One particular part ofthe cargo has attracted the interestsof historians of science:the remains of a technicalinstrument, which were recognized soon after discovery. (The detailsofthe recognition in 1902, attributed to Spyridon Staïs,the Minister of Education in the Greek government, aregiven in the book underreview [38–41]; see Kaltsas, Vlachogianni, and Bouyia2012, 18–31 and 228 for a description ofthe discovery of all the fnds in 1901–1902 and for the recognition of the instrument.) In 1972, X-rays were taken ofthe Mechanism byradiographer Charalam- bos Karakalos forthe physicist Derek de SollaPrice.These showed that it originally comprised over 30 interlocking, toothed gears and several plates that were interrelated bytheir capacity to mark time in various ways: an Egyptian calendar; a zodiac-dial; and a star-calendar(parapegma).
