In 1901 sponge divers hauled a lump of corroded bronze from a Roman-era wreck. It turned out to be a hand-cranked analog computer that modeled the heavens — and nothing else like it appears in the record for another 1,000 years.
BBC Reel's tight primer on why archaeologists refused to believe what they were looking at. Start here to grasp the scale of the anachronism.
82 surviving fragments, at least 30 bronze gearwheels, and inscriptions acting as a user's manual. The definitive rundown of a device we've spent a century decoding.
World of Antiquity strips away the 'ancient aliens' hype and asks what the mechanism actually proves about Greek engineering and lost knowledge.
Machinist Clickspring recreates the mechanism using only tools available in antiquity — and in the process discovers new things about how the original was made.
The Stanford talk from the researcher who spent decades reverse-engineering the gearing. Watch the eclipse-predicting math emerge from the corrosion.
The 2021 UCL paper that finally reconstructed the front dial — a display of Sun, Moon and planets that matched every fragment and every surviving word of the inscriptions.
