Ancient Greek science

The Antikythera mechanism, an ancient Greek hand-powered orrery, which is the oldest known analog computer, followed the Greek lunar calendar, not the solar one used by the Egyptians as previously believed, according to new research by a team from the University of Glasgow.

Archaeologists investigating the wreck of a Roman cargo ship off the coast of Antikythera, southeast of the Peloponnese, made several interesting finds during May-June underwater excavations that had not been expected to yield much excitement, but to be of a more technical nature.

In the fifth installment of this beloved swashbuckling series of films, Indiana Jones (Harrison Ford) races against time to retrieve a legendary dial, the Antikythera Mechanism, created by ancient Greek scientist Archimedes in the 3rd century BC that can change the course of history.

Wednesday's Google Doodle celebrates the 115th anniversary of the discovery of the Antikythera Mechanism, one of the most remarkable scientific objects of antiquity.

The 2nd-century BC device, often hailed as the world's oldest computer, was retrieved from a shipwreck by sponge divers in 1902 off the remote Aegean island.

To complement its ongoing "Voyage" exhibition, the Herakleidon Art Museum is launching a show on the Antikythera Mechanism.
