Thirty meshed bronze gears in a wooden case the size of a shoebox, hauled from the sea floor by sponge divers. The classical world built a computer — and then, for fourteen centuries, forgot how.

CLEARANCE OPENFile Notes // Observations
The mechanism survives as eighty-two corroded fragments, but the fragments confess everything. X-ray tomography counts at least thirty meshed bronze gears, cut by hand to tolerances a Swiss watchmaker would respect. A crank on the side advanced pointers across a front dial marking the zodiac and the Egyptian calendar; turn it, and the sun and moon crossed the sky in miniature, the moon’s pointer even slowing and quickening to model its elliptical orbit — an anomaly the Greeks could describe but supposedly could not machine.
The rear face is stranger still. A spiral dial tracks the 223-month Saros cycle, predicting eclipses years in advance — glyph by glyph, with notations for the hour and the color the sky would turn. Another subsidiary dial counts down the four-year circuit of the Olympiad. This is not an ornament or a votive object. It is an instrument built to be consulted, by someone who expected the heavens to keep its appointments.
No comparable gearwork appears anywhere in the surviving record for another fourteen hundred years. Either the record is wrong, or the lineage was cut.
That silence is the true anomaly under study. Devices of this order are not built once; they imply workshops, teachers, failed prototypes, rival commissions — an entire engineering tradition of which the mechanism is the sole surviving witness. The Imperium’s working conclusion is uncomfortable and simple: civilizations can run ahead of their own history, and what an age can build is not always what an age remembers. The archive exists for exactly such orphaned lineages.
Custody // Provenance Chain
Fabricated
Cut and assembled in a Greek workshop — Rhodes or Corinth remain the leading attributions.
Lost at Sea
A Roman-era cargo vessel founders off Antikythera; the mechanism sinks with a hold of bronzes and glassware.
Recovered by Sponge Divers
Divers from Symi raise the wreck’s cargo; a corroded lump of bronze and wood is set aside, unrecognized.
Tomography Deciphers the Inscriptions
X-ray tomography reads thousands of hidden characters — the device’s own user manual, engraved inside it.
Cross-Reference // Adjacent Files
Another feat of precision the record cannot fully explain — geometry raised against the horizon.
The treatises that could have named the mechanism’s makers may have burned in these stacks.
Another artifact out of sequence — this one arriving from the far side of the timeline.
