[edit]DescriptionNAMA Machine d'Anticythère 6.jpg |
English: Replica of the Antikythera Instrument: Based on the research of Professor Derek de Solla Price, in collaboration with the National Scientific Research Center "Demokritos" and physicist CH Karakalos who carried out the x-ray tomography of the original. This mechanism has been rebuilt to show the likely operation of the original. Price built a rectangular box of 33 cm X 17 cm X 10 cm with protective plates bearing Greek inscriptions of planets and operational information. The mechanism is a complex set of 32 gears of various sizes, turning at different speeds. The mechanism was offered by Prof. Price to the National Museum in 1980 and remains the reference for the study of the original despite the fact that its construction has been subject to much criticism. National archaeological museum, Athens, number BE 109/1980.
Français : Reconstruction de la machine d'Anticythère : elle est le résultat des recherches du Pr. Derek de Solla Price, en collaboration avec le Centre National de la Recherche Scientifique Démokritos et le physicien Ch. Karakalos qui a effectué les radiographies X et Gamma de l'original et du mécanisme reconstitué pour démontrer leur fonctionnement.
Price a construit une boîte rectangulaire de 0,33 x 0,17 x 0,10 m avec des plaques d'information et de protection, portant des inscriptions grecques sur les planètes. Le mécanisme est un ensemble complexe de 32 roues dentées de différentes tailles, tournant à des vitesses différentes. Le mécanisme a été offert par le Pr. Price au Musée national en 1980 et reste la référence pour l'étude de l'original, bien qu'il ait fait l'objet de critiques. Musée archéologique national, Athènes, n°BE 109/1980.
