There is a train track in the history of art that goes way back to Mesopotamia. It skips the whole Orient, The Mayas, And American Indians. Duchamp is on it. Cézanne is on it. Picasso and the Cubists are on it; Giacometti, Piet Mondrian, and so many... I have some feeling about all these people – millions of them – on this enormous track, a way into history. They had a peculiar way of measuring. They seemed to measure with a length similar to their own height... The idea that the thing that the artist is making can come to know for itself, how high it is, how wide and how deep it is, is a historical one, - a traditional one I think. It comes from man's own image.
