The Rake's Progress
In the next scene Tom hates his marriage to Baba, who is a strange woman.  She is a  chatterbox with a fiery temper. He makes her quiet by throwing his wig over her face, then he falls asleep. Nick enters with a "fantastic Baroque Machine" which seems to turn stones into bread. Tom cries out in his sleep that he wishes it were true, and waking, finds the machine he has dreamt of.  Nick says to Tom that he could make a lot of money if he started a business making these machines.  Nick is deceiving him: the machine does not work.
