The poem
ENTER BEATRICE AND LUCRETIA ABOVE ON THE RAMPARTS. BEATRICE: They come not yet. LUCRETIA: ’Tis scarce midnight. BEATRICE: How slow Behind the course of thought, even sick with speed, Lags leaden-footed time! LUCRETIA: The minutes pass... If he should wake before the deed is done? BEATRICE: O, mother! He must never wake again. _5 What thou hast said persuades me that our act Will but dislodge a spirit of deep hell Out of a human form. LUCRETIA: ’Tis true he spoke Of death and judgement with strange confidence For one so wicked; as a man believing _10 In God, yet recking not of good or ill. And yet to die without confession!... BEATRICE: Oh! Believe that Heaven is merciful and just, And will not add our dread necessity To the amount of his offences. [ENTER OLIMPIO AND MARZIO BELOW.] LUCRETIA: See, _15 They come. BEATRICE: All mortal things must hasten thus To their dark end. Let us go down. [EXEUNT LUCRETIA AND BEATRICE FROM ABOVE.] OLIMPIO: How feel you to this work? MARZIO: As one who thinks A thousand crowns excellent market price For an old murderer’s life. Your cheeks are pale. _20 OLIMPIO: It is the white reflection of your own, Which you call pale. MARZIO: Is that their natural hue? OLIMPIO: Or ’tis my hate and the deferred desire To wreak it, which extinguishes their blood. MARZIO: You are inclined then to this business? OLIMPIO: Ay, _25 If one should bribe me with a thousand crowns To kill a serpent which had stung my child, I could not be more willing. [ENTER BEATRICE AND LUCRETIA BELOW.] Noble ladies! BEATRICE: Are ye resolved? OLIMPIO: Is he asleep? MARZIO: Is all Quiet? LUCRETIA: I mixed an opiate with his drink: _30 He sleeps so soundly... BEATRICE: That his death will be But as a change of sin-chastising dreams, A dark continuance of the Hell within him, Which God extinguish! But ye are resolved? Ye know it is a high and holy deed? _35 OLIMPIO: We are resolved. MARZIO: As to the how this act Be warranted, it rests with you. BEATRICE: Well, follow! OLIMPIO: Hush! Hark! What noise is that? MARZIO: Ha! some one comes! BEATRICE: Ye conscience-stricken cravens, rock to rest Your baby hearts. It is the iron gate, _40 Which ye left open, swinging to the wind, That enters whistling as in scorn. Come, follow! And be your steps like mine, light, quick and bold. [EXEUNT.] SCENE 4.3:

Line-by-line
BEATRICE: They come not yet. / LUCRETIA: 'Tis scarce midnight.
How slow / Behind the course of thought, even sick with speed, / Lags leaden-footed time!
The minutes pass... / If he should wake before the deed is done?
O, mother! He must never wake again. / What thou hast said persuades me that our act / Will but dislodge a spirit of deep hell / Out of a human form.
'Tis true he spoke / Of death and judgement with strange confidence / For one so wicked
Believe that Heaven is merciful and just, / And will not add our dread necessity / To the amount of his offences.
All mortal things must hasten thus / To their dark end. Let us go down.
How feel you to this work? / As one who thinks / A thousand crowns excellent market price / For an old murderer's life.
It is the white reflection of your own, / Which you call pale.
If one should bribe me with a thousand crowns / To kill a serpent which had stung my child, / I could not be more willing.

Ye conscience-stricken cravens, rock to rest / Your baby hearts. It is the iron gate, / Which ye left open, swinging to the wind
Tone & mood
The tone is tight and nighttime — the entire scene is filled with the tense anticipation of people poised to make an irreversible decision. Beatrice's voice comes across as fierce and confident, almost prophetic; Lucretia's sounds anxious and morally conflicted; the hired men's voice is grimly pragmatic. Shelley skillfully navigates through these tones, ensuring the scene avoids easy villainy or straightforward heroism. There's real dread in the air, but also a chilling, relentless courage that’s impossible to ignore.
Symbols & metaphors
- Midnight — The hour isn't merely a setting; it's a threshold. Midnight stands between one day and the next, the living and the dead, the decision and the act. Opting for this hour indicates that what unfolds here transcends ordinary time and moral boundaries.
- The iron gate swinging in the wind — The noise that startles the hired killers is just an open gate swaying in the wind. Yet, the image holds significance: an open gate represents an invitation or a means of escape, while the wind blowing in 'as in scorn' implies that nature is a detached, uncaring observer of the events about to unfold.
- Pale cheeks — Both hired men are pale, and they try to hide it. Their pallor reveals their fear and guilt — a truth their words are attempting to mask. This is the one moment in the scene where their bodies express what their mouths won't admit.
- The serpent — Olimpio's comparison of Cenci to a serpent that has stung a child taps into one of the oldest symbols of evil in Western tradition. This portrayal distances Cenci from humanity, making the act of killing him seem more like pest control than murder. Beatrice employs a similar reasoning with 'spirit of deep hell' — the serpent imagery reflects a version of that same dehumanization from the perspective of the hired man.
- Hell — Hell appears three times in the scene — as the source of Cenci's spirit, as the mental state he currently exists in, and as the conclusion that his death will solidify. It serves as both a religious concept and a psychological state. Shelley uses it to imply that the true hell in this story is what Cenci has already inflicted upon his family, rather than what they are planning to do to him.
- The opiate — Lucretia's action of mixing a sleeping drug into Cenci's drink is the only preparation that has taken place before the scene starts. This marks the point of no return — the moment the plan shifts from mere intention to actual execution. It also allows Beatrice to envision his death as a continuation of his drugged sleep, which she uses to find solace.
Historical context
Shelley wrote *The Cenci* in 1819, inspired by the real-life story of Beatrice Cenci, a young Roman noblewoman who was executed in 1599 for killing her father, Francesco Cenci. Known for his cruelty, historical accounts that Shelley referenced indicate that Francesco had sexually abused Beatrice. Shelley viewed the story as a tragedy where justice is twisted by tyranny — both from a monstrous father and a papal state that punished the victim instead of the abuser. He hoped the play would be staged at Covent Garden, but it was turned down due to its controversial subject matter. It didn't see a public performance in England until 1922. This scene, Act 4 Scene 3, serves as the turning point of the entire drama: the moment right before the murder that the whole play has been building up to.
FAQ
*The Cenci* is a verse drama, crafted entirely in blank verse, which means it uses unrhymed iambic pentameter. This particular scene stands out as one of the most intense moments in the play. Shelley wrote it with the intention of staging it, rather than merely reading it, but it faced a ban from the English stage for more than a hundred years.
Shelley never directly mentions it in the play — the act is described only in indirect, horrified terms — but both the historical context and the play itself make it clear that Francesco Cenci raped his daughter Beatrice. Shelley deemed the topic too horrific to address explicitly, which is why Beatrice's dialogue in the play is so indirect and filled with distress.
That’s the question Shelley wants you to ponder. In his preface, he mentions that Beatrice isn't a flawless moral character—she does make a mistake, even if her motivations are relatable. He aimed for audiences to experience the tragedy of someone pushed to wrongdoing by a larger evil, while still holding everyone accountable.
Lead is one of the heaviest metals, which is why 'leaden-footed' refers to moving with a heavy slowness. Beatrice is expressing that, despite her thoughts racing so quickly they make her feel nauseous, time itself still feels like it's dragging. It's a powerful way to illustrate the torment of waiting when you're already caught up in something dreadful.
Beatrice has persuaded herself — and is attempting to persuade the hired men — that killing her father isn't a sin but rather a form of divine justice. She portrays him as a demon in human guise, so getting rid of him feels more like an exorcism than murder. Whether Shelley agrees with this reasoning is another matter; he presents it as the thought process of someone facing an impossible situation.
Midnight has long been viewed as the hour of transgression, witchcraft, and crossing boundaries in Western literature. By choosing this time for the murder, the narrative steps away from the typical moral constraints of daylight. It also adds a layer of dramatic tension — with darkness, silence, and the constant threat of being overheard — which keeps the scene charged with danger, even during simple conversations between characters.
In Catholic theology, dying without confessing your sins to a priest means leaving this world in a state of unresolved sin, which could lead to damnation. Lucretia, a devout Catholic, struggles with the thought of condemning her husband to hell, despite her hatred for him, because she believes he deserves a chance to repent. This illustrates that her moral perspective is more traditional and conflicted compared to Beatrice's.
The murder occurs offstage — Shelley, adhering to classical dramatic conventions, avoids depicting it directly. In the subsequent scenes, the killers are apprehended, Marzio confesses after enduring torture, and Beatrice, Lucretia, and others are taken into custody. The play concludes with Beatrice's execution, which Shelley frames as a second injustice sanctioned by the state, adding to the weight of the first.
