Fountain (Duchamp) in the context of "291 (art gallery)"

Conceptual art, also referred to as conceptualism, is art in which the concept(s) or idea(s) involved in the work are prioritized equally to or more than traditional aesthetic, technical, and material concerns. Some works of conceptual art may be constructed by anyone simply by following a set of written instructions. This method was fundamental to American artist Sol LeWitt's definition of conceptual art, one of the first to appear in print:

Tony Godfrey, author of Conceptual Art (Art & Ideas) (1998), asserts that conceptual art questions the nature of art, a notion that Joseph Kosuth elevated to a definition of art itself in his seminal, early manifesto of conceptual art, Art after Philosophy (1969). The notion that art should examine its own nature was already a potent aspect of the influential art critic Clement Greenberg's vision of Modern art during the 1950s. With the emergence of an exclusively language-based art in the 1960s, however, conceptual artists such as Art & Language, Joseph Kosuth (who became the American editor of Art-Language), and Lawrence Weiner began a far more radical interrogation of art than was previously possible (see below). One of the first and most important things they questioned was the common assumption that the role of the artist was to create special kinds of material objects.

L.H.O.O.Q. (French pronunciation: [ɛl aʃ o o ky]) is a work of art by Marcel Duchamp. First conceived in 1919, the work is one of what Duchamp referred to as readymades, or more specifically a rectified ready-made. The readymade involves taking mundane, often utilitarian objects not generally considered to be art and transforming them, by adding to them, changing them, or (as in the case of his work Fountain) simply renaming and reorienting them and placing them in an appropriate setting. In L.H.O.O.Q. the found object (objet trouvé) is a cheap postcard reproduction of Leonardo da Vinci's early 16th-century painting Mona Lisa onto which Duchamp drew a moustache and beard in pencil and appended the title.

A found object (a calque from the French objet trouvé), or found art, is art created from undisguised, but often modified, items or products that are not normally considered materials from which art is made, often because they already have a non-art function. Pablo Picasso first publicly utilized the idea when he pasted a printed image of chair caning onto his painting titled Still Life with Chair Caning (1912). Marcel Duchamp is thought to have perfected the concept several years later when he made a series of readymades, consisting of completely unaltered everyday objects selected by Duchamp and designated as art. The most famous example is Fountain (1917), a standard urinal purchased from a hardware store and displayed on a pedestal, resting on its back. In its strictest sense the term "readymade" is applied exclusively to works produced by Marcel Duchamp, who borrowed the term from the clothing industry (French: prêt-à-porter, lit. 'ready-to-wear') while living in New York, and especially to works dating from 1913 to 1921.

Found objects derive their identity as art from the designation placed upon them by the artist and from the social history that comes with the object. This may be indicated by either its anonymous wear and tear (as in collages of Kurt Schwitters) or by its recognizability as a consumer icon (as in the sculptures of Haim Steinbach). The context into which it is placed is also a highly relevant factor. The idea of dignifying commonplace objects in this way was originally a shocking challenge to the accepted distinction between what was considered art as opposed to not art. Although it may now be accepted in the art world as a viable practice, it continues to arouse questioning, as with the Tate Gallery's Turner Prize exhibition of Tracey Emin's My Bed, which consisted literally of a transposition of her unmade and disheveled bed, surrounded by shed clothing and other bedroom detritus, directly from her bedroom to the Tate. In this sense the artist gives the audience time and a stage to contemplate an object. As such, found objects can prompt philosophical reflection in the observer ranging from disgust to indifference to nostalgia to empathy.
