The world's oldest mechanical computer: the Antikythera mechanism
Discovery:
31 The Antikythera mechanism was discovered as part of a ship's in the sea near Antikythera, Greece.
Initially, it was mistakenly thought to be a piece of 32 , but it was later found to be a mechanism that had broken into pieces.
Equipment used for analysis of the mechanism:
For its analysis, various equipment was used: the "Dome" produced photographs that made the 33 clearer, and the "Blade-Runner" produced X-rays, originally used to identify 34 in engines.
Description:
The mechanism consisted of over 30 gear wheels made of 35 , models of the sun, moon, and planets, and a framework made of 36 .
How the mechanism was used:
The operator turned a 37 to move the gear wheels, allowing the sun, moon, and planets to be positioned correctly for any given date.
Most surprisingly, the mechanism could calculate when an 38 would occur and may have been used as a 39 for planning festivals.
Later use of similar technology:
Later, similar technology was used in the 13th and 14th centuries for making 40 in Western Europe.
