In 1900, sponge divers discovered a Roman cargo shipwreck off the coast of Antikythera at a depth of 45 meters. The Hellenic Royal Navy launched the first expedition to retrieve the artifacts from the seabed. In 1901, fragments of what is known as the Antikythera Mechanism was retrieved. Since then, the Mechanism was under study by archaeologists and scientists in order to fully reconstruct it and understanding of its function.
This lecture will include the history of the discovery, early theories about the mechanism, and the latest fragments retrieved from the site.
