The Bride Stripped Bare by Her Bachelors, Even (), most often called The Large Glass (), is an artwork by Marcel Duchamp over tall and almost 6 feet (1.76m) wide. Duchamp worked on the piece from 1915 to 1923 in New York City, creating two panes of glass with materials such as lead foil, fuse wire, and dust. It combines chance procedures, plotted perspective studies, and laborious craftsmanship. Duchamp's ideas for the Glass began in 1912, and he made numerous notes and studies, as well as preliminary works for the piece. The notes reflect the creation of unique rules of physics, and myth which describes the work.

The Bride Stripped Bare by Her Bachelors, Even is also the title given to The Green Box notes (1934) as Duchamp intended the Large Glass to be accompanied by a book, in order to prevent purely visual responses to it. The notes describe that his "hilarious picture" is intended to depict the erotic encounter between the "Bride", in the upper panel, and her nine "Bachelors" gathered timidly below in an abundance of mysterious mechanical apparatus in the lower panel. The Large Glass was exhibited in 1926 at the Brooklyn Museum before it was broken during transport and carefully repaired by Duchamp. It is now part of the permanent collection at the Philadelphia Museum of Art. Duchamp sanctioned replicas of The Large Glass, the first in 1961 for an exhibition at Moderna Museet in Stockholm and another in 1966 for the Tate Gallery in London. The third replica is in Komaba Museum, University of Tokyo.

Visual analysis

The Large Glass consists of two glass panels, suspended vertically and measuring . The entire composition is shattered, but it rests sandwiched between two pieces of glass, set in a metal frame with a wooden base. The top rectangle of glass is known as the Bride's Domain; the bottom piece is the Bachelors' Apparatus. It consists of many geometric shapes melding together to create large mechanical objects, which seem to almost pop out from the glass and ever-changing background.

All forms on the glass are outlined with lead wire and filled in with earth tone oil paint. The colors range from pale grey to gold to dark brown and black. Some figures are bumpy and cloudy, and contain the dust left on them during the time which the unfinished work lay dormant, which seems to be an attempt at capturing the dynamic passage of time in a sedate work.

The Bride is a mechanical, almost insectile, group of monochrome shaded geometric forms located along the left-hand side of the glass. She is connected to her halo, a cloudy form stretching across the top. Its curvilinear outline and grey shading are starkly offset by the three undulating squares of unpainted glass evenly spaced over the central part of the composition. The Bride's solid, main rectangular form branches out into slender, tentacle-like projections. These include an inverted funnel capped by a half-moon shape, a series of shapes resembling a skull with two misplaced ears, and a long, proboscis-like extension stretching down almost as far as the horizon line between her domain and that of the bachelors. Her top-located domain is almost completely monochrome, with a wash of beige comparable to the cool colors of a cloudy sky.

The Bachelors' earthbound, lower domain, referred to by Duchamp as "La Machine Célibataire" (The Bachelor Machine), is a collection of much warmer, earthier colors of brown and golden tones. The Bachelors' Domain centers on the nine "Malic Molds". These dark brown shapes have a central vertical line, some with horizontal ones across them. They resemble the empty carcasses of clothes hanging from a clothesline, much more than they do actual men. They are interconnected through a spider web of thin lines, tying them to the seven conical cylinders. The cylinders range in color, and move in stages from nearly transparent on the left side, to translucent in the middle, to almost opaque on the far right. The opaque ones have swirling dark brown and gold colors and are almost solid three-dimensional forms, whereas the translucent ones are more ghostly outlines. They are connected in a line from tip to base and form a half circle. This rainbow-like shape is impaled centrally by a pole which connects them to the "chocolate grinder" at the lower part of the glass, and to the X-shaped rods that dominate the top center of the Bachelors' Domain.
