The dance is a physical embodiment of ritual. The mask is a physical vehicle for the dance, indexing the event in its absence. The structures of dance, exemplified by the mask, are a powerful means of ordering an architectural problem. The project analyzes and maps the physical and covert structures which exist within certain dances of the Northwest Coast Indians and applies these structures to the design of an exhibit space for the masks used in the rituals. By attempting to permeate the built form of the exhibit space with the structures of the dances, it is intended that a new dance will be created in the experience of the designed space.
