Ars Poetica 
By Archibald MacLeish
A poem should be palpable and mute   
As a globed fruit, 
Dumb 
As old medallions to the thumb, 
Silent as the sleeve-worn stone 
Of casement ledges where the moss has grown — 
A poem should be wordless   
As the flight of birds. 
A poem should be motionless in time   
As the moon climbs, 
Leaving, as the moon releases 
Twig by twig the night-entangled trees, 
Leaving, as the moon behind the winter leaves,   
Memory by memory the mind — 
A poem should be motionless in time   
As the moon climbs. 
A poem should be equal to: 
Not true. 
For all the history of grief 
An empty doorway and a maple leaf. 
For love 
The leaning grasses and two lights above the sea — 
A poem should not mean   
But be.
