According to recent research the Antikythera Mechanism dated around 100 to 150 BC , it is an astronomical clock – an advanced tool of its time. Its use is mainly calendar and astronomical. With this tool, the ancient Greeks could calculate:

  1. the dates when the Sun changed its annual month course on the ecliptic
  2. Changes of Zodiac Signs

  3. Phases of the Moon

  4. Moon and Sun eclipses on the principle of repetition after 18 years and 11 days (Saros).

  5. Establish the dates and years of the Olympic Games, the Pythian Games, the Isthmian and Nemean games.

It is also possible that the mechanism included the movements of the planets Mars and Venus, which is not confirmed by the evidence so far.Based on the above, the use of this mechanism of Claudius Ptolemy, the Vetious Valence and other Greek astrologers, is probable. From these data, however, that the astrological use of the mechanism is feasible since making accurate:

  1. The Sun’s ingress into new Zodiac and the exact angle (position) of the ecliptic.
  2. determine the phase of the Moon
  3. predicting eclipses
  4. Additionally facilitates determining the position of planets in the zodiacal constellations.

In the event that demonstrated by scientific research that the mechanism included the description of several planets would make the Antikythera Mechanism Astrological invaluable tool. It should be emphasized that the Geocentric theory is not enough to build a mechanism for calculating the orbits of the planets in the zodiac. Known as the solar system is heliocentric with the planets in elliptical orbits around the Sun, with the Sun at one of the two foci of the ellipse. All data but contribute to the acceptance of the geocentric theory of the era built this mechanism.


Aristarchus of Samos (310 to 230 BC) is the first scientist who introduced the heliocentric theory of the Earth being the third largest planet orbiting the Sun in a circular orbit. For various reasons that are not present, the heliocentric theory prevailed in ancient Greece to the “discovered” again Copernicus after about 1700 years. If prevailed theory of Aristarchus, the mechanism could describe the orbits of the planets in a relatively simple manner by relying on this theory.

Claudius Ptolemy (about 90 to 178 AD) was a great astronomer, mathematician and astrologer of the Hellenistic period. The theory of epicycles attempts to describe the movements of the planets on the celestial dome. The theory is described in detail in his book “Mathematical great retirement.” Because the calculation of the orbits of the planets under the geocentric theory was weak, Ptolemy devised the system of epicycles by which planets do orbit around a point which is in orbit around the Earth. With this system could not be finally solved the riddle of the motion of planets simply because they were on the wrong footing after the planets about the Sun and not the Earth. It is quite possible that this great astronomer had to build a mechanism similar to the Antikythera more complex form since it would incorporate gears for the implementation of the theory of epicycles. Finding such a mechanism by archaeological research would be desirable. Summarizing believe that the Antikythera mechanism could be used as a tool Astrological alongside the Astronomical use as a diary. The description of the mechanism of the motion of planets, regarded as probable by some scientists, will be a great surprise since the theoretical background of the era of the second century BC was not sufficient for an illustration of these movements. Since Claudius Ptolemy lived 250 years after the construction of the mechanism, it is quite possible to construct a mechanism was similar quality to describe the motion of planets 5 key according to the theory of epicycles.

In each case the mechanism shows the high technological evolution of Ancient Greek Culture makes clear that philosophy, the theater, the Republic, the Olympic Games, the history, the art of war and many areas and ideas found their birth and climax in Ancient Greece along with high technology machines and computers of the era.

If you however come in Greece till this spring you will have a wonderful chance to meet the Antikythera Mechanism for the first time in the National Museum of Athens till the end of April of 2013.http://www.namuseum.gr/index-en.html
