Antikythera mechanism
WIKIPEDIA
The Antikythera mechanism (pron.:
/ˌæntɨkɨˈθɪərə/
ANT-i-ki-THEER-ə
or /ˌæntɨˈkɪθərə/
ANT-i-KITH-ə-rə)
is an ancient analog
computer[1][2]
designed to calculate astronomical
positions. It was recovered in 1900–1901 from the Antikythera
wreck,[3]
but its significance and complexity were not understood until a
century later. Jacques
Cousteau visited the wreck in 1978[4]
but, although he found new dating evidence, he did not find any
additional remains of the Antikythera mechanism. The construction has
been dated to the early 1st century BC. Technological artifacts
approaching its complexity and workmanship did not appear again until
the 14th century AD, when mechanical astronomical
clocks began to be built in Western Europe.[5]
The Antikythera mechanism is displayed at
the National
Archaeological Museum of Athens, accompanied by a reconstruction
made and donated to the museum by Derek
de Solla Price
All of the mechanism's instructions are written in Koine
Greek,[7][not
in citation given] and the consensus among scholars is that
the mechanism was made in the Greek-speaking world. One hypothesis is
that the device was constructed at an academy founded by the Stoic
philosopher Posidonius
on the Greek island of Rhodes,
which at the time was known as a center of astronomy and mechanical
engineering; this hypothesis further suggests that the mechanism may
have been designed by the astronomer Hipparchus,
since it contains a lunar mechanism which uses Hipparchus's theory
for the motion of the Moon. However, recent findings of The
Antikythera Mechanism Research Project suggest that the concept
for the mechanism originated in the colonies of Corinth,
which might imply a connection with
Archimedes.
