As a spokesman for aestheticism, he tried his hand at various literary activities: he published a book of poems, lectured in the United States and Canada on the new "English Renaissance in Art" and interior decoration, and then returned to London where he worked prolifically as a journalist. Known for his biting wit, flamboyant dress and glittering conversational skill, Wilde became one of the best-known personalities of his day. At the turn of the 1890s, he refined his ideas about the supremacy of art in a series of dialogues and essays, and incorporated themes of decadence, duplicity, and beauty into what would be 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 while in Paris but it was refused a licence for England due to an absolute prohibition on the portrayal of Biblical subjects on the English stage. Unperturbed, Wilde produced four society comedies in the early 1890s, which made him one of the most successful playwrights of late-Victorian London.
