In Act 1, Scene 3 of The Cenci, Count Cenci learns about his sons' deaths and he says: Here are the letters brought from Salamanca;
Beatrice, read them to your mother. God!
I thank thee! In one night didst thou perform,
By ways inscrutable, the thing I sought.
My disobedient and rebellious sons
Are dead!-Why, dead! -What means this change of cheer?
You hear me not, I tell you they are dead;
And they will need no food or raiment more:
The tapers that did light them the dark way
Are their last cost. The Pope, I think, will not
Expect I should maintain them in their coffins.
Rejoice with me--my heart is wondrous glad.
