In the first 58 minute Performance, Relation in Space, which took place in July 1976 at the Biennale in Venice, Abramovic/Ulay, both naked, walk towards each other from opposite ends of a room, touching as they pass each other, and then they repeat the movement while their bodies collide and one of them (Marina) falls over under the impact, until they are both exhausted. A statically mounted video camera simultaneously filmed the touching of the bodies in the middle of the room.
