William Butler Yeats,
Sailing to Byzantium
(The Tower, 1927)

I. 
That is no country for old men.
The young In one another's arms, birds in the trees-
Those dying generations - at their song, 
The salmon-falls, the mackerel-crowded seas, 
Fish, flesh, or fowl, commend all summer long 
Whatever is begotten, born, and dies. 
Caught in that sensual music all neglect 
Monuments of unageing intellect. 

II.
An aged man is but a paltry thing,
A tattered coat upon a stick, unless 
Soul clap its hands and sing, and louder sing 
For every tatter in its mortal dress,
Nor is there singing school but studying 
Monuments of its own magnificence; 
And therefore I have sailed the seas and come 
To the holy city of Byzantium. 

III. 
O sages standing in God's holy fire
As in the gold mosaic of a wall, 
Come from the holy fire, perne in a gyre, 
And be the singing-masters of my soul. 
Consume my heart away; sick with desire 
And fastened to a dying animal 
It knows not what it is; and gather me 
Into the artifice of eternity. 

IV. 
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.
