Carbuncle (Latin America)
Carbuncle is a legendary species of small animal in South American folklore, specifically in the mining folklore of northern Chile. The animal is said to contain riches of some sort; in some versions it is a precious stone that gives fortune and good luck to its owner. It may originate from the medieval guivre, which was said to have a carbuncle on its head.
The description of the animal vary.One depiction was of the mirror in the carbuncle's head is said to be akin to two lights observed by Spanish explorers in the Strait of Magellan. Gonzalo Fernandez de Oviedo y Valdes identified these lights with the gemstones hidden in the brains of dragons. The association is likely derived from the 7th-century Etymologiae of Isidore of Seville.
