New theory emerges about how ancient Egyptians built pyramids

A recent study by Paleotechnic, an archaeological research institute in Paris, proposes a novel theory on how the ancient Egyptians constructed their pyramids.

The research suggests that the massive stones were lifted using a "hydraulic lift" mechanism, powered by water from a nearby moat, which allowed the structure to rise as each new layer was added.

“Ancient Egyptians are famous for their pioneering and mastery of hydraulics through canals for irrigation purposes and barges to transport huge stones,” the authors of the study said. “Ancient architects likely raised the stones from the pyramid centre in a volcano fashion using the sediment-free water.' 

This theory emerged from an analysis of satellite images and historical records of Egypt’s oldest pyramid, the Stepped Pyramid of Djoser, which dates back nearly 4700 years. The pyramid is known to have a large central shaft, previously a mystery in terms of its purpose.

The researchers also examined Gisr el-Mudir, a nearby ancient stone structure. They propose that this structure might have functioned as a dam, collecting rainfall and channeling it through a system of pipes towards the pyramid. Once the water reached the pyramid’s core, it would have surged upwards through the central shaft, much like magma in a volcano.

This upward force could have supported a floating platform, likely constructed from wood, capable of lifting stones weighing up to 100 tonnes.

This innovative theory provides a new perspective on the engineering marvels of ancient Egypt and contributes to our understanding of their impressive architectural achievements.
