"The cuts that I made so far represent above all a philosophical space. But that which I am seeking, now, is no longer philosophical space but rather physical space. Two or three years have been enough, in fact, and space is no longer an abstraction, but has become a dimension which man can even inhabit, violating it with jets, with Sputniks, with space ships. It is a human dimension that can generate physiological pain, a terror in the mind, and I, in my most recent canvases, am trying to give form to this sensation" (Fontana quoted in G. Livi, "Incontro con Lucio Fontana", in Vanità, VI, no. 13, Fall 1962).
