Arrange these approaches to display in the order they appeared.

1. The Paris Salon hangs paintings frame to frame from the dado to the cornice
2. Whistler designs the room, the frames and the invitations for his 1883 exhibition
3. Alfred Barr's single-line hang on a white wall becomes the museum default in the 1930s
4. Duchamp webs the First Papers of Surrealism with a mile of string, 1942
5. Brian O'Doherty names the white cube and its ideology, 1976

The sequence is an argument running in both directions. The salon says a painting is one item in a market; the single line says it is an autonomous object; Whistler and Duchamp both say the room is part of the work; and O'Doherty, forty years after the white wall wins, points out that it was never neutral in the first place.
