"A Titus Andronicus catalogue of threats beat at the door"

Titus Andronicus is the most explicitly brutal of all Shakespeare's plays. After the newly wed Lavinia has been raped, the perpetrators cut out her tongue and chop off her hands so that she is unable to expose their identity. Other barbarisms include Titus's sons being served up to him on a plate and the rapists being baked in a pie and then eaten by their own mother.

From this play comes the rather satisfyingly unrepentant quote:

If one good deed in all my life I did
I do repent it from my very soul

It sounds like just the kind of thing a hubris filled Cavendish would say!
