Antikythera Mechanism

and wooden grandfather CLOCK

The Antikythera Mechanism is a 2200 year Ancient Greek portable planetarium

and is the first known analog computer. The front dial displays the

zodiac position of the first 5 planets, sun, moon phase and date.

The 57 gears computes addition, subtraction, multiplication, division and

7 harmonic orbit first order Fourier Transforms!

The back dials display the 72 year lunar calendar, Olympic games calendar

and most important predicts a solar or lunar ecliplse.

The mechanism was housed in a wooden box complete with a built in instruction manual.

The mechanism is not operated vertically as illustrated in the videos below.

The mechanism is operated horizontally to minimise gear backlash.
