Popol Vuh

There was nevertheless a tribe who stole the fire in the smoke; and they were from the house of Zotzil. The god of the Cakchiquel was called Chamalcdn and he had the form of a bat.

When they passed through the smoke, they went softly and then they seized the fire. The Cakchiquel did not ask for the fire, because they did not want to give themselves up to be overcome, the way that the other tribes had been overcome when they offered their breasts and their armpits so that they would be opened.
