The Duchess of Malfi takes place in Italy, mostly at the Duchess’s palace in Malfi, in the sixteenth century. The Duchess is a young widow whose two brothers, Ferdinand and the Cardinal, are visiting her from Rome at the play’s start. Antonio, the manager of her household, has just returned from France.

The brothers are both incensed, but the Cardinal maintains a cool calm, whereas Ferdinand grows erratically angry. Neither of them realizes that she is married, and hence assume the baby is a bastard. Ferdinand says he won’t take any action until he knows who the baby’s father is.
Act Three begins about two years later, with Delio’s return to the
