Antikythera Mechanism

Record summary

The Antikythera Mechanism is a corroded geared device recovered from a Roman-period shipwreck and usually dated to the late Hellenistic period. Its inscriptions and reconstructed gear trains indicate sophisticated astronomical calendrical functions, including cycles associated with the Moon and eclipses. It matters for comparing ancient technological knowledge, craft specialization and the transmission of Greek scientific ideas. Uncertainties remain about its original design, missing components, workshop context and the precise interpretation of some inscriptions and dials; reconstructions are partly inferential rather than direct observations.
