The Duchess of Malfi

John Webster's The Duchess of Malfi was written in the early 1600's and is often considered to be Webster's masterpiece. The story takes place in the Italian city of Amalfi during the sixteenth century, where the Duchess of the court of Amalfi is a young widow who has fallen in love with her steward, Antonio. Both of her brothers – the Cardinal and Duke Ferdinand – are against her remarrying and are very powerful. In becoming suspicious of the Duchess, Ferdinand hires Bosola to spy on her, while the Duchess thinks she has employed him as head of her stables. The Duchess unfortunately comes to have trust in Bosolo, and he discovers that she has married Antonio and had children with him in secret. As Ferdinand's spy, he reveals the information to the Duke, and is then ordered by Ferdinand to kill the Duchess. After the Duchess's secrets are revealed, the play unveils into great tragedy as the brothers seek out revenge that results in the death of the Duchess, Antonio, and their children; the Duchess's hand-maid, Cariola, Bosola, the Cardinal, the Cardinal's mistress and servant, and even Ferdinand. One of the motives often used in several other Jacobean plays is that of incest. It can be thought that incestual feelings for his twin sister, the Duchess, are the real reason that Ferdinand is so dead set on keeping his sister from remarrying. This is not obvious in the play, but implied, as there exists evidence of these feelings throughout the play. For example, he makes many sexual innuendos aimed at his sister throughout the entire play, such as we see here:
Ferdinand: And women like the part, which, like the lamprey,
Hath ne'er a bone in't.
Duchess: Fie, sir!
Ferdinand: Nay,
I mean the tongue [Act 1, Scene ii]
Also in Act 1, Ferdinand refers to his sister offensively as a "lusty widow." Another piece of evidence which hints at Ferdinand's possible incestuous feelings for his sister are in his last words, where he possibly shows recognition to these
