In 1929, Samuel Courtauld owned the most important collection of works by Paul Gauguin in England: five paintings, ten woodcuts and a sculpture. He subsequently sold two of the paintings, but for this show the gallery that bears Courtauld’s name has borrowed them back. One of them is the very beautiful ‘Martinique Landscape’ (1887), now owned by the National Galleries of Scotland, in which colour and pattern lock together in the most subtle and satisfying way.
