Robot discovers secret writing in Great Pyramid
The Great Pyramid of Cheops at Giza has always sparked the imagination. Among its many mysteries are four tiny passages running through the interior. The smallest are only eight inches square, far too small for a person to crawl through, so what were they for?
As you can see from the cutaway above, two of the tunnels angle up from the King's Chamber to exit the pyramid. Some researchers believe these have astronomical alignments. Like with all ancient agricultural societies, observing the heavens was important to the Egyptians. The other two tunnels seem not to go anywhere. Some claim they lead to hidden chambers, or allowed the pharaoh's soul to pass out of the tomb, but nobody really knows. Now a robot has added new pieces to the puzzle by going down one of these tunnels and filming it.
Robots in the pyramids are nothing new. Robotic exploration started in the 1990s, when remote-controlled cameras on wheels rolled up the two lower tunnels, only to find them blocked by strange stone "doors" decorated with a pair of copper pins. One of the doors had a small hole drilled in it, and a new robot with a camera on the end of a flexible cable looked on the other side.
What it found raises more questions than it answers. The secret door doesn't seem to have any way to open, and on the other side of it are hieroglyphs. Egyptologists are hoping the hidden message will explain one of the pyramid's greatest mysteries.
Why is there writing where nobody can read it? And why is the back of the door highly polished? There's also a mason's mark on the stone that the researchers are puzzling over. Egyptologists are busy trying to decipher the hieroglyphs and are planning more journeys for the intrepid robot. For more on the technology behind the discovery, check out this post on Dr. Zahi Hawass' website.
These are good times for pyramid studies. A satellite has detected what could be seventeen lost pyramids, and last summer the pyramids of Abusir and Dahshur opened to the public.
