Chiriguano

(map)

The evil supernatural being Aguara-Tunpa declared war against the god Tunpaete, Creator of the Chiriguanos. He set fire to the prairies in autumn, destroying all the plants and land animals. The people, who had not then begun farming, nearly died of hunger, but they retreated to the banks of rivers and survived on fish. Seeing people still surviving, Aguara-Tunpa caused a torrential rain. Acting on a hint given them by Tunpaete, the Chiriguanos placed two sibling babies, a boy and a girl, on a large mate leaf and set it afloat on the water. The flood rose, covering the earth and killing the rest of the Chiriguanos, but the two babies survived and eventually landed on solid ground when the flood sank. There, they found fish to eat, but they had no way to cook it. Fortunately, before the flood, a frog had taken some hot coals in his mouth, and it kept them alight during the flood by blowing on them. He gave the fire to the children, and they were able to roast their fish. In time, they grew up, and the Chiriguanos are descended from them.
