This shield is 18 Inches in diameter. We often think of shields as bearing heraldic symbols of brave and ferocious animals, such as grizzly bears and buffalo bulls, although as often as not the magical paintings portray the sky and the weather. This shield is a depiction of a sky scape with sun, moon, and stars. To the left, rain pours from the center disk, while to the right, a lightning bolt reaches out and forks to the rim of the shield, which represents the horizon of the earth. A personal medicine charm hangs in the center. This piece actually is a cover that cannot be removed to unveil the shield itself.
