text: The ceremony opened with a Bison Dance, to call the buffalo to the people. It was followed by a variety of torturous ordeals through which warriors proved their physical courage and gained the approval of the spirits. The Okipa began with the young men not eating, drinking, or sleeping for four days. Then they were led to a hut, where they had to sit with smiling faces while the skin of their chest and shoulders was slit and wooden skewers were thrust behind the muscles. With the skewers tied to ropes and supporting the weight of their bodies, the warriors would be suspended from the roof of the lodge and would hang there until they fainted. To add agony, heavy weights or buffalo skulls were added to the initiates' legs. After fainting, the warriors would be pulled down and the men (women were not allowed to attend this ceremony) would watch them until they awoke, proving the spirits' approval. Upon awakening, the warriors would offer the left little finger to the Great Spirit, whereupon a masked tribesman would sever it with a hatchet blow. Finally, participants would endure a grueling race around the village called "the last race", until the thongs tied to the buffalo skulls ripped out of their skin.
