In the highlands of Colombia, two vanished worlds turned surplus into cosmology. The carvers of San Agustín left hundreds of megalithic statues, and the Muisca worked gold and made the famous raft that pictures the El Dorado ceremony, a gilded chief casting offerings into Lake Guatavita. Gold served as prayer thrown into sacred water, and as plunder for treasure hunters.
The El Dorado ceremony is known only through Spanish chroniclers writing after contact, so how often it happened is uncertain. San Agustín's monumental tradition ended centuries before the Spanish, though people kept living there, and its statue count varies by what is counted.
