The poet Fernando Demaría in an essay "Xul Solar y Paul Klee" (published in the Argentine magazine "Lyra", 1971, and quoted extensively at [http://www.xulsolar.org.ar/xulxul.html]), wrote, "It is not easy for the human spirit to elevate itself from astrology to astronomy, but we would be making a mistake if we forget that an authentic astrologer, like Xul Solar, is close to the source of the stars... The primitivism of Xul Solar is anterior to the appearance of the Gods. The Gods correspond to a more evolved form of energy."
