John Ruskin (1819–1900), British art critic, author. Letter, June 18, 1877. Fors Clavigera (1871-1884).
Referring to Whistler's Nocturne in Black and Gold: The Falling Rocket, Oscar Wilde commented that the painting was "worth looking at for about as long as one looks at a real rocket, that is, for somewhat less than a quarter of a minute." Whistler took more seriously Ruskin's remarks which he made the subject of a law-suit. See Whistler on value.
