Walter Horatio Pater (4 August 1839 – 30 July 1894) was an English essayist, art and literary critic, and fiction writer, regarded as one of the great stylists. His first and most often reprinted book, Studies in the History of the Renaissance (1873), revised as The Renaissance: Studies in Art and Poetry (1877), in which he outlined his approach to art and advocated an ideal of the intense inner life, was taken by many as a manifesto (whether stimulating or subversive) of Aestheticism.
