William Butler Yeats

Another Song Of A Fool

This great purple butterfly, In the prison of my hands, Has a learning in his eye Not a poor fool understands. Once he lived a schoolmaster With a stark, denying look; A string of scholars went in fear Of his great birch and his great book. Like the clangour of a bell, Sweet and harsh, harsh and sweet. That is how he learnt so well To take the roses for his meat.
