The Antikythera mechanism is one of the most astonishing discoveries in archaeology. Salvaged from a 2,000-year-old shipwreck in Greece in 1900, the intricately geared contraption was quickly recognized as a machine for calculating the movement of the moon and planets. It continues to surprise, as researcher Tony Freeth reveals on page 24. The gears are more delicate and complex than we knew when Freeth shared his team’s results in 2009, predicting more celestial events with precision and ingenuity. This isn’t the first issue of Scientific American to share the Antikythera device on the cover; it was our lead story in June 1959 as well. That edition, available in our digital archives, is bursting with ads for new plastics—Marlex from the Phillips Chemical Company, Delrin from DuPont—asbestos fiber from Johns-Manville, rocket navigators from Northrop, and the “first all transistorized analog computer” for $4,000 from Electronic Associates, Inc. Many of these products are long forgotten, but the Antikythera
(pronounced with stress on the syllable “kyth,” like “pith”) mechanism and research on it will probably outlast them all.
