On a Picture of a Black Centaur by W. B. Yeats

Your hooves have stamped at the black margin of the wood, Even where horrible green parrots call and swing. My works are all stamped down into the sultry mud. I knew that horse play, knew it for a murderous thing. What wholesome sun has ripened is wholesome food to eat And that alone; yet I, being driven half insane Because of some green wing, gathered old mummy wheat In the mad abstract dark and ground it grain by grain And after baked it slowly in an oven; but now I bring full flavoured wine out of a barrel found Where seven Ephesian topers slept and never knew When Alexander’s empire passed, they slept so sound. Stretch out your limbs and sleep a long Saturnian sleep; I have loved you better than my soul for all my words, And there is none so fit to keep a watch and keep Unwearied eyes upon those horrible green birds.
