I just happened to see the thing recently,
when I visited Athens in the end of May.
The mechanism is really very impressive,
(I have seen nothing else before with toothwheels,
manufactured before I-st century AD. It looks
like a modern clock or an analog computer indeed.)
The mechanism is badly damaged though, so it is
really hard to understand what its function was.
A very fine collection of surgical instruments
is displayed next to it (salvaged from the same
ship). Apparently this was a ship of an antique dealer:-)
because it carried many ancient statues
(I mean much more ancient than the ship itself).
They say the ship sank in the year 80 AD.
About 1/3 of the exponats of
the Archeological Museum in Athens comes from
this ship.
The Antikythera mechanism and surgical instruments
seem to provise another strong argument to the opinion
that science was much more developed in the Ellinistic
states then it is commonly acknowledged.
