First published in 1928, The Tower was Yeats's first collection published after receiving the Nobel Prize in 1923, and it is perhaps the major work that most cemented his reputation as one of the foremost literary figures of the twentieth century. The titular poem, 'The Tower', refers to Thoor Ballylee Castle, a Norman tower that Yeats purchased in 1917, and which formed the basis of the original cover design – evoked in the cover of this edition. The collection also includes some of his most inventive and profound work, and develops deep themes regarding life, love and myth. With explanatory notes, this edition seeks to bring the collection to a greater readership and to offer a more profound understanding of the great poet's work.
