In the National Archaeological Museum in Athens you can find a special gallery for the finds from the Antikythera shipwreck, a boat carrying luxury goods from around 75–50 BC which was wrecked in a storm off the coast of Greece. It contained many statues, vessels, coins and of course, the famous 2000-year-old computer I’ve previously written about.
Many of the fine marble statues were recovered from the wreck site, but had been badly corroded after thousands of years lying on the seabed. The truly amazing finds however are those that were only half-buried in the seabed, leaving part of them beautifully reserved and part ravaged by time.
