The first protractor in the world

An Italian scientist claims that a strange object found in a tomb belonging to an ancient Egyptian architect is actually a protractor, probably the first one ever created by man. The tomb belonged to Kha, an architect who is believed to have built the tombs of the Pharaohs of the 18th dynasty, around 1400 BC. His tomb was discovered in 1906, where they found various tools, among them a wooden object resembling a sort of ruler, however no one can be sure. 



Amelia Sparavina, a physicist at the Polytechnic in Turin claims that the numbers and symbols found in the elaborate carvings of the instrument show that this is a protractor. She even believes that this is a complex protractor which could make measurements at two levels, one based on the mathematical system (followed by the ancient Egyptians) and one based on the corporal, i.e. the 36 constellations of the Egyptian astrology, which became the basis for the creation of the famous Egyptian stellar clock.
