The marks in the picture evidently representing forked lightning, and
directed as in the language of the tradition at the forehead of the
beast, are without parallel among the Indian pictographs within the
writer's reach. The symbolic snake, or barbed zigzag of the Moquis--the
only Indian lightning that the writer has been able to find--differs
greatly from this, yet there seems no good reason why the Indian should
not have sometimes represented lightning as he saw it.
