I suppose that anyone interested in the history of science in the years BCE or archaeological oddities has heard of the Antikythera Mechanism. Found in a shipwreck off the coast of a Greek island, the box of gears and dials has been a puzzle and a marvel (a puzzling marvel?) for decades.
Marchant has dredged up the history of the device, from its collection off the Aegean seabed up through the first decade of the twenty-first century. Well, to be honest, the object itself hasn’t done much. It sat in storage in the National Museum of Athens for years before anyone decided to take a look at it. The museum – and the divers that worked on the wreck – were more interested in the statues and other objects of obvious value.
The Mechanism turned out to be a specialized device for computing the many lunar cycles – and possibly some dials that compute planetary positions as well (parts are still missing). Marchant doesn’t spend much time on the astronomy or mathematics behind it; she’s far more interested in the archaeology and personalities in its story.
