Oscar Wilde (1854-1900) was one the main proponents of the idea of “art for art’s sake.” That is to say Wilde, a playwright, a poet, and a prose writer lived for the same beauty in life, which he tried to capture in his writing. A lot of Oscar Wilde’s work came to symbolize the decadence of the 1890s, the decade in which his life’s work truly flourished. Some of Wilde’s best-known works include The Picture of Dorian Gray (1891) and The Importance of Being Earnest (1895).
