When the spent sun throws up its rays on cloud And goes down burning into the gulf below, No voice in nature is heard to cry aloud At what has happened. Birds, at least must know It is the change to darkness in the sky. Murmuring something quiet in her breast, One bird begins to close a faded eye; Or overtaken too far from his nest, Hurrying low above the grove, some waif Swoops just in time to his remembered tree. At most he thinks or twitters softly, 'Safe! Now let the night be dark for all of me. Let the night be too dark for me to see Into the future. Let what will be, be.
Robert FrostPoetry begins in trivial metaphors, pretty metaphors, "grace" metaphors, and goes on to the profoundest thinking that we have. Poetry provides the one permissible way of saying one thing and meaning another. People say, "Why donโt you say what you mean?" We never do that, do we, being all of us too much poets. We like to talk in parables and in hints and in indirections - whether from diffidence or some other instinct.
