Book excerpt: Drawing on secondary works in archaeology, art history, folklore, ethnohistory, ethnography, and literature, the authors maintain that the mask is the central metaphor for the Mesoamerican concept of spiritual reality. Covers the long history of the use of the ritual mask by the peoples who created and developed the mythological tradition of Mesoamerica. Chapters: (1) the metaphor of the mask in Pre-Columbian Mesoamerica: the mask as the God, in ritual, and as metaphor; (II) metaphoric reflections of the cosmic order; and (III) the metaphor of the mask after the conquest: syncretism; the Pre-Columbian survivals; the syncretic compromise; and today's masks.
