The Zuni Knife-wing God (A-tchi-a la-to-pa), a sky being, has a combined human-bird form. Though an animistic spirit, he holds no religious significance when rendered in silver but is merely decorative. As described by anthropologist Frank Hamilton Cushing, who lived with the Zunis from 1879-1884: "This curious god is the hero of hundreds of folklore tales, the tutelary deity of several societies of Zuni. He is represented as possessing a human form, furnished with flint knife-feathered pinions, and tail. His dress consists of the conventional terraced cap (representative of his dwelling place among the clouds)... His weapons are the Great Flint-Knife of War, the Bow of the Skies (the Rainbow), and the Arrow of Lightning. His guardians or warriors are the Great Mountain Lion of the North and that of the upper regions. He was doubtless the original War God of the Zunis."
