At once praised and condemned by his contemporaries and by critics ever since for his highly complex poetic vision, William Butler Yeats remains one of the most important and controversial twentieth-century poets. In what has become a classic work of literary criticism, award-winning critic Harold Bloom breaks new ground with his radical interpretation of Yeats’ relationship to the English Romantic tradition. Yeats tells the continuous story of the lifelong influence of Shelley, Blake, and the Romantic tradition upon Yeats’ work. Through his analysis of the full spectrum of Yeats’ poems and plays, Bloom offers a profound reinterpretation of poetic influence in general.
