A robot explorer has revealed ancient markings inside a secret chamber at Egypt’s Great Pyramid of Giza.
The markings, which have lain unseen for 4,500 years, were filmed using a bendy camera small enough to fit through a hole in a stone door at the end of a narrow tunnel.
It is hoped they could shed light on why the tiny chamber and the tunnel — one of several mysterious passages leading from the larger King’s and Queen’s chambers — were originally built.
The markings take the form of hieroglyphic symbols in red paint as well as lines in the stone that may have been made by masons when the chamber was being built.
According to Peter Der Manuelian, Philip J. King Professor of Egyptology at Harvard University, similar lines have been found elsewhere in Giza. “Sometimes they identify the work gang (who built the room), sometimes they give a date and sometimes they give guidelines to mark cuttings or directional symbols about the beginning or end of a block,” he said.
“The big question is the purpose of these tunnels,” he added. “There are architectural explanations, symbolic explanations, religious explanations — even ones relating to the alignment of the stars — but the final word on them is yet to be written. The challenge is that no human can fit inside these channels so the only way to do this exploration is with robots.”
