The poem
ENTER BEATRICE AND LUCRETIA. LUCRETIA: They are about it now. BEATRICE: Nay, it is done. LUCRETIA: I have not heard him groan. BEATRICE: He will not groan. LUCRETIA: What sound is that? BEATRICE: List! ’tis the tread of feet About his bed. LUCRETIA: My God! If he be now a cold, stiff corpse... BEATRICE: O, fear not _5 What may be done, but what is left undone: The act seals all. [ENTER OLIMPIO AND MARZIO.] Is it accomplished? MARZIO: What? OLIMPIO: Did you not call? BEATRICE: When? OLIMPIO: Now. BEATRICE: I ask if all is over? OLIMPIO: We dare not kill an old and sleeping man; His thin gray hair, his stern and reverend brow, _10 His veined hands crossed on his heaving breast, And the calm innocent sleep in which he lay, Quelled me. Indeed, indeed, I cannot do it. NOTE: _10 reverend]reverent all editions. MARZIO: But I was bolder; for I chid Olimpio, And bade him bear his wrongs to his own grave _15 And leave me the reward. And now my knife Touched the loose wrinkled throat, when the old man Stirred in his sleep, and said, ‘God! hear, O, hear, A father’s curse! What, art Thou not our Father?’ And then he laughed. I knew it was the ghost _20 Of my dead father speaking through his lips, And could not kill him. BEATRICE: Miserable slaves! Where, if ye dare not kill a sleeping man, Found ye the boldness to return to me With such a deed undone? Base palterers! _25 Cowards and traitors! Why, the very conscience Which ye would sell for gold and for revenge Is an equivocation: it sleeps over A thousand daily acts disgracing men; And when a deed where mercy insults Heaven... _30 Why do I talk? [SNATCHING A DAGGER FROM ONE OF THEM, AND RAISING IT.] Hadst thou a tongue to say, ‘She murdered her own father!’—I must do it! But never dream ye shall outlive him long! OLIMPIO: Stop, for God’s sake! MARZIO: I will go back and kill him. OLIMPIO: Give me the weapon, we must do thy will. _35 BEATRICE: Take it! Depart! Return! [EXEUNT OLIMPIO AND MARZIO.] How pale thou art! We do but that which ’twere a deadly crime To leave undone. LUCRETIA: Would it were done! BEATRICE: Even whilst That doubt is passing through your mind, the world Is conscious of a change. Darkness and Hell _40 Have swallowed up the vapour they sent forth To blacken the sweet light of life. My breath Comes, methinks, lighter, and the jellied blood Runs freely through my veins. Hark! [ENTER OLIMPIO AND MARZIO.] He is... OLIMPIO: Dead! MARZIO: We strangled him that there might be no blood; _45 And then we threw his heavy corpse i’ the garden Under the balcony; ‘twill seem it fell. BEATRICE [GIVING THEM A BAG OF COIN]: Here, take this gold, and hasten to your homes. And, Marzio, because thou wast only awed By that which made me tremble, wear thou this! _50 [CLOTHES HIM IN A RICH MANTLE.] It was the mantle which my grandfather Wore in his high prosperity, and men Envied his state: so may they envy thine. Thou wert a weapon in the hand of God To a just use. Live long and thrive! And, mark, _55 If thou hast crimes, repent: this deed is none. [A HORN IS SOUNDED.] LUCRETIA: Hark, ’tis the castle horn: my God! it sounds Like the last trump. BEATRICE: Some tedious guest is coming. LUCRETIA: The drawbridge is let down; there is a tramp Of horses in the court; fly, hide yourselves! _60 [EXEUNT OLIMPIO AND MARZIO.] BEATRICE: Let us retire to counterfeit deep rest; I scarcely need to counterfeit it now: The spirit which doth reign within these limbs Seems strangely undisturbed. I could even sleep Fearless and calm: all ill is surely past. _65 [EXEUNT.] SCENE 4.4:

Quick summary
This intense moment from Shelley's verse play *The Cenci* depicts Beatrice Cenci as she plots to kill her abusive father, Count Cenci.

Themes

Line-by-line

LUCRETIA: They are about it now. / BEATRICE: Nay, it is done.
The scene begins in the thick of action, with Lucretia and Beatrice caught in a tense silence. Their clipped, overlapping dialogue—each finishing the other's thoughts—creates an atmosphere of barely contained panic. Beatrice's assertion ('Nay, it is done') reveals her effort to view the murder as a done deal, a mental strategy to steady her nerves.
LUCRETIA: I have not heard him groan. / BEATRICE: He will not groan.
The exchange maintains its staccato rhythm. Beatrice's flat certainty ("He will not groan") sends a chill down the spine—she's thought this through enough to ensure the method will be silent. The victim's silence takes on a horror of its own.
BEATRICE: O, fear not / What may be done, but what is left undone: / The act seals all.
Beatrice reframes fear itself: the real danger lies not in committing the act but in leaving it unfinished. "The act seals all" is a pivotal line in the scene—it presents murder as a necessary legal or moral closure, the only thing capable of ending years of abuse. This line also hints at how Beatrice will rationalize the killing throughout the play.
OLIMPIO: We dare not kill an old and sleeping man; / His thin gray hair, his stern and reverend brow,
Olimpio's speech serves as a moral counterbalance to Beatrice's determination. He portrays Count Cenci with a surprisingly gentle touch—gray hair, hands crossed, and a peaceful sleep—and this vivid image of frail old age undermines the resolve of his hired assassin. Shelley intentionally draws the audience into this moment of doubt, even while we are aware of Cenci's actions toward Beatrice.
MARZIO: But I was bolder; for I chid Olimpio, / And bade him bear his wrongs to his own grave
Marzio pushes past Olimpio but is halted by something even more bizarre: the sleeping count mumbles a father's curse, and Marzio recognizes the voice of his deceased father within it. This moment blurs the lines between the two men — the abuser and the hired killer — leaving Marzio unable to distinguish between them. It stands out as one of Shelley's most insightful psychological nuances.
BEATRICE: Miserable slaves! / Where, if ye dare not kill a sleeping man,
Beatrice erupts. Her rage goes beyond mere impatience — it embodies the fury of someone who has lived through what the men have only fleetingly imagined. She flips their moral scruple on its head: the conscience that prevents them from killing has remained quiet amid "a thousand daily acts disgracing men." She seizes a dagger, making it clear she will take action alone if necessary. This moment marks the emotional climax of the scene.
BEATRICE: Even whilst / That doubt is passing through your mind, the world / Is conscious of a change.
After the killers leave to finish their task, Beatrice talks to Lucretia in a way that feels almost prophetic. She describes the world changing — darkness being pulled back into hell, her own blood flowing freely. The language blends the physical and the cosmic. Shelley gives Beatrice a form of ecstatic relief that is profoundly unclear: is this the tranquility of justice, or the dullness of someone who has crossed a line they can't return from?
BEATRICE [GIVING THEM A BAG OF COIN]: Here, take this gold, and hasten to your homes.
The act of paying the killers brings the scene back to a stark reality after Beatrice's inspiring speech. However, Shelley introduces a notable gesture: she hands Marzio her grandfather's mantle, the clothing of a man who was envied for his success. It's an unusual gift — both a reward and a symbolic transfer of status — and her last words to him, "This deed is none," declare that the murder isn't a crime, but rather a righteous act.
LUCRETIA: Hark, 'tis the castle horn: my God! it sounds / Like the last trump.
The horn announcing a visitor hits Lucretia like a thunderclap. Her comparison to the last trump — the trumpet of Judgment Day — suggests that the world of consequences is already tightening around her. The murder is complete, but the reckoning is just starting.
BEATRICE: Let us retire to counterfeit deep rest; / I scarcely need to counterfeit it now:
The scene ends with Beatrice's most haunting line. She intended to pretend to sleep as an alibi, but discovers she hardly needs to act — she truly feels at ease. Shelley leaves the audience pondering rather than providing a conclusion: is this the tranquility of someone who has done what was necessary and just, or the unsettling calm of someone who has turned off their own conscience?

Tone & mood

The tone remains tight, urgent, and filled with moral weight. Shelley uses compressed, dramatic language — quick exchanges that buzz with tension — before shifting to longer, more lyrical speeches as Beatrice takes charge. Her voice carries a chilling clarity that feels uncomfortable against the backdrop of the unfolding horror. The scene prevents any easy feelings of sympathy or straightforward condemnation.

Symbols & metaphors

  • The sleeping old manCount Cenci asleep serves as the scene's key moral image. His vulnerability while sleeping — with gray hair, crossed hands, and an innocent expression — is what unsettles the killers. Shelley employs this moment to compel the audience to grapple with two conflicting truths: this man is utterly helpless at this moment, and he has committed horrific acts.
  • The daggerWhen Beatrice grabs the dagger from one of the hired men, it symbolizes her reclaiming agency. Throughout the play, she has been a victim, but this moment marks her refusal to accept that role. It also shows that she is ready to take full moral responsibility for her actions.
  • The grandfather's mantleThe rich mantle Beatrice gives Marzio carries deep significance. It symbolizes inherited status and wealth, yet it also serves as a reminder of a family history marred by the very abuse she is working to end. Putting it on a hired killer could either be a true gesture of honor or an indication that the Cenci legacy of violence merely shifts from one person to another.
  • The castle hornThe horn that sounds after the murder is heard by Lucretia as the final trump — a call for divine judgment. It signals the moment when the world of consequences emerges, transforming the private act of killing into something that will be witnessed, examined, and evaluated.
  • Darkness and Hell swallowed upBeatrice's vision of darkness and hell pulling back into themselves portrays the murder as a cosmic correction instead of just a crime. In her eyes, Cenci represented the evil that tainted the world, and his death brings back a sense of natural order. Shelley presents this idea with empathy, while still allowing room for doubt about its truth.

Historical context

Shelley wrote *The Cenci* in 1819, inspired by the true story of Beatrice Cenci, a Roman noblewoman who was executed in 1599 for murdering her father, Francesco Cenci, after suffering years of abuse at his hands. The case gained notoriety throughout Europe, and a portrait thought to be of Beatrice—one that Shelley saw in Rome—profoundly affected him. Although he envisioned the play for the stage, he was aware it would be banned in England because of its themes (patricide and implied incest). This scene, Act 4 Scene 3, is the turning point of the entire drama: the moment when the plan comes to fruition. Shelley was living in Italy during a time of significant political and personal turmoil, and the play's exploration of tyranny, justice, and power corruption mirrors his broader radical views. *The Cenci* is often regarded as his greatest dramatic work.
