"In the fall of 1912, Marcel Duchamp abandoned conventional painting and set about inventing new ways of working as an artist. Soon he was planning The Large Glass, and in 1915 he embarked on the eight-year process of fabricating the monumental construction. It is a compendium of Duchamp’s artistic obsessions: sexuality, chance, machines, humor, language games, and the workings of pictorial illusion. In the upper half of the picture, the Bride, a machine-insect hybrid, disrobes and exudes an erotic perfume. Permanently cut off from her in the lower zone are nine mannequin-like Bachelors, who respond by producing their own sexual gases which are then processed through an assortment of mechanical devices.": https://philamuseum.org/collection/object/54149
