Shrinks to her second cause, and is no more.
     Physic  of Metaphysic  begs defence, 
     And Metaphysic  calls for aid on Sense ! 
     See Mystery  to Mathematics  fly! 
     In vain! they gaze, turn giddy, rave, and die.
     Religion  blushing veils her sacred fires, 
     And unawares Morality  expires. 
     Nor public  Flame, nor private , dares to shine; 
     Nor human  Spark is left, nor Glimpse divine ! 
     Lo! thy dread Empire, chaos! is restor’d; 
     Light dies before thy uncreating word: 
     Thy hand, great Anarch! lets the curtain fall; 
     And Universal Darkness buries All. (117)

This is the Night from which Joyce invites the Finnegans to 
wake.
