Prayer to the mystery. When praying her; the pipe was always offered to the Grand Manitou by raising it to heaven. At the feet of the worshiper is a buffalo skull; symbolizing the spirit of the animal on which the Indians depended so much. The man we see in this photograph is Picket Pin; a Sioux Oglala (Ogalala). Photo taken from volume 3 of Edward S. Curtis's encyclopedia (1868-1952) on North American Indians; with a foreword by Theodore Roosevelt. Between 1907 and 1930; 20 volumes were published. ©Gusman/Leemage
