Antikythera Mechanism computer-generated Source: Wikipedia |
Anonymity has disappeared. Thanks to developments in the
second half of the twentieth century and the beginning of the twenty-first
century, we are now in the age of nanotechnology. Computers have changed in
size from an entire building to the size of a credit card and even smaller.
I was very surprised to find out that we had an analog
computer in 87 B.C. made of bronze. Captain Demetrios Condos sent his bored
crew around the Antikythera Island to dive for sponges shortly before Easter
1900. His boat had been driven off course an entire week by gale winds off the
Island of Crete into the calmer waters of the northern tip of Antikythera
Island, Greece.
The most exceptional seaman, Elias Stadiatis, dove to 140
feet, aided by lead weights attached to his diving boots. He yanked the rope to
be pulled up and, instead of bringing up sponges, he told Captain Condos about “naked
women and horses” he saw on the bottom. The next dive revealed a shipwreck dating back
to 80 B.C. Treasures and statues were scattered and plainly visible on the sea
floor. The shipwreck find was so exciting! The happy sailors were imagining a
treasure trove of gold coins and jewels.
When the salvage operation finally commenced in November
1900, the difficult and dangerous work lasted nine months. Dangerous weather
conditions and primitive techniques made scuba-diving so precarious and
perilous that one deep-sea diver died and two were seriously hurt.
Among the treasure trove found in the Mediterranean and later
housed at the National Archeological Museum in Athens, an archeologist named
Valerios Stais discovered one single encrusted bronze mechanism in a pile of discarded debris and marble
pieces. It appeared to be a clock of sorts.
Fractured later into three pieces, the mechanism lost
smaller pieces later during handling and cleaning. Since the initial find, 82
fragments have been discovered by subsequent expeditions, including that of
Jacques Cousteau. Seven fragments are actually significant because they contain
the mechanism’s gears and inscriptions in Koine Greek.
Valerios Stais announced in 1902 that his find, half the
size of a portable typewriter at that time, was an ancient Greek astronomical
device. Some thought it was an astrolabe, a tool used by navigators to measure
angles of distances between planets and stars above the horizon. Others thought
it was a planetarium. Some believed the
mechanism was too complex to be either one and must have been “created by
aliens from outer space.”
Professor Derek de Dolla Price of Yale concluded that it was
a computer made in 87 B.C. comprised of 30 bronze gears to calculate the
movement of the Sun, Moon, and planets. Professor Price described the discovery
as “finding a jet plane in King Tutankhamun’s tomb!”
The Antikythera Mechanism, also called the Rhodes calculator,
“the forerunner of the computer age” was described as the “wheeled computer of
the heavens.” It mathematically calculated the movements of planets and
celestial bodies during a period of time when humanity believed that the Earth
was a disc floating on a great ocean with the sky above like a bowl. “The
planets and the Moon were thought to move along certain geometrical paths.” The
mechanism was to calculate and determine the celestial bodies’ exact movement,
making further calculations unnecessary.
In 1976 Jacques Cousteau and his crew found coins at the
wreck site dating between 76-67 B.C. Cousteau’s coins may point the origin of
the mechanism to the city of Pergamon.
Because the mechanism was so complex, The Antikythera
Mechanism Research Project concluded in the late 2000s that it was probably
made in the Corinth colonies of ancient Greece such as Syracuse.
The Rhodian style vases may point to the city of Rhodes.
Rhodes was a center of astronomy and mechanical engineering and home to
Hipparchus with his theory of the motion of the Moon.
Michael Edmonds of Cardiff University described the
mechanism in 2006 as “more valuable than the Mona Lisa” because the astronomy
was correct.
Carman and Evans, in their 2014 study dated the mechanism to
200 B.C. and attributed it to the Babylonians. If that is so, why is the
inscription in Koine Greek?
A new expedition is planned for spring 2015 by the
Hellenistic Ministry of Culture and Sports. They are hoping to find new parts
of the Antikythera Mechanism.
