Chichén Itzá, located on Mexico’s Yucatán Peninsula, is one of the country’s biggest and best preserved Mayan ruins. Every year on the Vernal Equinox, the angle of the sunlight hitting the enormous El Castillo pyramid creates a shadow that gives the illusion of a snake slithering down its side. The Mayans believed that this was Kukulcán, the feathered snake god known to the Aztecs as Quetzalcoatl. Tourists converge on the site on the equinox, and visitors enjoy folk dancers, musicians, and poets while they wait for the moment of the serpent’s appearance. Discuss
