The formative influences of Paris and France on the Anglo-Irish writer George Moore (1852–1933) cannot be underestimated. While the years Moore spent in Paris in the 1870s were seminal for his artistic awakening and development, the associations and friendships he formed in French literary and artistic circles exerted an enduring influence on his creative career. Moore maintained close ties with France throughout his life and his numerous contacts extended to social, musical and cultural spheres. He introduced the Impressionists to a British audience and his importation of French literary innovation into the English novel was remarkable. Exploring Moore’s early years in Paris and his ongoing engagement with the experimental modernity of his French models, these essays offer new insights into this cosmopolitan writer’s work. Moore emerges as a turn-of-the-century European artist whose eclectic writings reflect the complex evolution of literature from Naturalism to Modernism through Symbolism and Decadence.
