The voyeurism of Rear Window and the boundary between the private and public domains create a link to some of the central themes of modern art. The best known work dealing with the nature of voyeurism is undoubtedly Marcel Duchamp's Étant donnés: 1. La chute d'eau, 2. Le gaz d'éclairage (1944-66), which the artist was making at the same time as Hitchcock was making his film. Duchamp made his final work in complete secrecy as it was believed he had given up art altogether. Both the film and Duchamp's enigmatic work are studies in fixed eye central perspective, the interaction of intimate privacy and voyeurist gaze, and the intertwining of eroticism and violence. An intimate event becomes public once a district attorney becomes involved, in other words when a crime has been committed under the veil of privacy. In Duchamp's three-dimensional composition, a woman lying with her legs apart upon a reedy shore, a gas lamp raised in her left hand, is observed through two holes in an ancient Spanish timber door. In the background sparkles an electrically-operated illusionary waterfall. The young, fair-haired female figure's hairless pubes are indecently exposed directly in front of the viewer's eye in the dazzling light of a diorama. The perspective diorama composition suggests a narrative of sexual perversions or violence, but the event remains unexplained. The way in which the spectator's mind seeks a causal logic from the hints in Duchamp's construction, is reminiscent of the way Jeff perceives the logic of the series of episodes he sees from his window. Duchamp's work arouses a simultaneous feeling of scopophilic excitement and voyeuristic shame.
