Once out of nature I shall never take My bodily form from any natural thing, But such a form as Grecian goldsmiths make Of hammered gold and gold enameling To keep a drowsy Emperor awake; Or set upon a golden bough to sing To lords and ladies of Byzantium Of what is past, or passing, or to come.
Heaven blazing into the head: Tragedy wrought to its uttermost. Though Hamlet rambles and Lear rages And all the drop-scenes drop at once Upon a hundred thousand stages It cannot grow by an inch or an ounce.
William Butler Yeats (1865 - 1939)
