The Antikythera Mechanism,  R D Wright Lecture by Professor John Seiradakis, Department of Physics, Aristotle University of Thessaloniki, Greece as presented at the University of Melbourne.

The Antikythera Mechanism was a portable (laptop-size), geared mechanism, built ca. 150–100 BCE, which calculated and displayed, with high precision, the movement of the sun and the moon and the phase of the moon for a given epoch.
