A truly cosmopolitan Irish writer, George Moore (1852-1933) was a fascinating figure of the fin de siècle, moving between countries, crossing genre and medium boundaries, forever exploring and promulgating aesthetic trends and artistic developments: Naturalism in the novel and the theatre, Impressionism in painting, Decadence and the avant-garde, Literary Wagnerism, the Irish Literary Revival, New Woman culture. This volume on border-crossings offers a variety of critical perspectives to approach Moore’s multifaceted oeuvre and personality. The essays by contributors from various national backgrounds and from a wide range of disciplines establish original points of contact between literary creation, art history, Wagnerian opera, gender studies, sociology, and altogether reposition Moore as a major representative of European turn-of-the-century culture.
