Turning and turning in the widening gyre   
    The falcon cannot hear the falconer;
    Things fall apart; the centre cannot hold;
    Mere anarchy is loosed upon the world,
    The blood-dimmed tide is loosed, and everywhere   
    The ceremony of innocence is drowned;
    The best lack all conviction, while the worst   
`
    Surely some revelation is at hand;
    Surely the Second Coming is at hand.   
    The Second Coming! Hardly are those words out   
    When a vast image out of Spiritus Mundi
    Troubles my sight: somewhere in sands of the desert   
    A shape with lion body and the head of a man,   
    A gaze blank and pitiless as the sun,   
    Is moving its slow thighs, while all about it   
    Reel shadows of the indignant desert birds.   
    The darkness drops again; but now I know   
    That twenty centuries of stony sleep
    Were vexed to nightmare by a rocking cradle,   
    And what rough beast, its hour come round at last,   
    Slouches towards Bethlehem to be born?
