Written in red paint, the symbols may help Egyptologists figure out why mysterious shafts were built into the pyramids.
•A robot was sent through the Great Pyramid of Giza and transmitted images showing hieroglyphs behind a mysterious door.
•Archaeologists hope the symbols might help them understand the purpose of shafts built within the pyramids.
•The Great Pyramid has long been rumored to have hidden passageways leading to secret chambers.
•A composite of images of the floor of the Great Pyramid is shown. Red hieroglyphs are visible
A robot explorer sent through the Great Pyramid of Giza has begun to unveil some of the secrets behind the 4,500-year-old pharaonic mausoleum as it transmitted the first images behind one of its mysterious doors.
The images revealed hieroglyphs written in red paint that have not been seen by human eyes since the construction of the pyramid. The pictures also unveiled new details about two puzzling copper pins embedded in one of the so called "secret doors."
Published in the Annales du Service Des Antiquities de l'Egypte (ASAE), the images of markings and graffiti could unlock the secrets of the monument's puzzling architecture.
"We believe that if these hieroglyphs could be deciphered they could help Egyptologists work out why these mysterious shafts were built," Rob Richardson, the engineer who designed the robot at the University of Leeds, said. The study was sponsored by Mehdi Tayoubi and Richard Breitner of project partners Dassault Systèmes in France
