Archibald MacLeish (1892-1982)
                       
                     

                         Ars Poetica
                       
                        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.

deep and strong and strange
