Sang old Tom the lunatic <br />That sleeps under the canopy: <br />'What change has put my thoughts astray <br />And eyes that had so keen a sight? <br />What has turned to smoking wick <br />Nature's pure unchanging light? <br /> <br />'Huddon and Duddon and Daniel O'Leary. <br />Holy Joe, the beggar-man, <br />Wenching, drinking, still remain <br />Or sing a penance on the road; <br />Something made these eyeballs weary <br />That blinked and saw them in a shroud. <br /> <br />'Whatever stands in field or flood, <br />Bird, beast, fish or man, <br />Mare or stallion, cock or hen, <br />Stands in God's unchanging eye <br />In all the vigour of its blood; <br />In that faith I live or die.'<br /><br />William Butler Yeats<br /><br />http://www.poemhunter.com/poem/tom-the-lunatic/
