Modern begins on a specific day—March 22, 1905—at a specific place: the Salon des Indépendants in Paris, where works of art we recognize as modern were first exhibited. Drawing on his forty five-year fine art career, author Philip Hook illuminates how this new art came to be—and how truly shocking it was. We witness movement upon movement that burst forth in dizzying succession: Fauvism, Expressionism, Primitivism, Symbolism, Cubism, Futurism, and Abstract art. His vivid accounts breathe new life into the work and times of nearly two hundred artists, and whose collective genius was understood and appreciated by few at the time. Hook reconsiders the decade from a series of fresh angles: What was the conventional art against which Modernism sought to rebel? Why were avant-garde artists so self-obsessed? And why did others pay so much money for Old Masters at the same time? Modern helps us answer these questions and more—and to see how avant-garde artists marshaled their genius (and oftentimes their madness) to create works of such profound consequence, they still reverberate today—and which, taken together, made for a movement more influential than even the Renaissance.
