Calendars with Olympiad display and eclipse prediction on the Antikythera Mechanism
@article{Freeth2008CalendarsWO, title={Calendars with Olympiad display and eclipse prediction on the Antikythera Mechanism}, author={Tony Freeth and Alexander Jones and J. Michael Steele and Yanis Bitsakis}, journal={Nature}, year={2008}, volume={454}, pages={614-617} }
Previous research on the Antikythera Mechanism established a highly complex ancient Greek geared mechanism with front and back output dials. The upper back dial is a 19-year calendar, based on the Metonic cycle, arranged as a five-turn spiral. The lower back dial is a Saros eclipse-prediction dial, arranged as a four-turn spiral of 223 lunar months, with glyphs indicating eclipse predictions. Here we add surprising findings concerning these back dials. Though no month names on the Metonic…

The deeply puzzling grouping and ordering of these Index Letter Groups was solved with a simple mathematical model, which both explained these groups and the distribution of the glyphs round the Saros Dial—revealing an eclipse prediction scheme of extraordinary sophistication and ambition.

On the epoch of the Antikythera mechanism and its eclipse predictor
- Physics

A series of constraints are applied, in a sort of sieve of Eratosthenes, to sequentially eliminate possibilities for the epoch date of the Antikythera mechanism, finding that the solar eclipse of month 13 of the Saros dial almost certainly belongs to solar Saros series 44.

The latest decoding of the Antikythera Mechanism casts fresh light on the way these calendar schemes were planned, used and integrated, and shows it to be an instrument of unparalleled sophistication in antiquity.
