Our understanding the cosmos and our place in it has perplexed humanity for untold generations. The astronomers and geographers of the Hellenistic period were no different, looking to explain celestial phenomena and the nature of the Earth. Eratosthenes of Cyrene managed to calculate the circumference of the Earth to an astonishingly close value, Hipparchus did the same with the distance of the Moon, and Aristarchus of Samos proposed the earliest known model of heliocentrism 1800 years before Copernicus. The pinnacle of these theories came together was the incredible Antikythera Mechanism, the world's oldest analog computer, which will bring our series on science and technology to an end.
