The poet William Bulter Yeats (1865 - 1939) was a lion of English and Irish literature in the 20th century, and was awarded the Noble Prize in Literature in 1923. His recognition so soon after Ireland's independence afforded him the opportunity to promote Irish nationalism and cultural independence. In addition to his accomplishments as a writer, Yeats founded the Abbey Theatre, spearheaded the Irish Literary Revival, and served in the Irish Senate for two terms late in his life.
Yeats grew up in Sandymount in County Dublin, Ireland and was schooled there and in London. He studied poetry at an early age, fascinated by Irish myths and the occult. The Island of Statues was his first significant poem. Yeats published his first book of lyrical work titled, The Wanderings of Oisin and Other Poems in 1889, comprising magical and fantasy pieces based on the Fenian Cycle of Irish mythology. His early works were clearly influenced by Percy Bysshe Shelley, Edmund Spenser, and William Blake. Yeats moved from Transcendentalism and a fascination with Irish mythology in his early years, to poetry more realistic and grounded in the physical since 1900.
After World War I, Yeats became disillusioned by the efficacy of democracy, lost much of his revolutionary spirit, and began favoring totalitarianism. He served as a Senator of the Irish Free State from 1922-1928. After winning the Nobel Prize, his book sales increased and he had enough wealth to pay off his family's debts. After many years of poor health, he underwent an operation, regaining his zeal for writing poetry, and dating younger women. In 1936, Yeats edited the Oxford Book of Modern Verse, 1892–1935. He passed away in 1939; his grave's epitaph was excerpted from his poem, Under Ben Bulben:
Cast a cold Eye On Life, on Death. Horseman, pass by!
