In a paper presented a year ago, "Understanding the Antikythera Mechanism," Wright faulted some of Price's conclusions. Wright speculated that the Mechanism could be an elaborate planetarium, designed to show the movements of the five then-known planets in addition to the sun and moon, and to predict eclipses. He also suggested that the Mechanism was actually a marriage of at least two separate devices, one being added to the device already in the wooden case. He demonstrated that Price's differential gear was actually an epicyclical gear, in which a central wheel meshes with one or more peripheral gears, which rotate around the center.
