El encanto de las brujas en Macbeth

Double, double toil and trouble;
Fire burn, and caldron bubble

Second Witch

Fillet of a Fenny Snake,
In the Cauldron boil and bake;
Eye of Newt, and Toe of Frogge,
Wool of Bat, and Tongue of Dogge,
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.

All
Double, double toyle and trouble,
Fire burn and Cauldron bubble.

Third Witch
Scale of Dragon, Tooth of Wolf,
Witches' Mummy, Maw and Gulf
Of the ravin'd salt Sea shark,
Root of Hemlock digg'd i' the dark,
Liver of Blaspheming Jew,
Gall of Goat, and Slips of Yew
Silver'd in the Moon's Eclipse,
Nose of Turk, and Tartar's lips,
Finger of Birth-strangled Babe
Ditch-deliver'd by a Drab,
Make the Gruel thick and slab:
Add thereto a Tiger's Chaudron,
For the Ingredients of our Cauldron.

All
Double, double toyle and trouble'
Fire burn and Cauldron bubble.

Second Witch
Cool it with a Baboon's blood,
Then the Charm is firm and good.

[Enter Hecate.]

Hecate
O! well done! I commend your pains,
And every one shall share i' the gains.
And now about the Cauldron sing,
Like Elves and Fairies in a Ring,
Enchanting all that you put in.

[Music, and a Song, 'Black Spirits,' and company.] ²
Song:
Black spirits and white, red spirits and gray;
Mingle, mingle, mingle, you that mingle may.

[Exit Hecate.]

Second Witch
By the pricking of my Thumbs,
Something wicked this way comes.
Open, Locks,
Whoever knocks.
