Quote (December 1903), as cited in Artists on Art, from the 14th – 20th centuries, ed. Robert Goldwater and Marco Treves; Pantheon Books, 1972, London, p. 444 Variant: The more horrifying this world becomes, the more art becomes abstract; while a world at peace produces realistic art. (this variant was quoted in the speech "Between Two Ages: The Meaning Of Our Times" by Wm. Van Dusen Wishard) commenting French Cubist art] ..Trees are violated, humans become incapable of life; there is a coercion that leads to the un-recognazibility of the object, to a picture-puzzle. For here what counts is not a profane law, but a law of art.

Zachary and Max Knight; publisher, University of California Press, 1964 Inventions” was a crucial series that helped solidify and launch Klee’s career. After he pursued painting, he still made time to make prints where he integrated ideas around Cubism, including the child-like aesthetic and the art of the mentally ill. Following this trip, he also created geometrically structured pictures such as Fire in the Evening. The Klee Society, founded in 1925 by the art collector Otto Ralfs, had made his second trip to the Orient possible, but he did not receive as many impulses as on his first trip to the Orient. Thus he wrote to his wife Lily: Color is primarily Quality. Secondly, it is also Weight, for it has not only color value but also brilliance. Thirdly, it is Measure, for besides Quality and Weight, it has its limits, its area, and its extent, all of which may be measured.Red Balloon is one of the most famous Paul Klee paintings that illustrate the artist’s exploration of geometric painting coupled with his personal symbolic style and development of an abstract pictorial language. The painting is not a red balloon alone but rather a whimsical cityscape made up of different geometrical shapes. This artwork was made during the period when Klee taught at the Bauhaus and reunited with Kandinsky. Diether Rudloff: Unvollendete Schöpfung. Künstler im zwanzigsten Jahrhundert.

Painted during his trip to Tunisia, Klee portrays an Abstract Expressionist or Cubist cityscape in watercolor, of which the style was most likely influenced by artists like Paul Cézanne. Fenster und Palmen, which translates to “Windows and Palm Trees” in English, is a study of the natural environment in a manner that does not imitate but serves as an analogous composition that utilizes a grid to help convey the scene. I project on the surface; that is, the essence of the subject must always become visible, even if this is impossible in nature, which is not adapted to this relief style. The absence of foreshortening also plays a crucial part in the process.. .For I have discovered a very small, undisputed, personal possession: a particular sort of three-dimensional representation on the flat surface.. .I am my style.
