This peculiar object created 5,000 years ago appears to be part of a component of an ancient unknown advanced mechanism.
In January 1936, a strange disk was unearthed at the plateau edge of North Saqqara, approximately 1.7 km north of Djoser's Step Pyramid in Egypt
The discovery of the mysterious prehistoric artifact, that many considered as a device, was made in the so-called Mastaba of Sabu (Tomb 3111, c. 3100-3000 BC) by a famous, British Egyptologist Walter Bryan Emery (1902-1971).
Sabu was the son of Pharaoh Aneddzhiba (fifth ruler of the first dynasty of ancient Egypt) and a high official or administrator of a town or province possibly called "Star of the family of Horus".
The burial chamber had no stairway and its superstructure was completely filled with sand and stone vessels, flint knives, arrows, few copper tools and the most interesting schist bowl in fragments.
