Mythology Summary
Kukulkan is the Yucatec Maya feathered serpent, known from the books of Chilam Balam and the colonial Yucatec sources as the civilising founder who came from the west, ruled at Chichen Itza and Mayapan, and departed over the sea promising to return. The identification with the Central Mexican Quetzalcoatl is traditional in the colonial sources, but how far the two are one figure is debated by scholars and the entry does not settle it. At El Castillo the setting sun throws a shadow-serpent down the north stair around the equinoxes: the effect is real, while the claim that the pyramid was deliberately built to mark the equinox is a modern interpretation.
Modern Practice
Kukulkan is called on by builders, teachers and founders, and for the work of returning: what went away is expected back and the return is not always comfortable. The Yucatec account is the primary one and the Mexican Quetzalcoatl is a relative, not the same lord under another name.
