Recent scholarship has greatly improved our understanding of the structure and function of the Antikythera mechanism.1 One unresolved issue is whether the mechanism included a display of the variability (or anomaly) in the angular motion of the Sun. In Price’s original reconstruction, the motion of the Sun was treated only in the mean. A single pointer indicated the day of the year in the Egyptian calendar and the position of the uniformly-moving mean Sun in the zodiac. Of course, the actual…

On the epoch of the Antikythera mechanism and its eclipse predictor
- Physics
- 2014
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.
