“This concept is completely unknown as an idea about space-time, the space-time of a work, of a life, of an artist. Perhaps I have already said it, but maybe in this case you must always be clear: What is time? Basically, it is not possible to measure time. My time is not measured. At one moment it is painted with three or four figures and at another moment with only one figure. But the time itself cannot be measured.”
