In The Body Parlor, both man and sheep as combined sacrificial bodies become subjects of biological investigation. As symbols of ritual sacrifice, they are bodies that give of themselves. In discovering new forms of health-care (regenerative medicine) and tissue engineering (such as stem cell research), the body becomes sacrificial material for the greater purpose of a social good. The performers employ the material objects, either as products of or as extensions of the body as a way of exploring giving from one's self in sacrifice.
