The Antikythera mechanism’s astronomical reconstruction

Record summary

The Antikythera mechanism, recovered from a shipwreck in 1901, was reexamined through epigraphy, radiography, surface imaging and mechanical reconstruction during this period. Studies identified a geared device for calendrical and astronomical calculations, transforming an apparent technological anomaly into evidence for Hellenistic instrument-making traditions. Questions remained about its workshop, precise date, original completeness and relation to lost technological literature. The lead is useful for comparing spectacular claims of impossible ancient technology with incremental evidence from inscriptions, gears and historical context.
