The computer is the epitome of the modern age. It is hard to believe, then, that more than 2,000 years ago, the Ancient Greeks had already developed their own mechanical computers.

From the classical world of the third century BC come three of the most important inventions in history: the clock of Ctesibius, the odometer designed by Vitruvius, and the incredible Antikythera Mechanism, which scientists are still trying to explain.

Each of these mechanisms has had a profound effect on the development of technology down through the ages. And they were not chance inventions! Some of the greatest minds of Ancient Greece made major contributions to science as we know it today.

Follow this amazing story of ancient machines and their creators.
