In the dim light of the Black Maria studios, William K.L. Dickson and William Heise turn their camera on one of history’s most fragile moments. Members of the Sioux tribe, adorned in war paint and traditional attire, perform a silent ritual before the lens. This early documentary work is shaped by the footsteps of three warriors known from Buffalo Bill’s shows. The figures, tracing circles to the deep, resonant sound of drums, bring traces of a vanishing cultural memory into the frame.
