Katsina or Kachina dolls are special figures that are exclusively made by the Hopi. The Hopi have inhabited Northern Arizona for more than a thousand years, and have strived to maintain their culture during that time. One tool the Hopi use to help preserve their culture is the Katsina doll or katsin tihu. Katsina Dolls are physical representations of the spirit beings of this world such as animals, plants, ancestors, and neighboring tribes. At a Katsina dance these dolls are given as gifts to Hopi girls by the katsinum as a way to teach Hopi children about their religion and to allow them to be more involved at an early age. Traditional katsina dolls are handmade out of cottonwood root and painted with natural pigments, and this is the style that can be found on the walls of Winter Sun.
