     William Butler Yeats, a most famous Irish writer, was born in Dublin on June 13, 1865. His childhood

lacked the harmony (和睦) that was typical of a happy family. Later, Yeats shocked his family by saying

that he remembered "little of childhood but its pain". In fact, he inherited (继承) excellent taste in art from

his family-both his father and his brother were painters. But he finally settled on literature, particularly

drama (戏剧) and poetry.

     Yeats had strong faith in the coming of new artistic movements. He set himself the fresh task in

founding an Irish national theatre in the late 1890s. His early theatrical experiments, however, were not

received favorably at the beginning. He didn't lose heart, and finally enjoyed success in his poetical

drama.

     Compared with his dramatic works, Yeats's poems attract much admiring notice. The subject matter

includes love, nature, history, time and aging. Though Yeats generally relied on very traditional forms, he

brought modern sensibility to them. As his literary life progressed, his poetry grew finer and richer, which

led him to worldwide recognition.

     He had not enjoyed a major public lift since winning the Nobel Prize in 1923. Yet, he continued

writing almost to the end of his life. Had Yeats stopped writing at age 40, he would probably now be

valued as a minor poet, for there is no other example in literary history of a poet who produces his

greatest works between the ages of 50 and 75. After Yeats's death in 1939, W. H. Auden wrote,

among others, the following lines:

     Earth, receive an honoured guest:

     William Yeats is laid to rest.

     Let the Irish vessel (船) lie.

     Emptied of its poetry.
