Postmodern art is a term used to describe an art movement which was thought to be in contradiction to some aspect of modernism, or to have emerged or developed in its aftermath. In general, movements such as Intermedia, Installation art, Conceptual Art and Multimedia, particularly involving video are described as postmodern.
There are several characteristics which define the term 'postmodern' in art; these include bricolage, the use of words prominently as the central artistic element, collage, simplification, appropriation, performance art, the recycling of past styles and themes in a modern-day context, as well as the break-up of the barrier between fine and high arts and low art and popular culture.
Postmodernism describes movements which both arise from, and react against or reject, trends in modernism. Specific trends of modernism that are generally cited are formal purity, medium specificity, art for art's sake, authenticity, universality, originality and revolutionary or reactionary tendency, i.e. the avant-garde. However, paradox is probably the most important modernist idea against which postmodernism reacts. Paradox was central to the modernist enterprise, having been introduced by Manet. Manet's various violations of representational art brought to prominence the supposed mutual exclusiveness of reality and representation, design and representation, abstraction and reality, and so on. The incorporation of paradox was highly stimulating from Manet to the conceptualists.
