Hidden chamber discovered in Great Pyramid
CAIRO — Scientists say they have found a hidden chamber in Egypt’s Great Pyramid of Giza, in what would be the first such discovery in the structure since the 19th century and one likely to spark a new surge of interest in the pharaohs.
In an article published Thursday in the journal Nature, an international team said the 30-yard void deep within the pyramid is situated above the structure’s Grand Gallery, and has a similar cross-section.
The purpose of the space is unclear, and it’s not yet known whether it was built with a function in mind or if it’s merely a gap in the pyramid’s architecture. Some experts say such empty spaces have been known for years.
“This is a premier,” said Mehdi Tayoubi, a co-founder of the ScanPyramids project and president of the Heritage Innovation Preservation Institute. “It could be composed of one or several structures. … Maybe it could be another Grand Gallery. It could be a chamber, it could be a lot of things.”
The scientists made the dis- covery using cosmic-ray imaging, recording the behavior of subatomic particles called muons that penetrate the rock similar to X-rays, only much deeper.
Their paper was peerreviewed before appearing in Nature, an international, interdisciplinary journal of science, and its results confirmed by other teams of scientists.
Chances of the space containing treasure or burial chambers are almost nil, said Aidan Dodson, an Egyptologist at the Uni- versity of Bristol, but the discovery helps shed light on building techniques.
“The pyramid’s burial chamber and sarcophagus have already been discovered, so this new area was more likely kept empty above the Grand Gallery to reduce the weight of stone pressing down on its ceiling,” he said, adding that similar designs have been found in other pyramids.
Egypt’s former antiquities minister and famed archaeologist Zahi Hawass, who has been testing scanning methods and heads the government’s oversight panel for the new techniques, said that the area in question has been known of for years and thus does not constitute a discovery. He has long downplayed the usefulness of scans of ancient sites.
“The Great Pyramid is full of voids. We have to be careful how results are presented to the public,” he said, adding that one problem facing the international team is that it did not have an Egyptologist as a member. He said the chamber was likely empty space builders used to construct the rooms below.
The pyramid also is known as Khufu’s Pyramid for its builder, a 4th Dynasty pharaoh who reigned from 2509 to 2483 B.C. Visitors to the pyramid, on the outskirts of Cairo, can walk, hunched over, up a long tunnel to reach the Grand Gallery.
Scientists involved in the scanning called the find a “breakthrough” that highlighted the usefulness of modern particle physics in archaeology.
“It was hidden, I think, since the construction of the pyramid,” Tayoubi added.
