A work of art, artwork, art piece, piece of art or art object is an aestheticphysical item or artistic creation. Except for "work of art", which may be used of any work regarded as art in its widest sense, including works from literature and music, these terms apply principally to tangible, portable forms of visual art:
This article is concerned with the terms and concept as used in and applied to the visual arts, although other fields such as aural-music and written word-literature have similar issues and philosophies. The term objet d'art is reserved to describe works of art that are not paintings, prints, drawings or large or medium-sized sculptures, or architecture. The term oeuvre is used to describe the complete body of work completed by an artist throughout a career.
criticized the idea that the work of art should be a unique product of an artist's labour, representational of their technical skill or artistic caprice. Theorists have argued that objects and people do not have a constant meaning, but their meanings are fashioned by humans in the context of their culture, as they have the ability to make things mean or signify something. Artist Michael Craig-Martin, creator of An Oak Tree, said of his work – "It's not a symbol. I have changed the physical substance of the glass of water into that of an oak tree. I didn't change its appearance. The actual oak tree is physically present, but in the form of a glass of water."
Some art theorists and writers have long made a distinction between the physical qualities of an art object and its identity-status as an artwork. For example, a painting by Rembrandt has a physical existence as an "oil painting on canvas" that is separate from its identity as a masterpiece "work of art" or the artist's magnum opus. Many works of art are initially denied "museum quality" or artistic merit, and later become accepted and valued in museum and private collections. Works by the Impressionists and non-representational abstract artists are examples. Some, such as the "Readymades" of Marcel Duchamp including his infamous urinal Fountain, are later reproduced as museum quality replicas. Research suggests that presenting an artwork in a museum context can affect the perception of it. There is an indefinite distinction, for current or historical aesthetic items: between "fine art" objects made by "artists"; and folk art, craft-work, or "applied art" objects made by "first, second, or third-world" designers, artisans and craftspeople. Contemporary and archeological indigenous art, industrial design items in limited or mass production, and places created by environmental designers and cultural landscapes, are some examples. The term has been consistently available for debate, reconsideration, and redefinition.
