2. Joseph Kosuth One and Three Chairs. 1965
One and Three Chairs, 1965, is a work by Joseph Kosuth. An example of conceptual art, the piece consists of a chair, a photograph of this chair, and an enlarged dictionary definition of the word "chair". The photograph depicts the chair as it is actually installed in the room, and thus the work changes each time it is installed in a new venue.
Two elements of the work remain constant: a copy of a dictionary definition of the word "chair" and a diagram with instructions for installation. Both bear Kosuth's signature. Under the instructions, the installer is to choose a chair, place it before a wall, and take a photograph of the chair. This photo is to be enlarged to the size of the actual chair and placed on the wall to the left of the chair. Finally, a blow-up of the copy of the dictionary definition is to be hung to the right of the chair, its upper edge aligned with that of the photograph.
Joseph Kosuth, WBAI, April 7, 1970:
"I used common, functional objects - such as a chair - and to the left of the object would be a full-scale photograph of it and to the right of the object would be a photostat of a definition of the object from the dictionary. Everything you saw when you looked at the object had to be the same that you saw in the photograph, so each time the work was exhibited the new installation necessitated a new photograph. I liked that the work itself was something other than simply what you saw. By changing the location, the object, the photograph and still having it remain the same work was very interesting. It meant you could have an art work which was that idea of an art work, and its formal components weren't important." [Siegel, Jeanne: Artwords. Discourse on the 60s and 20s.
