Sitting Bull 'Tatanka Iyotanka' (1834-1890). The spiritual leader and head of the Hunkpapa warrior societies, Sitting Bull poses in Barry's studio wearing a crucifix of brass and wood. It was presented to him in June of 1868 by 'Black Robe', Father Pierre Jean De Smet, who had been sent by General Sherman to bring Sitting Bull and his hostiles to council. Without Sitting Bull the 'Laramic Treaty' council took place at Fort Rice, D.T., July 2, 1868. (Harbaugh, P., 1982)
