The Wild Swans At Coole

The trees are in their autumn beauty,  
The woodland paths are dry,  
Under the October twilight the water  
Mirrors a still sky;  
Upon the brimming water among the stones         
Are nine and fifty swans.  
  
The nineteenth Autumn has come upon me  
Since I first made my count;  
I saw, before I had well finished,  
All suddenly mount  
And scatter wheeling in great broken rings  
Upon their clamorous wings.  
  
I have looked upon those brilliant creatures,  
And now my heart is sore.  
All's changed since I, hearing at twilight,  
The first time on this shore,  
The bell-beat of their wings above my head,  
Trod with a lighter tread.  
  
Unwearied still, lover by lover,  
They paddle in the cold,  
Companionable streams or climb the air;  
Their hearts have not grown old;  
Passion or conquest, wander where they will,  
Attend upon them still.  
  
But now they drift on the still water  
Mysterious, beautiful;  
Among what rushes will they build,  
By what lake's edge or pool  
Delight men's eyes, when I awake some day  
To find they have flown away?
