— The Antikythera mechanism is the most technologically sophisticated artifact that survives from antiquity. Currently dated to 150—100 B.C.E., it has also been described as the world’s oldest known analog computer. A shoebox-sized assemblage of 37 interlocking gears and dials, the Antikythera mechanism is an astronomical calculator complex and precise enough to predict eclipses and track the positions of the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn down to the hour, even compensating for their elliptical orbits—contradicting the prevailing Greek philosophical belief of its time that all orbits were perfect circles.

Discovered in a Roman shipwreck by sponge divers in 1901 off the southern Greek island of Antikythera, the first scholars to observe the device considered it an anachronism—an object that challenged conventional historical chronology, too complex to have been constructed during the same time period as the bronze statues and other objects discovered along side it. Devices with the level of complexity of the Antikythera mechanism would not appear again until the 12th century.(*)

Today some researchers believe that though Greek, the Antikythera mechanism actually embodies Babylonian not ancient Greek astronomy, pushing its origins even further into antiquity as well as geographically eastward. Finally, though thought to be rare if not unique, many researchers say that its refined design and manufacturing suggests that it had a number of undiscovered predecessors and perhaps was even the product of an as-of-yet unknown guild.

This is a photo of me taken through a double-axis diffraction grating film off the coast of Kythera, the island just north of Antikythera. It documents here more of a ‘parachronism’, something along side of or adjacent to something else in time and place.

(*) The notion that the Antikythera mechanism is anachronistic (from the Greek ana: against and chronos: time), reveals more our expectations and ignorance of history rather than anything about the actual material circumstances of the device. Declaring artifacts anachronistic springs from, as well as reinforces, the commonsense perspective of history as a uniform and continual unfolding of a primitive past into our uniquely technologically advanced present.
