Still at the Courtauld, nine works inspired by the seasons by this great American have been given to the gallery – and are a must-see for anyone with even a passing interest in modern art. The remarkable series offers a sort of traditional take on the seasons themselves (wintry snow, golden autumns, summer greenery, burgeoning spring) but sprinkles them with symbols of creativity, autobiography, art history and the relentless passage of time. A fascinating exhibition and a welcome addition to the Courtauld’s wonderful collection.
