Dennis Oppenheim, Parallel Stress, (1970)
Parallel Stress was a ten minute performance piece in which Oppenheim suspended his body between a masonry-block wall and a collapsed concrete pier in an industrial space between the Brooklyn and Manhattan Bridges. He held the position until his body also collapsed. He repeated the position over and over. Widening the gap between the walls. The photograph was taken at a point at which his body was at the point of greatest stress. Investigating the human body’s relationship to space and the materials of it’s industrial environment, Oppenheim used his body to record the stress encountered in bridging two structures. In a later work, this position was again assumed for one hour in an abandoned sump on Long Island.
