W. H. Auden (1907-1973) was one of the wittiest and most worldly of English poetry's great twentieth century masters. His work ranges from the political to the religious, from the urbane to the romantic. He is also, with his exhilarating lyrical power and his understanding of love and longing in all their sacred and profane guises, an exemplary champion of human wisdom in its encounter with the mysteries of experience. More than any other poet, Auden used his poetry as an instrument to study the massive forces, dramas, and upheavals of the twentieth century, and his work displays an astonishing range of voice and breath of concern.
