In episode 440 astrologers Chris Brennan and Sam Ogden discuss the Antikythera Mechanism, which is a complex mechanical device that was recovered from an ancient shipwreck, and how it may have been used for astrology.
The Antikythera Mechanism was discovered in the year 1901 by a group of sponge divers who found an ancient shipwreck near a Greek island named Antikythera.
They had found a Greek merchant ship that sank around the year 60 BCE, and divers were able to recover a number of ancient statues, pottery, as well as a corroded mechanical device with lots of gears.
Over the past century a series of researchers have slowly reconstructed the device, and recently advanced X-ray scans have allowed scholars to look inside to see how it worked.
We now know that it was a complex astronomical device that depicted the movements of the cosmos, and it was also a sort of mechanical calculator or computer that could compute positions of the planets in the past or future, predict when eclipses would occur, and more.
The discovery of the Antikythera Mechanism is important because it is far more advanced than what was previously thought possible in terms of technology around the 1st century BCE, and similar devices were not reinvented in Europe until after 13th century.
For our purposes as astrologers the most interesting piece is how the Antikythera Mechanism ties in with the history of ancient astrology, and that there is in fact some evidence the device was used for astrological purposes, as well as that there was at least one astrologer who is said to have owned a similar device.
In this episode we situate the device within the context of the history of astrology, talk about its possible astrological uses, and also discuss how the mechanism may helps us to reconstruct the origins of Hellenistic astrology as a result of the planetary order depicted on the device.
