Iroquois. Nineteenth century. Wood, tin, horse hair. The Iroquois False Face Society was an association of healers. Their masks were living things that required care and nourishment, such as offerings of tobacco. The shaggy, contorted faces represent forest beings who gave gifts of healing to human beings. The most senior of the False Face masks represent the Great World Rim Dweller, a primordial being as old as the world itself.
