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 enamelling + 

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. + 
