 | The Antikythera mechanism is an ancient Greek hand-powered orrery, the first analogue computer and the oldest known example of such a device. |  |
 | The artifact was retrieved from a shipwreck in 1901. It is dated to about 100 BC and represents lost technology. A complex clockwork mechanism composed of at least 30 meshing bronze gears was designed to convey our place in the universe and forecast celestial events like lunar and solar eclipses. |
