This wasn’t just an ancient calendar…
It modeled the universe in motion.
Further analysis of the Antikythera Mechanism revealed a complex system of interlocking gears that modeled irregular lunar motion using a differential gear — a concept believed to have been invented in modern times — allowing ancient Greeks to simulate celestial mechanics with astonishing accuracy, demonstrating that theoretical astronomy, applied mathematics, and mechanical engineering converged in a single device over 2,000 years ago, and raising the uncomfortable question of how much advanced ancient knowledge was lost before it could be passed on.
