Hell is empty and all the devils are here.
We meet this quote in the play “Tempest” written by William Shakespeare, Act 1, Scene 2, Page 10. It is said by Ariel, the magic spirit, reporting to its owner Prospero. Ariel was ordered to make a huge storm and set the ships of Prospero’s enemies on fire. Prospero doesn’t want them to get hurt, but to swim safely to his island and get what they deserve.
Nevertheless, they are still enemies, so Prospero asks if they were terrified enough and Ariel tells him that one of them - the king’s son, Ferdinand - was the first to jump into the water, with his hair up, screaming this phrase. Prospero is glad to hear such a details so he can enjoy his enemies’ horror.
