Label Text"Tangbwal" spirits were called forth to regulate the food supply in preparations for ceremonial feasts. For about three to four months, masked dancers appeared in the village to issue and enforce a ban on the collection of coconuts so that a sufficient quantity would be available for the forthcoming event. When enough coconuts had ripened, the Tangbwal left the village on a mythical vessel represented by a platform in the shape of a canoe. The people showed great distress at the departure of the spirits, which was treated symbolically as a death. The dance costumes were destroyed after the cycle but the masks, called "lewa," were kept for the next time. It is generally accepted that, in the Lower Sepik River region, a long nose, like this one, represents a spiritual being, while a naturalistic nose portrays a true ancestor.
