Tepe and that of the Egyptian First Dynasty, millennia in which artisans and engineers of ancient times could have perfected their craft, invented their complete suite of enabling tools and supportive technologies, and eventually emigrated to the Nile Valley, becoming part of the incipient civilization emerging there. With centuries of experiment and practice, those who worked in stone could have kept their knowledge secret, offering their finished products to leaders, priests, and the wealthy. As Dunn points out in this volume, even today trade secrets and proprietary knowledge are closely held, even in an educated world-wide civilization with widespread literacy and training. In ancient times the impulse to secrecy may have been even more necessary for survival.

Alas, the human beings who worked the Rose Red Rosetta Stone of Abu Roash, who machined the statues of Ramses, the columns of Denderah and the stones of the pyramids, were more fragile and evanescent than the mighty tools they employed in their work. If tools of metal are lost in war or natural catastrophe, their flesh and blood designers and operators are even more subject to the vagaries of Fate — disease, injury, wounds, and famine can take away technicians, inventors, planners, and managers, while leaving behind marvelous tools fit only for destruction by desperate people ignorant of their value.

If the knowledge of a specific task, the operation of a given machine tool, or the procedure for laying out vast projects is resident in just a few people, maybe just one, then the loss of that person or group means the knowledge is gone forever, unless it is recorded. This is an eternal problem, not limited to the ancient Egyptians of five thousand years ago. As a modern example, in 1992 while working at the White House Science Office, I invited to a meeting there a person from the National Science Foundation. Although only peripheral to the agenda, this older scientist regaled us with a tale of a lost technology of modern times, namely how to start up the engines of the Saturn V rocket that took American astronauts to the Moon from 1969 to 1972. Incredibly, this leading scientist averred that no one was alive who knew how to start up the engines on the largest rocket ever flown. No one had written down the standard operating procedure, and the rocket men who had developed the technique had all passed away.

So in 1992 CE or 1992 BCE or further back in time, we can find sufficient examples to demonstrate that technologies are not always lost as a result of conspiracy. Ordinary human pride, greed, stubbornness, selfishness, and even carelessness, can account for much of our loss.

In two groundbreaking works, author Christopher Dunn has opened our eyes that ancient Egyptians, and maybe others in the past, designed, planned, laid out, and precisely machined stone statues that would be difficult to reproduce even with todays manufacturing technologies. As the first person to uncover and develop this new paradigm, he has gone on to investigate other ancient Egyptian artifacts, temples, tombs, and pyramids using this new way of looking at information. He has retrieved knowledge that all before him have overlooked, save Flinders Petrie, whose interest was not primarily proving advanced ancient technology, merely commenting upon interesting findings. A new way of looking at old data could bring new respect to ancient civilizations that left magnificent ruins in a still-troubled part of the world. As we understand more about the origin of Egyptian temples and pyramids, we find a way to bridge the past and the present, a way to look for still other revelations that affect us as human beings.

Recognizing the Brilliance of Ancient Manufacturing

No one can be a great thinker who does not recognize that as a thinker it is his first duty to follow his intellect to whatever conclusions it may lead. Truth gains more even by the errors of one who, with due study, and preparation, thinks for himself, than by the true opinions of those who only hold them because they do not suffer themselves to think. – JOHN STUART MILL, ON LIBERTY

As a lawyer trained in the areas of evidence and the nature of proof, I have witnessed firsthand the disagreements that occur in the arena of ideas. Sometimes these disagreements make their way into a courtroom, where a trial is held and a judgment made as to which opinion carries the weight of evidence — evidence that ultimately convinces a judge and jury. The court reaches a decision in favor of the party or parties that presented that convincing evidence.

Over the course of this book, Chris Dunn presents evidence that raises a multitude of challenging questions, introducing new ideas and opinions about the history of craftsmanship in Egypt. This work calls into question established paradigms and theories that have, for many decades, formed the basis of academic studies in schools and universities around the globe and in volumes that occupy the shelves of virtually every library. But first, let me describe how I came to be involved in this debate.

Leaving the formal practice of law in the late 1980s, I have, in the ensuing two decades, become a manufacturer, more specifically a fabricator of sheet metal components for gas turbine engines at Danville Metal Stamping Co., Inc., located in Danville, Illinois, USA. It was here that I first met Dunn, upon my arrival at Danville Metal in 1988. He preceded me at the company by a couple of years and was then serving in the capacity of laser engineer. He later became a manufacturing engineer and, in 1995, brought his manufacturing and engineering skills, as well as his judgment and insight, to the post of Human Resources Manager. As President and CEO, I devote a significant amount of time to human resources and, consequently, my contact with Dunn increased dramatically.

At that time, I had little background or particular interest in Egypt, the pyramids, or ancient technologies and civilizations. Nonetheless, like most humans, I had a natural curiosity about how things are made or done and why. My curiosity then turned toward the subject that Dunn had spent the past twenty years studying in his spare time, and I was impressed by the enthusiasm and sense of wonder he had for it.

Over breakfast after a Sunday walk, Dunn would discuss his thoughts on ancient technologies. Those discussions were often supplemented by a photograph or other visual aid, such as an engineering drawing or a sketch on a napkin or scrap of paper. We would also discuss the online controversies that swirled around his comments, theories, and questions raised in his first book, The Giza Power Plant. Dunn’s analysis did not stop there; he instead applied the criticism he received to improve his methods and collect further evidence.

In February of 2006, Dunn took another of his many trips to Egypt, this time with a tour group that visited a number of temples in Upper Egypt. Although he had first visited those temples in 2004, his exposure had been brief and he was interested in more closely inspecting temple artifacts, especially in the Luxor Temple. This new expedition took Dunn deeper into and beyond the issues he had explored previously. He returned from the trip with a new and elevated interest in the accomplishments of the ancient Egyptians in the temples, particularly the statuary. His observations in the temples presented a new frontier of amazing feats, raising questions that were complementary to observations he had made in connection with granite boxes and other aspects of construction in the pyramids.

In April and May of the same year, I took the opportunity to travel with Dunn to witness in person what I had only examined as photographic evidence. This included many looks through the viewfinder of his camera equipped with a telephoto lens and then verifying the results captured by the camera.

From personal observation, I can verify that in this book Dunn has been true to the evidence he observed. As an engineer, Dunn was able to analyze his observations with CAD/CAM programs and geometrical analysis unavailable or incomprehensible to the average observer. Among other things, with advances in digital imaging, a technology used daily in manufacturing, his computer-assisted analysis afforded him the ability to see attributes that could not be seen or analyzed with the naked eye even in the presence of the original artifact.

Using his extensive skills and his tools as an engineer and a toolmaker and bringing to bear his decades of experience in manufacturing, Dunn was relentless in assessing what he could reach and, through his camera lenses, preserving that which he saw. He also used his camera to capture what he could not necessarily reach and was thoughtful and creative in his approach. As the reader will witness in the pages that follow, Dunn thinks well in three dimensions and understands thoroughly the consequences of a particular test, comparison, or view.

After our visit to the temples in 2006, Dunn studied his photographs and detected in the statues certain features that resembled tool marks — the kind of tool marks that a craftsperson or engineer would recognize. Realizing that he had focused on collecting geometric information and neglected to look for evidence of tool marks, another trip was planned and taken in November of 2008 to further authenticate and more finely focus on what his previous photographs indicated. On this trip I was able, through Dunn’s camera, to see the tool marks on the cheek of one of the Ramses in the Temple at Karnak, even though the head of that statue was some 45 feet in the air. I was later able to examine the resulting photograph, as can the reader later in this book.

I vividly remember my first (and then every subsequent) visit to the Luxor Temple. Although smaller than the nearby Temple at Karnak, the Luxor Temple is impressive. The different areas of the Temple provided an interesting variety of architecture from the hall of the Ramses to the colonnade to the plaza to the inner temple. Each had something different to offer and yet they harmoniously fit together. The imposing Ramses statues hewn out of huge solid blocks of granite, the immense columns, and the fact that the Temple, its contents and its surrounding have existed for thousands of years caused me to wonder about the influence it had on the civilization that built it. From these thoughts, my mind was opened to a new awareness.

As I am confronted with the evidence, both in Dunn’s book and from my own personal observation, I find myself wondering, among other things, how the technology of the ancient Egyptians that allowed them to carve and shape stone as they did was applied in other areas of their society, such as healthcare and dentistry for example. In our socety, advancements in one area of technology are quickly spread to other areas in which those advancements might apply. Wouldn’t the ancient Egyptians have done the same?

While my background as an attorney and a manufacturer qualifies me to evaluate Dunn’s work objectively, I am still awestruck by what he has revealed in his studies and by the disparity between his findings and the understanding I gained in the course of my traditional education on the subject. If, metaphorically speaking, truth lies at the heart of an onion, I have witnessed firsthand as Dunn peeled away layers of that onion to get closer to the heart of technologies employed in ancient Egypt, revealing previously unaddressed questions. While the most obvious and prominent of those questions is how these ancient artifacts were made to exhibit such remarkable geometry and precision, the second most obvious that follows quickly on the heels of the first is why.

At this time, there are no certain answers to these questions, and it is human nature to fill the void of the unanswered question with something. Those who ignore questions because the answers are not apparent are disingenuous. I am reminded of this quotation from John Stuart Mill in Considerations on Representative Government: “From despairing of a cure, there is too often but one step to denying the disease; and from this follows dislike to having a remedy proposed, as if the proposer were creating a mischief instead of offering relief from one.”

A skeptic is defined by Webster's as “a person who questions the validity or authenticity of something purporting to be factual,” while the same dictionary defines cynical as “distrusting or disparaging the motives of others.” In his work, Chris Dunn invites us all to be skeptical of things that we may have never really questioned while, at the same time, he invites rigorous skepticism of his own observations. This skepticism is healthy and helpful. It is not cynicism, however. It is not contempt for the theories or ideas of others or for those who proffer those theories or ideas. It is a questioning and a testing of ones own ideas and theories as well as those of others. In reading and contemplating the pages that follow, I entreat the reader to be skeptical but not cynical.

In exercising skepticism while reading Dunn’s work, also bear in mind this quotation from the Wizard in the play “Wicked”: “Back where I come from we believe all sorts of things that aren’t true … we call it history.”

Perhaps a more famous Winston Churchill quote, “history is written by the victors” should be considered. The history of Egypt traditionally taught in the west has, for the most part, been written by western scholars who followed on the heels of their armies. I am confident that the obvious sophistication of the ancient Egyptians revealed in this book will, in due time, prompt western scholars and others around the world to reexamine what has been written about ancient Egypt and to consider what else the citizens of that ancient civilization, by whatever means, accomplished.

Tell me, Mr. Hoover, what are your interests?
Madam, I am an Engineer.
Really? I took you for a gentleman.


It is possible that Mr. Hoover’s confused lady acquaintance had the wrong impression of what an engineer does, since a train driver is also known as an engineer. There are mechanical engineers, electrical engineers, materials engineers, computer engineers, construction engineers, quality engineers, and safety engineers. And all may not be considered gentlemen — many you may meet will be ladies. Each engineer works in a specialized field, and within those particular disciplines are subgroups that work in myriad industries that form the fabric and backbone of modern civilization. Of themselves and their machines, the life of an engineer is frequently punctuated with Scotty’s Star Trek lament, “Can’t take much more o’ this, Captain!”

Perhaps unbeknownst to you, the engineers’ labors have a direct affect on your daily life. For instance, you have just arrived in the office, hung up your coat, and poured yourself a cup of your favorite morning beverage. An army of engineers and artisans worked to create the technology that has allowed your morning ritual to happen. Crafted into the car, train, or bus and the elevator that carried you to your destination are the labors of the modern artisan. At some location miles away, perhaps on another continent, the skillful eye and hands of artisans guided the tools that created the coffee maker and processed the coffee.

The Industrial Revolution of the 1800s propelled Western civilization forward in terms of labor-saving devices. Around this time, many of the machines that are now used in manufacturing were either invented or improved. Yet the most basic of machines, the lathe, has been around in one form or another for centuries — originally in the form of a potter’s wheel. Its development as an efficient metal-cutting machine grew from the invention of the steam engine, which powered everything from textile mills to Stephenson’s Rocket, the first steam locomotive to convert linear motion to rotary motion and use that rotary motion to propel itself along two rails at the dizzying speed of twenty-five miles per hour.

In the past sixty years, technology has advanced rapidly in directions that many people, except science fiction writers and futurists, could not even have imagined possible. Discoveries and innovations in the field of physics have introduced new patterns of thought in the minds of scientists and inventors. Like legs on a centipede, branches of science, engineering, and manufacturing, along with the creative genius of gifted artists who are now an essential part of the design of functional products, move forward, independently and in unison, each drawing on the other for inspiration and survival.

Three hundred years before the Industrial Revolution was in full swing, geniuses arose among their peers and made their mark, adding to the prosperity and understanding of future generations. The genius of Leonardo da Vinci, Copernicus, and Galileo is well known. During this period, mathematicians, astronomers, and philosophers laid the groundwork for the pursuit of scientific inquiry and changing the worldview of humanity and its place in the universe. With its genesis in the 1500s, what is now known as the Scientific Revolution fought against the church and superstitious beliefs to create the foundation of modern science. The heliocentric theory of Nicolaus Copernicus shattered many beliefs of the earth’s preeminence in the universe, and the Catholic church, which opposed such heresy, fought tooth and nail to stop the rush of intellect that ultimately reshaped our beliefs about nature and ourselves. Rene Descartes, a devout Catholic himself, cut through the confusion that had reigned for so long with a remarkably simple philosophy that to us is a part of life, but in his day was counter to the philosophy of the church, for it would ultimately challenge the church’s own philosophy and teachings. In “Discourse on the Method of Rightly Conducting the Reason and Seeking for Truth in the Sciences,” Descartes sets forth three guidelines that he followed in his own work:

quote big

The first of these was to accept nothing as true which I did not clearly recognize to be so: that is to say, carefully to avoid precipitation and prejudice in judgments, and to accept in them nothing more than what was presented to my mind so clearly and distinctly that I could have no occasion to doubt it.

The second was to divide up each of the difficulties which I examined into as many parts as possible, and as seemed requisite in order that it might be resolved in the best manner possible. The third was to carry on my reflections in due order, commencing with objects that were the most simple and easy to understand, in order to rise little by little, or by degrees, to knowledge of the most complex, assuming an order, even if a fictitious one, among those which do not follow a natural sequence relatively to one another.1

From the birth of the Scientific Revolution to the Industrial Revolution the knowledge of the world has advanced at a rapid pace. Up until today, this advancement has spanned five hundred years. Within that time we have gone from an agrarian society with a much lauded, simple, pastoral existence to a complex industrial society with products that were undreamed of when the creator of the world’s first successful locomotive, Robert Stephenson, cried out, “full steam ahead!”

Punctuating each stage of civilization’s development are major building projects that by necessity or demand incorporate the state-of-the-art building construction of their period. The landscape of the ancient world is dotted with fabulous structures that are breathtaking in their complexity. The Egyptians and Mayans had their pyramids and temples. The Hindus crafted elaborate temples throughout Asia. The Greeks built the Parthenon, and the Babylonians constructed the Jupiter Temple and the fabled Hanging Gardens. The Romans made their mark all over their world, with engineering geniuses guiding the construction of their famous roads, the Coliseum, and numerous temples and viaducts, while Roman sculptors guided their chisels over marble and alabaster, giving it physical presence and beauty.

With the exception of artifacts such as the mysterious Antikythera Mechanism, an astronomical computer found by fishermen on the sea floor near the island of Antikythera in 1901, the development of technology in the ancient world seems to have clear origins and is fairly well understood.

Going back yet further in time, another deep mystery lies in the question of how the ancient Egyptian civilization could have lasted for three thousand years without improving the tools used to quarry and shape stone to near perfection. Since 1984, when Analog magazine published my article “Advanced Machining in Ancient Egypt?” controversy on this subject has persisted. The article proposed that the ancient Egyptians were more advanced than previously believed and that they used advanced tools and methods to cut granite, diorite, and other difficult-to-work stone. It does not seem credible that brilliant architects and engineers would continue to use stone tools and copper chisels for three millennia.

Following this article, I have received input from many kind people from different walks of life. Though much of the feedback I have received has been extremely positive and supportive of the idea that ancient cultures were more advanced than classical archaeology has supposed, there has been some criticism from those who believe that I went too far with my conclusions because I made the mistake of imposing a modern engineer’s viewpoint on an ancient civilization, thereby ignoring its cultural origins, and disrespected the Egyptians’ heritage.

In fact quite the opposite is true. Anyone who suggests that the ancient Egyptians were more advanced actually shows more, not less, deference and respect to their civilization. Such a statement does not diminish their culture in any way. Rather, such a suggestion would elevate the Egyptians’ status in the world. The cultural assumptions that are disturbed most by the idea of an advanced Egyptian race in prehistory lie in the libraries and halls of Western countries and the belief system that has been generated by generations of Western scholars — beginning with Herodotus. It is our own culture’s chauvinistic view of Egypt that threads throughout our history books.

Studies made by archaeologists, historians, and Egyptologists over the past five hundred years have essentially provided us with the modern, conventional view of ancient Egypt. This is an area of intense interest to engineers — such as myself — who find in Egypt a language with which we are familiar. This is the language of science, engineering, and manufacturing. Our counterparts in that ancient land left future generations of scientists, engineers, architects, and those who take their instructions and shape materials to their specifications, with a difficult challenge. This challenge is to recognize what they created and provide evidence-based, reasonable answers that give the ancient engineers credit for what they achieved. With their works, ancient engineers, perhaps unwittingly, created a sort of Mecca for modern engineers and technologists. The engineers and technologists that have taken this “pilgrimage” have discussed many theories, but always at the end we come up short of confidence that the theories are actual truth.

The ancient Egyptians who built the pyramids and temples, who crafted monumental statues out of igneous rock, were thinking with the minds of architects, engineers, and craftspeople. Were ancient archaeologists responsible for the legacy they left us? Without the advice of modern Egyptian architects, engineers, and craftspeople, are today’s Egyptian archaeologists missing something? Are modern interpretations of the awesome feats of the ancient Egyptians irrelevant in providing new and powerful information about this ancient culture? Are the thoughts and conclusions of Western writers and travelers who stood in front of the Great Pyramid one hundred years ago (or some forty-five hundred years after it was built) more intrinsically linked to the ancient Egyptian mind than those who come after them, a century or more later? What can be described as a “modern perspective?” In his time, Herodotus would surely have been considered modern. So were Egyptophiles Petrie, Marriette, Champollion, and Howard Carter — each in possession of a modern mind that was clothed in a fabric of prejudices and stereotypes that existed within their own culture.

When it comes to completely understanding the ancient Egyptians’ level of technological prowess, there can be no final conclusion. What is left to study today is a mere skeleton of what existed at the time of the ancient Egyptians. This skeleton survives as highly sophisticated and precisely crafted sedimentary and igneous rock. It is my belief that the clothes we have placed on this skeleton are mere rags compared to what should be there. I have proposed in the past that higher levels of technology were used by the ancient Egyptians, but you will find in this book that I have rejected some ideas and cast doubt on all my previous assertions as to the level of technology they enjoyed. At the same time, I cast doubt on the methods of manufacture that Egyptologists have asserted were used to build the pyramids and the glorious temples in Egypt. These methods are primitive and include stone and wooden mallets; copper chisels; tube drills and saws; and stone hammers for quarrying, dressing, and sculpting hard igneous rock. Nobody can claim that they know what was in the minds of the ancient Egyptians. All we have are their works: “By their works, ye shall know them.”*

This book is about the Egyptians’ works, but before understanding the manufacturing and building methods, it is necessary to understand the full scope of each work — exactly what it is we are studying. In the following pages I present another view of ancient Egyptian artifacts: the view of a modern craftsman and engineer made possible through the use and knowledge of modern technology.

After I describe each work, we will examine the methods of construction that have been proposed by Egyptologists and discuss some of the arguments against and for considering other methods that are more advanced. It is my sincere wish that the artifacts are respected and understood for what they are. They are priceless treasures and would have astronomical value if produced today using modern tools. Because they are encoded with the knowledge of life on this planet in prehistory and hold a powerful message for future generations, their worth in monetary terms is unfathomable. Their value in raising awareness and dispelling cultural bias, even while short of real answers, cannot be calculated in monetary terms.
