New mechanisms administered for the world's oldest computer

Archaeologists set out today to use a revolutionary new deep sea diving suit to explore the ancient shipwreck, where the Antikythera Mechanism was found.

The so-called Antikythera Mechanism, a 2nd-century BC device known as the world's oldest computer, was discovered by sponge divers in 1900 off Antikythera, a remote Greek island in the Aegean.

The highly complex mechanism of up to 40 bronze cogs and gears was used by the ancient Greeks to track the cycles of the solar system. It took another 1,500 years for an astrological clock of similar sophistication to be made in Europe.

Now archaeologists returning to the wreck will be able to use a new diving suit which will allow them to more than double the depth they can dive at, and stay safely at the bottom for longer.

Archaeologists believe many other artifacts are yet to be discovered in and around the wreck. Up to now they had only been able to operate at a depth of 60 meters.

Antikythera, which now has a population of only 44, was on one of antiquity's busiest trade routes, and a base for Cilician pirates, some of whom once captured and held the young Julius Caesar for ransom. He later had them all captured and crucified.

As well as the new Exosuit, the Antikythera expedition will also use robot mapping equipment and new advanced closed-circuit "rebreathers", which will allow divers much more time underwater.
