Shylock

Origin
In The Merchant of Venice, Shylock is a Jewish moneylender who lends money to his Christian rival, Antonio, setting the security at a pound of Antonio's flesh. When a bankrupt Antonio defaults on the loan, Shylock demands the pound of flesh, as revenge for Antonio having previously insulted and spat on him. Meanwhile, his daughter, Jessica, elopes with Antonio's friend, Lorenzo, and becomes a Christian, further fuelling Shylock's rage. She also takes money and jewels from Shylock.
