Hélio Oiticica's artistic practice moved through a number of discrete, though related, conceptual phases, each with its own distinctive articulation and each bounding one or more series of works. Each successive phase of Oiticica's work developed out of his attempt to resolve
the challenges raised by a preceding phase. His work was explicitly dialectical in this sense and its philosophical sophistication marks its distinctiveness in ways that are only beginning to be recognised. In the work the artist developed in New York between 1970 and 1978, elaborating on
the concept of ‘creleisure’ that he had conceived in London in 1969, Oiticica proposed nothing less than a revolution in the idea of aesthetic revolution. Creleisure was a neologism that combined the senses of creativity, faith, leisure and pleasure, but in order to understand
the concept's full significance it is necessary to trace its relation to the aesthetics of Schiller and Marcuse and Latin American foquismo theory.
