"He [El Greco] has discovered a realm of new possibilities. Not even he, himself, was able to exhaust them. All the generations that follow after him live in his realm. There is a greater difference between him and Titian, his master, than between him and Renoir or Cézanne. Nevertheless, Renoir and Cézanne are masters of impeccable originality because it is not possible to avail yourself of El Greco's language, if in using it, it is not invented again and again, by the user."
