A SUNDAY TIMES BOOK OF THE YEARThe ten years leading up to the First World War were the most exciting, frenzied and revolutionary in the history of art. They were the crucible of Modernism, when Fauvism, Expressionism, Cubism, Futurism and Abstract Art all burst forth. Simultaneously the Old Master market boomed, and art itself was politically weaponised in advance of approaching war. What was the conventional art against which Modernism was rebelling? Why did avant-garde artists become so obsessed with themselves? What persuaded a few bold collectors to buy difficult modern art? And why did others pay so much money for Old Masters? Art expert Philip Hook brings to bear a unique perspective on the art of a unique and extreme decade.
