this astonishing item, a drawing by the Sioux chief Black Hawk, of Black Hawk's War, of his personal visions:
This work is one of seventy-six drawings by Black Hawk that were bound into a book by William Edward Caton. Here, the artist depicts himself as a powerful supernatural being called a Destroyer. He rides a Buffalo Eagle, whose tail is represented by an arching rainbow. Spots representing hail cover both Buffalo Eagle and rider, and jagged power lines connect them.
