Archaeologists revisit rich Roman wreck off Greece

Archaeologists armed with top-notch technology have scoured one of the richest shipwrecks of antiquity for overlooked treasures, recovering a scattering of artefacts.

Lying 164 feet down a steep underwater slope off Antikythera Island, in southern Greece, the Roman commercial vessel’s wreck was accidentally located by sponge divers more than a century ago.

Assisted by the Greek navy, they raised, among other things, the so-called Antikythera Mechanism, a complex clockwork computer that tracked the cycles of the Solar system and could predict eclipses to a precise hour on a specific day.
