The Moche culture of South America independently discovered and developed bronze smelting. Bronze technology was developed further by the Inca and widely used for utilitarian objects and for sculpture. A later appearance of limited bronze smelting in western Mexico suggests either contact of that region with Andean civilisations or separate discovery of the technology. The Calchaquí people of northwestern Argentina had bronze technology.Ambrosetti, El bronze de la región calchaquí, Buenos Aires, 1904.. Retrieved 28 March 2015.
