The Antikythera shipwreck — source of the famous ancient clockwork Antikythera Mechanism — has remained shockingly unexplored in the 100 years or so that we've known about it. In fact, other than a visit by Jacques Cousteau in 1970s, there hadn't been any official, scientific excavations until last year. Turns out, there's a lot of stuff left to find at the site
, from a ship's anchor and storage jars to a collection of bronze fragments — which could either turn out to be something mundane, like nails from the boat, or more clues to the Mechanism. According to The Guardian's Jo Marchant, "little bronze fragments" describes what the gears of the Antikythera Mechanism looked like before they were detached from rock and cleaned of rust.
