The Large Glass

Duchamp worked on his complex Futurism -inspired piece The Bride Stripped Bare by Her Bachelors, Even (The Large Glass) from 1915 to 1923, except for periods in Buenos Aires and Paris in 1918–1920. He executed the work on two panes of glass with materials such as lead foil, fuse wire, and dust. It combines chance procedures, plotted perspective studies, and laborious craftsmanship. He published notes for the piece, The Green Box, intended to complement the visual experience. They reflect the creation of unique rules of physics, and a mythology which describes the work. He stated that his "hilarious picture" is intended to depict the erotic encounter between a bride and her nine bachelors.

A performance of the stage adaptation of Raymond Roussel 's novel Impressions d'Afrique, which Duchamp attended in 1912, inspired the piece. Notes, sketches and plans for the work were drawn on his studio walls as early as 1913. To concentrate on the work free from material obligations, Duchamp found work as a librarian while living in France. After immigrating to the United States in 1915, he began work on the piece, financed by the support of the Arensbergs.

The piece is partly constructed as a retrospective of Duchamp's works, including a three-dimensional reproduction of his earlier paintings Bride (1912), Chocolate Grinder (1914) and Glider containing a water mill in neighboring metals (1913–1915), which has led to numerous interpretations. The work was formally declared "Unfinished" in 1923. Returning from its first public exhibition in a shipping crate, the glass suffered a large crack. Duchamp repaired it, but left the smaller cracks in the glass intact, accepting the chance element as a part of the piece.

Joseph Nechvatal has cast a considerable light on The Large Glass by noting the autoerotic implications of both bachelorhood and the repetitive, frenetic machine; he then discerns a larger constellation of themes by insinuating that autoeroticsm – and with the machine as omnipresent partner and practitioner – opens out into a subversive pan-sexuality as expressed elsewhere in Duchamp's work and career, in that a trance-inducing pleasure becomes the operative principle as opposed to the dictates of the traditional male-female coupling; and he as well documents the existence of this theme cluster throughout modernism, starting with Rodin's controversial Monument to Balzac, and culminating in a Duchampian vision of a techno-universe in which one and all can find themselves welcomed.

Until 1969 when the Philadelphia Museum of Art revealed Duchamp's Étant donnés tableau, The Large Glass was thought to have been his last major work.
