Âronze fragments from the Antikythera mechanism. 1st cent. B.C.
Bronze fragment from a complex, mechanical tool with bronze gears housed inside a wooden case covered with inscriptions. Made by a genius in mathematics, astronomy and mechanics in the 1st cent. B.C., it remained unparalleled for at least a millennium afterwards.
According to the conclusions of the Antikythera Mechanism Research Project, the device faithfully reproduces the moon’s motion across the sky and its phases during a month, forecasts eclipses, counts time and operates as a multi-faceted calendar based on circular or spiral scales. It should have been a useful tool for astronomic observations and teaching. Furthermore, it should have eased mapping and navigation, since it counts latitude (and possibly longitude).
