In 1936, Egyptologist Walter Bryan Emeral, during excavations Mastaba Sabu (Tomb 3111, c. 3100-3000 BC) at Saqqara, was discovered disk is divided into three parts. Sabu was the son of Pharaoh Aneddzhiba (fifth ruler of the first dynasty of ancient Egypt).
This mysterious disc was found among pottery, bones and several other stone objects that Sabu, wanted to take to the afterlife.
The device is approximately 5.23 inches in diameter and a little more than 4 inches high. Although initially thought that it was carved out of slate, it turned out the disc is made of stone metasilta — a material commonly used by Egyptian carvers for its ability to withstand the small, detailed work without fracture. Other vessels found in the tomb, also carved out of the dense stone.
How wide flat bowl with three thin, raised petals, object shape, which resembles a propeller with three blades and a hole center, suggests that it was mounted on the axle. Even for metasilt-stone detail disk (especially the three petals and the center of the cylinder) is incredibly thin. While the drive is not in compliance with perfect symmetry, all its petals are approximately the same size and are oriented at 120 degrees from the center. But regarding the actual function object, researchers still are not sure.
At the time, while they may not be able to determine what it was, many agree that the exhibit was not the wheel, since the wheel appeared only in Egypt 1500 BC, during the 18th Dynasty, with the Hyksos invasion. However, some prints, from the place where the painted wheels, returning to the fifth dynasty, about a thousand years before that period. Sabu disc, however, an even greater challenge to Egyptologists because it dates knowledge of the wheel to about 3000 BC during the time of the first dynasty.
Another even more incredible version suggests that this stone disc served as a kind of hydraulic propeller with fins, that would imply that the Egyptians already had the technology to build the electric motors. Since the stone can not be the material for such a device, known Egyptologist Cyril Aldred, considering how easy drive up the metal object, much older than that.
Of course, some believe that this subject served another purpose, just to be able to drive foot oil lamp. However, critics of this theory argue that the three-blade ceremonial lamp hardly possible, because of the shape and curvature of its petals, which seems to suggest a function, not just decoration.
So why such a complex shape? Unless it was a prop vehicle, then the disc is strange to be part of a component of an ancient mechanism — perhaps as a way to process grains or fruits. Some have even suggested that it was part of a generator or battery to produce electricity.
Skills required for the manufacture of such objects is also important. If someone wants to make such a facility today, it would require something like a modern three-dimensional computerized milling machine. Because the technology is to form so thin proportional forms of solid stone.
So this exhibit shows a significant residue (or reproduction) of ancient technology, or — it's just a decorative copy showing kamnerezchika qualified talent?
In any case, divided into three parts drive is now located on the first floor of the Cairo Museum, where all can appreciate the exhibit and wonder what technology the Egyptians were able to create their stories.
