Abstract
Recent interpretive analysis of the astronomical calculator known as the Antikythera mechanism (AKM), the oldest geared instrument in the world, reveals that the astronomy it embodies is of the third to second century bc. The device has no known precursor and is more complicated than any surviving mechanism from the following millennium. Its apparent uniqueness stems from a failure to embed the device in the society, economy and technology of its time. After summarizing the circumstances of its recovery from a shipwreck in 1900–1901, subsequent excavations and the curation and analyses of associated materials through the 1950s, I turn to recent research. Studies of coins and ceramics from the wreck indicate that the freighter transporting the AKM foundered at some point between 70 and 50 bc. Meanwhile analyses of inscriptions on the device and other evidence link it to the Corinthian sphere of influence and suggest a date between 129 and 75 bc. Review of the literary and material history of astronomical devices and geared machinery of the period 100 bc–500 ad reveals relatives, but nothing comparable to the AKM in its range of functions. Yet it is not a Machina ex Deo. Archaeologists are encouraged to recover and analyze more evidence of the tradition it undoubtedly represents. Intensive research into the mode of production and the social, economic, technical and material aspects of the bronze and brass industries of the first millennia bc and ad is required.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
