“A prisoner paints a landscape on the wall of his cell
showing a miniature train entering a tunnel. When his
jailers come to get him, he asks them politely to 'wait a moment, to allow me to verify something in the little train in my picture. As usual, they started to laugh, because they considered me to be weak-minded...I made myself very tiny, entered into my picture and climbed into the little train, which started moving, then disappeared into the darkness of the tunnel. For a few seconds longer, a bit of flaky smoke could be seen coming out of the round hole. Then this smoke blew away, and with it the picture, and with the picture, my person ...' How many times poet-painters, in their prisons, have broken through walls, by way of a tunnel! How many times, as they painted their dreams, they have escaped through a crack in the wall! And to get out of prison all means are good ones. If need be, mere absurdity can be a source of freedom.”
