This document discusses the evolution of representation and abstraction in art from ancient times to the present. It begins by defining representation as the imitation or depiction of reality through signs and images. Aristotle viewed representation as a defining human activity. The document then outlines the history of representation in art forms like portraiture, landscape painting, and figurative works. In modern times, art has moved towards abstraction and non-representation. The document also discusses how performance art in the 1960s-70s introduced performative elements that challenged traditional notions of art. Contemporary artists now explore the performative power of images to produce real effects in the world.
