Engineers Found Evidence of Hydraulics in an Ancient Pyramid, Solving a 4,500-Year-Old Mystery



Hello1  Archeology is finally catching up to using hydraulics to build pyramids, as i have argued for decades.  I had focused on the Great Pyramid which offered a number of impossibilities to eliminate.  as i have posted, using hydraulics, i can build it on time and on budget.

Certainly the Step pyramid is exactly where to start your research.  that is where they mastered the art.

And they obviously kept right on building until finished.  quite the trick.

Engineers Found Evidence of Hydraulics in an Ancient Pyramid, Solving a 4,500-Year-Old Mystery


See how Egyptian engineers might have used water to shape history’s greatest monuments.

A new study suggests that the first of seven key pyramids in Egypt, the Step Pyramid of Djoser, was built using a hydraulic lift.

Dated to about 4,500 years ago, this would move up the introduction of major hydraulic systems from previous beliefs.

The landscape, waterways, and interior architecture of the pyramid all point to the hydraulic system.

Hydraulic mechanics may have indeed been the driving force behind the construction of ancient Egyptian pyramids.

In a recently published study in PLOS ONE, scientists concluded that the Step Pyramid of Djoser in Saqqara, Egypt—believed to be the oldest of the seven monumental pyramids and potentially constructed about 4,500 years ago—offers a remarkable blueprint for hydraulic engineering.

The hydraulic-powered mechanism could have maneuvered the oversized stone blocks forming the pyramid, starting from the ground up. The research team says the Step Pyramid’s internal architecture is consistent with a hydraulic elevation mechanism, something that’s never been reported before at that place or in that time.





By lifting the stones from the interior of the pyramid in what the authors call a “volcano fashion,” the water pressure from the hydraulic system could have pushed the blocks into place. If proved out, this research shows the Egyptians had a powerful understanding of advanced hydraulic systems well before modern scholars believed they did. That begs the question: Was this the first major use of the system, or had it been in play previously?

No matter the answer, pulling it off at the Step Pyramid would have been no easy feat.


The team believes that based on the mapping of nearby watersheds, one of the massive—and yet unexplained—Saqqara structures, known as the Gisr el-Mudir enclosure, has the features of a check dam with the intent to trap sediment and water. The scientists say the topography beyond the dam suggests a possible temporary lake west of the Djoser complex, with water flow surrounding it in a moat-like design.

As a Nile tributary fed the area, a dam could have created a temporary lake, potentially linking the river to a “Dry Moat” around the Djoser site, helping move materials and serving the hydraulic needs.

“The ancient architects likely raised the stones from the pyramid center in a volcano fashion using the sediment-free water from the Dry Moat’s south section,” the authors write.

In one section of the moat, the team found that a monumental linear rock-cut structure consisting of successive, deep-trench compartments combines the technical requirement of a water treatment facility—and a design still often seen in modern-day water treatment plants—by including a settling basin, retention basin, and purification system.

“Together, the Gisr el-Mudir and the Dry Moat’s inner south section work as a unified hydraulics system that improves water quality and regulates flow for practical purposes and human needs,” the authors write. The team believes the water available in the area was sufficient to meet the needs of the project.

“Ancient Egyptians are famous for their pioneering and mastery of hydraulics through canals for irrigation purposes and barges to transport huge stones. This work opens a new line of research: the use of hydraulic force to erect the massive structures built by Pharaohs.”
