Round about the cauldron go;
In the poison'd entrails throw.
Toad, that under cold stone
Days and nights hast thirty‐one
Swelter'd venom sleeping got,
Boil thou first i' the charmed pot.
William Shakespeare, Macbeth

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.
William Shakespeare, Macbeth

Double, double toil and trouble;
Fire burn, and cauldron bubble.
William Shakespeare, Macbeth
