„How can you expect a beholder to experience my picture as I experienced it? A picture comes to me a long time beforehand; who knows how long a time beforehand, I sensed, saw, and painted it and yet the next day even I do not understand what I have done. How can anyone penetrate my dreams, my instincts, my desires, my thought, which have taken a long time to fashion themselves and come to the surface, above all to grasp what I put there, perhaps involuntary.“
— Pablo Picasso Spanish painter, sculptor, printmaker, ceramicist, and stage designer 1881 - 1973
1930s, Richard Friedenthal, (1963, p. 260).
