The major Chibchan-speaking civilization, the Muisca, lived in Colombia. It was a powerful chiefdom known for intricate goldwork. The Muisca confederation was the source of the El Dorado legends, based on a real tradition in which a new king, smeared in sticky mud and then covered with gold dust, would dive into Lake Guatavita in Colombia, washing off the gold in the lake as an offering to the gods.
