This is one of my favourite paintings Yellow Kidney of the
Piegan. Taken from the historical photographs of Edward S. Curtis. The Piegan sought the supernatural powers they believed were contained in the land and
in the animals. An animal would appear to them in a dream, providing the dreamer with instructions to obtain a particular power. The dreamer had to objects,
place them in a rawhide pouch, called a medicine bundle, and
engage in specified rituals and songs. The most powerful of these was the
beaver medicine bundle that the tribe used to allure buffalo.
