Cufalh is the trickster-demiurge of Nivaclé oral literature and the restless protagonist of its largest narrative cycle. In the mythic age he roams the world transforming it, settling the arrangements of present-day life while pursuing food, sex, and advantage through cunning. Many tales turn on his gluttony or on his own schemes rebounding upon him, yet the same episodes explain the origins of animals, foods, and social customs. He stands in the ambivalent middle ground between benefactor and fool that characterizes the Chaco transformer, comparable to the Wichí Tawkxwax and the Chorote Kixwet.
