The Maya engineered the great pyramid at Chichén Itzá with exacting astronomical precision. At the spring equinox, shadows from the setting sun create the illusion of a giant serpent undulating down the staircase. The feathered serpent was widely worshipped across Mesoamerica—the Teotihuacanos a thousand years before the Aztecs, and Quetzalcoatl by the Aztec civilization—representing wind, rain, the morning star, creation, and civilization.
