Context: The spectator experiences the phenomenon of transmutation; through the change from inert matter into a work of art, an actual transubstantiation has taken place... All in all, the creative act is not performed by the artist alone; the spectator brings the work into contact with the external world by deciphering and interpreting its inner qualifications and thus adds his contribution to the creative act.
