Literally, ‘master of men’. The supreme being of the Auca tribes of Chile, the staunchest opponents of Inca, and later Spanish, rule. He was also called Guinemapun, ‘master of the land’. His authority extended over natural phenomena and the fertility of men, animals, and plants. A parallel deity was Pillan, to whom were attributed such events as sudden storms, floods, and volcanic eruptions. But the ultimate source of ill was Guecufu, the malevolent spirit that sent the deluge.
