On the pin-and-slot device of the Antikythera Mechanism, with a new application to the superior planets

Perhaps the most striking and surprising feature of the Antikythera mechanism uncovered by
recent research is the pin-and-slot device for producing the lunar inequality. 1 This clever
device, completely unattested in the ancient astronomical literature, produces a back-and-
forth oscillation that is superimposed on a steady progress in longitude—nonuniform circular
motion. 2 Remarkably, the resulting motion is equivalent in angle (but not in spatial motion in
depth) to the standard deferent-plus-epicycle lunar theory. Freeth et al. gave a proof of this …
