Matisse: The Cut-Outs
Tate Modern, London, until 7 September
Shortly after Henri Matisse's death the writer and artist John Berger wrote a short illuminating essay on Matisse's work in which he remarked, "I can think of no modern artist with less interest in history or psychology." He was born in the year that the Cutty Sark was launched and died the year in which the first hydrogen bomb was tested.
