The world’s oldest computer measures astronomical alignments

In 1900, the Antikythera mechanism was discovered in a shipwreck off the coast of the Greek island by that name. The device dates to around 150 to 100 BCE and calculates the positions of the sun, moon, planets and stars. There are hands for the zodiac as well, demonstrating its important in astronomy a century before the common era.

Below is a video showing the reproduction of this marvelous mechanism, including how it works.

As do many other archaeological artifacts, this divine device demonstrates just how advanced were some ancient cultures. I am very partial to the Greek culture, of course, having studied and spent quite some time in that lovely land.

It has been suggested that famed Greek inventor and genius Archimedes created this device, while others claim it was the astronomer Poseidonius of Rhodes who made it in 80 BCE.

Fascinating! It must have been a wonder to behold in antiquity!

  1. Perfectly Precise Device.
    When I look at that precise device, I have to wonder if intelligence evolves in the way that knowledge accumulates; that’s because that precise device makes me think that human intelligence then equaled the human intelligence of today. All that was missing then was the additional accidental discovery of ingredients which would have put planes in the sky in 100 BCE.

  2. God’s SunSon?
