El Greco's re-evaluation was not limited to just scholarship. His expressiveness and colors influenced Eugène Delacroix and Édouard Manet. The first painter who appears to have noticed the structural code in the morphology of the mature El Greco was Paul Cézanne, one of the forerunners of cubism. Comparative morphological analyses of the two painters revealed their common elements, such as the distortion of the human body, the reddish and (in appearance only) unworked backgrounds, the similarities in the rendering of space etc. According to Brown, "Cézanne and El Greco are spiritual brothers despite the centuries which separate them". Fry observed that Cézanne drew from "his great discovery of the permeation of every part of the design with a uniform and continuous plastic theme".
