This book asserts that Oscar Wilde (1854 1900) was a major precursor of W.B. Yeats (1865 1939), and shows how Wilde's image and intellect set in train a powerful influence within Yeats's creative imagination that remained active throughout the poet's life. The intellectual concepts, metaphysical speculations and artistic symbols and images which Yeats appropriated from Wilde changed the poet's perspective and informed the imaginative system of beliefs that Yeats formulated as the basis of his dramatic and poetic work.
