At the turn of the 1890s, Oscar Wilde refined his ideas about the supremacy of art in a series of dialogues and essays, and incorporated themes of decadence, duplicity, and beauty into his only novel, The Picture of Dorian Gray (1890). The opportunity to construct aesthetic details precisely, and combine them with larger social themes, drew Wilde to write drama. He wrote Salome (1891) in French in Paris but it was refused a licence. Unperturbed, Wilde produced four society comedies in the early 1890s, which made him one of the most successful playwrights of late Victorian London. At the height of his fame and success, while his masterpiece, The Importance of Being Earnest (1895), was still on stage in London, Wilde had the Marquess of Queensberry, the father of his lover, Lord Alfred Douglas, prosecuted for libel, a charge carrying a penalty of up to two years in prison. The trial unearthed evidence that caused Wilde to drop his charges and led to his own arrest and trial for gross indecency with other men. After two more trials he was convicted and imprisoned for two years' hard labour. In 1897, in prison, he wrote De Profundis which was published in 1905, a long letter which discusses his spiritual journey through his trials, forming a dark counterpoint to his earlier philosophy of pleasure. Upon his release he left immediately for France, never to return to Ireland or Britain. Oscar Fingal O'Flahertie Wills Wilde (1854 – 1900) was an Irish writer and poet. After writing in different forms throughout the 1880s, he became one of London's most popular playwrights in the early 1890s. Today he is remembered for his epigrams and plays, and the circumstances of his imprisonment which was followed by his early death.
