The Antikythera Mechanism
Unknown
2nd half of the 2nd century BC · bronze
Ancient Greek (Hellenistic) · Hellenistic Greece
A corroded bronze geared instrument recovered from the Antikythera shipwreck, built from at least 30 gearwheels along with dials, scales and pointers. It is widely regarded as the earliest surviving portable astronomical calculator, used to track the sun and moon (and probably the five planets known in antiquity), predict eclipses, and display the dates of the Panhellenic games.
“Seven large fragments (Α-G) and 75 minor pieces (1-75) have survived. Their exact position and the original structure of the Mechanism are still a matter of intense investigation. It contained at least 30 gearwheels as well as dials, scales, axles and pointers. The greek, astronomical inscriptions on the surface of the Mechanism refer to astronomical and calendar calculations, while the inscriptions on its metal protective plates contain instructions for its use. The Mechanism was protected by a wooden case, which had a bronze plaque on the front and another one at the back side. The Antikythera Mechanism is the earliest preserved portable astronomical calculator. It displayed the positions of the Sun, the Moon and most probably the five planets known in antiquity, Mercury, Venus, Mars, Jupiter and Saturn. It was used to predict solar and lunar eclipses, it kept an accurate calendar of many years and displayed the date of the Panhellenic games held at Olympia, Delphi, Nemea, Isthmia and Dodona.”
