In the first authorized biography of W. B. Yeats for over fifty years, Roy Foster sheds new light on one of the most complex and fascinating lives of the late nineteenth and early twentieth century. Working from a great archive of personal and contemporary material, he dramatically alterstraditional perceptions to illuminate the poet's family history, relationships, politics and art.From a childhood inheritance of declasse Irish Protestantism with strong nationalist sympathies, and an exceptional and talented family background, the narrative charts Yeats's development into an original and outstanding poet. It ends in his fiftieth year with the controversies and disillusionmentaffecting his personal and public life at the time of the First World War. A bohemian life of uncertain finances, love-affairs, avant-garde friends and experiments with drugs and occultism prefaces his attempt to unite politics with high culture and his creation of an Irish national theatre.Constantly shifting between Dublin, Coole Park and London, with forays to America and Paris, ruthlessly constructing a public life as well as a creative reputation, Yeats's genius attracted admirers and enemies with equal passion. His story intersects with those of an engrossing cast of charactersincluding Lady Gregory, J. M. Synge, George Moore, `AE', Ezra Pound and above all Maud Gonne - an influence eternally re-created `like the phoenix', affecting almost everything he did.The search for supernatural wisdom forms a constant thread, traced through Yeats's occult notebooks and closely related to the insecurities of his personal life. The Apprentice Mage charts the growth of a poet's mind and of an astonishing personality, both of which were instrumental in theformation of a new and radicalized Irish nationalist identity.
