This rather early painting (1953) of an Indian scene by Frithjof Schuon features three chiefs smoking the sacred pipe in the foreground with, behind them, a shield on a tripod, a buffalo skull, warriors on horseback, and a double rainbow. The tipi in the center is dominated by an image of a sacred thunderbird.
