Piero Dorazio (1927-2005)

'The surface of a canvas is a surface of two dimensions, and from that surface we make an optical phenomenon, we create an image that produces in the observer a sensation, an emotion, from all of which arises successively a problem, a reasoning, a thought, an idea, let us say in fact a mode of thought and of the spirit; if we do that, then we are in presence of art.' Piero Dorazio
