According to Wikipedia: "Walter Horatio Pater (4 August 1839 - 30 July 1894) was an English essayist and critic of art and literary critic....his study of "Aesthetic Poetry" appeared in the Fortnightly Review, to be succeeded by essays on Leonardo da Vinci, Sandro Botticelli, Pico della Mirandola and Michelangelo. These, with other similar studies, were collected in his Studies in the History of the Renaissance in 1873. Pater, now at the centre of a small but interesting circle in Oxford, gained respect in London and elsewhere, numbering the Pre-Raphaelites among his friends.... by the time his philosophical novel Marius the Epicurean appeared, he had gathered quite a following. This, his chief contribution to literature, was published early in 1885. In it Pater displays, with fullness and elaboration, his ideal of the aesthetic life, his cult of beauty as opposed to bare asceticism, and his theory of the stimulating effect of the pursuit of beauty as an ideal of its own. The principles of what would be known as the Aesthetic movement were partly traceable to Pater and his effect was particularly felt on one of the movement's leading proponents, Oscar Wilde, a former student of Pater at Oxford. In 1887 he published Imaginary Portraits, a series of essays in philosophic fiction; Appreciations, with an Essay on Style was published in 1889 with a revised second edition in 1890; in 1893, Plato and Platonism; and in 1894, The Child in the House. His Greek Studies and his Miscellaneous Studies were collected posthumously in 1895; his romance Gaston de Latour appeared posthumously in 1896; and his essays from The Guardian were privately printed in 1897."
