Dee' (San Carlos Apache) and Ndee' (White Mountain Apache) is the hoop in the bottom left corner. The Lakota Medicine Wheel is bottom right.
The Apache hoop is used in traditional ceremonies and the type of ceremony determines whether a single hoop or four hoops are used. The hoop represents the cycle of life from birth to death. It possesses special powers which could be used, for example, to bless an individual when the hoop completely encircles the body. The hoop also has healing and protective powers.
The single Apache hoop has one of the four sacred colors to the tribe: black, green (blue), yellow and white. These colors represent the four directions, the four seasons, and the four major divisions of the day. An eagle feather is tied at four locations on the hoop. To the Apache, and almost all tribes, the eagle is a sacred bird and its feathers are believed to have special powers.
