The Iroquois have a legend that explains the origin of their healing masks. According to the legend, the Creator challenged a stranger to a mountain moving contest and banished the stranger when he tried to peek, leaving his face disfigured. Iroquois masks are carved onto living trees and used in healing rituals by the False Face Society to invoke spirits and cure the sick, who then join the society. The masks represent direct spiritual connections in Iroquois culture and were taken back by the Iroquois when they began being sold as artifacts for profit against their wishes.
