An Ancient Computer Built in 100 B.C.

The Antikythera Mechanism: This wonder was build in around 100-150 BC. We cant imagine how those ancient people without any advanced technology built this computer.

What is the Antikythera Mechanism

The Antikythera Mechanism is a very or ancient mechanical computer that is designed to show astronomical positions, like the position of the sun, moon and different planets in our solar system during different time. It was found in 1901 by some sponge divers in a shipwreck off the Greek island of Antikythera. Unfortunately the part that was found was only a part of the mechanism and it contained a mass of corroded metal, thin flat round bronze plates and gears with triangular teeth. After some investigation scientists concluded that it was made in around 150-100BC. And scientists also guess that it was on a ship that sank in the route from the Greek island of Rhodes to Rome. This mechanism was a very improved technological artifact at that time. And this type of mechanism was not made until thousands of years after the Antikythera mechanism was made.


The Antikythera Mechanism is the oldest known complex scientific device. This mechanism contains many gears and is regarded essentially as an analog computer. Scientists state that this mechanism was build upon the theories of astronomy that the Greek scientists developed. And all the instructions of the mechanism are written in Greek. So, scientists guess that it was probably made in Greece. But why was it in a cargo ship? We are still not sure, but it was most probably that this mechanism was being transported to Rome from Greece, along with other loots.

Even though we know that where the mechanism was made in, we still are not sure who or where it was made. One hypothesis is, it was made in an academy which was founded by the ancient philosopher Posidonius, which is located in the Greek island of Rhodes. And it was designed by the astronomer Hipparchus because the mechanism has a lunar mechanism that uses the Hipparchus’s theory for the motion of the moon. But some recent researches also states that the concept for the mechanism originated in the colonies of Corinth, which has a connection with the famous astronomer Archimedes.
