The mystery of how the Egyptian pyramids were built has puzzled scientists for centuries. These tombs for the pharaohs, built over 4,000 years ago, still stand today, with more than 100 in existence. The Great Pyramid of Giza, the largest of them all, was originally 147 meters (482 feet) high and made up of around 2.3 million stone blocks, each weighing between 2.5 and 15 tonnes. This incredible engineering feat required the stones to be transported to the construction site, lifted, and set into place using the technology available at the time.
Recent research has shed light on some aspects of this ancient construction. The most widely accepted theory is that ramps were used to pull the heavy stones up, supported by the discovery of sloped structures near certain pyramids. Dr. Eman Ghoneim, a Professor at the University of North Carolina Wilmington, believes that the debate on how these immense blocks were lifted to such great heights continues among scientists.
Dr. Roland Enmarch, a Senior Lecturer in Egyptology at the University of Liverpool, and his team made a groundbreaking discovery in 2018. They found ramps cut into the rock at the Hatnab quarry in eastern Egypt, suggesting that similar ramps may have been used in the construction of the Great Pyramid. This challenges previous estimates of the slope needed for these ramps and provides new insights into the building techniques of the ancient Egyptians.
Construction Schedule
Planning and construction of the pyramids were likely time-sensitive, as they usually began at the start of a king’s reign. The Great Pyramid of Giza, for example, is believed to have taken 20 years to complete. Frank Muller-Römer, an archaeologist in Munich, has developed a theory involving the use of multiple ramps along the outside of the structure to speed up the construction process.
Various other techniques such as levers, cranes, and pulleys may also have been utilized in pyramid construction. A recent study proposed a hydraulic lift system that could have been used in the construction of the Step Pyramid of King Djoser. However, some experts doubt the feasibility of such a system based on archaeological evidence.
To gain a deeper understanding of the internal structure of the Great Pyramid of Giza, researchers are using advanced scanning techniques. The ScanPyramids project aims to uncover hidden spaces within the pyramid by tracking muon particles passing through its walls, potentially revealing new insights into its construction.
Identifying Supply Lines
Another aspect of pyramid construction being explored is how workers and materials were transported to the site. Recent research has focused on locating ancient Nile tributaries and canals that may have been used for transportation. Satellite images and ground surveys have revealed new information about the transportation networks that supported the construction of the pyramids.
Excerpts from ancient records have also provided valuable insights into the construction process of the pyramids. Fragments of logbooks detailing the activities of workers at the Great Pyramid of Giza have been discovered, dispelling myths of alien involvement and highlighting the logistical challenges faced by the builders.
