Secrets of the Antikythera Mechanism: 1 & 2

Approximately three hours of lectures on the Antikythera Mechanism. This is of great interest to Hellenistic astrologers, as well as astronomers, historians, and others. The mechanism even calculates Saros cycles, phases of the Moon, planetary motions and much more. The third video shows a Virtual Reconstruction of the Antikythera Mechanism (by M. Wright & M. Vicentini)
