A Shakespeare Poem that has become a famous Halloween Quote

Song of the Witches: 

“Double, double toil and trouble”

BY WILLIAM SHAKESPEARE 

(from Macbeth: IV.i 10-19; 35-38 )

   Double, double toil and trouble; 

   Fire burn and caldron bubble. 

   Fillet of a fenny snake, 

   In the caldron boil and bake; 

   Eye of newt and toe of frog, 

   Wool of bat and tongue of dog, 

   Adder's fork and blind-worm's sting, 

   Lizard's leg and howlet's wing, 

   For a charm of powerful trouble, 

   Like a hell-broth boil and bubble. 

Double, double toil and trouble;    

Fire burn and caldron bubble. 

Cool it with a baboon's blood, 

Then the charm is firm and good.
