Sabu Disc.In 1933, during excavations in the Egyptian village of Saqqara, 30 kilometers from Cairo, British archaeologist Walter Emery discovered something strange. While investigating Sabu's tomb, the scientist found a stone disc with three petal segments surrounded by a thin rim.
Sabu was a high-ranking official who lived during the reign of the first dynasty of pharaohs (3000-2800s BC). Over the past 80 years, Egyptologists still do not agree on why he needed such an unusual, unparalleled object. Some argued that it was a part of the lamp, although the lamps of this shape have never been seen before, someone was sure that it is a plate, but it is difficult to use it for eating.
The wheel had not yet been invented by the Egyptians in those years, nor could it be a protopropeller or a prototype of a propeller. Perhaps the Sabu disk had no utilitarian application at all, being some kind of sacred object, albeit unknown until now.
