"Gleizes' individual development, his unique struggle to reconcile forces," writes the art historian Daniel Robbins, "made him one of the few painters to come out of Cubism with a wholly individual style, undeflected by later artistic movements. Although he occasionally returned to earlier subjects... these later works were treated anew, on the basis of fresh insights. He never repeated his earlier styles, never remained stationary, but always grew more intense, more passionate. () His life ended in 1953 but his paintings remain to testify to his willingness to struggle for final answers. His is an abstract art of deep significance and meaning, paradoxically human even in his very search for absolute order and truth." (Daniel Robbins, 1964)〔
