“I have something real to offer. Instead of narrowing the field of vision, instead of absorption, a view of something giving, flowing, pulsating. Not the shrinking of the world in the cells of human imagination, but expansion on every side, the shooting of the viewer into space, where he can breathe deeply of fresh air. In this heaven is paradise on earth.” – Otto Piene, “Paths to paradise”, in: ZERO 3, Düsseldorf 1958; Reprint ZERO 1-3, Heinz Mack und Otto Piene, Cologne 1973, p. 148
“Light is my medium. Previously, paintings and sculptures seemed to glow. Now they do.” – Otto Piene quoted in “Otto Piene Obituary”, Charles Darwent, The Guardian, 24 July 2014.
