There is a black-and-white ball over the front dial of the Antikythera device. This ball seems to be inlaid into a bronze disk. The device, including the disk and the ball, has been regarded as the moon phase display device. The detailed design regarding how to operate this device by the output motions of the interior mechanism is a quest, due to the damage surviving evidence. The purpose of this chapter is to analyze all feasible designs of the moon phase display device.
