A new search has begun at a Greek island where an ancient device known as the world's "oldest computer" was found over a century ago, an official said Thursday, adding that other discoveries were possible.

 this week returned to Antikythera, the Aegean Sea island where sponge divers in 1900-1901 found the so-called Antikythera Mechanism, a remarkable 2nd-century BCE device that tracked the cycles of the solar system.

"These are unexplored sea depths beneath a trade route known since antiquity," said Angeliki Simosi, head of Greece's ephorate of underwater antiquities.
"This is virgin territory," she told AFP.

Believed to operate by crank and containing inter-meshing gears, the mechanism could be used to calculate eclipses and moon cycles. The technology was comparable to astronomical clocks that only appeared some 1,600 years later.
It was found in the wreck of a  apparently carrying booty to Rome.
The Greek team is assisted by Brendan Foley, a marine archaeologist from the Woods Hole Oceanographic Institution at Massachusetts, who has helped in past outings to identify ancient shipwrecks over the last five years.

A reconstruction of Antikythera Mechanism is displayed at an exhibition of ancient Greek technology in Athens in 2005. A new search has begun at a Greek island where the ancient device known as the world's "oldest computer" was found over a century ago, an official said Thursday, adding that other discoveries were possible.

Foley is contributing  to map the  and rebreather equipment that partially recycles a diver's oxygen and will enable the researchers to probe previously inaccessible depths, the senior archaeologist said.

Simosi said she had visited Antikythera in 1985 during construction work to widen the local port of Potamos and the bay was "full of antiquities".
"I believe we could find something equivalent to the ," Simosi said.

"If we do, the entire department will likely need to be sent out," she said.
The operation, jointly funded by the Greek state and Woods Hole, will continue until October 22.
