Before the Castle of Petrella

Percy Bysshe Shelley

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:

§03Line by line

Stanza by stanza, with notes

  1. BEATRICE: They come not yet. / LUCRETIA: 'Tis scarce midnight.

    Editor's note

    The scene opens mid-wait. Beatrice fidgets with impatience while Lucretia attempts to ground her by pointing out that it’s not even midnight yet. Their first exchange reveals their contrasting temperaments: Beatrice is full of urgency, while Lucretia remains calm and measured.

  2. How slow / Behind the course of thought, even sick with speed, / Lags leaden-footed time!

    Editor's note

    Beatrice presents one of the play's most vivid images: thoughts race so quickly they become nauseating, while time lingers sluggishly behind. The term "leaden-footed time" captures the weight of waiting, making it feel physically burdensome. This reflects the mindset of someone whose thoughts have been in overdrive for an extended period.

  3. The minutes pass... / If he should wake before the deed is done?

    Editor's note

    Lucretia's fear is practical and immediate—what if the target wakes up? The ellipsis after 'pass' adds to the tension, stretching the stillness of the night into the text. At this moment, her anxiety isn't about morality; it's about logistics.

  4. 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.

    Editor's note

    Beatrice views the murder as a form of spiritual cleansing. By labeling her father as a 'spirit of deep hell' trapped in a human body, she removes his humanity, transforming the act of killing into an exorcism instead of a crime. This moral framework is what she has constructed to justify what she is about to do.

  5. 'Tis true he spoke / Of death and judgement with strange confidence / For one so wicked

    Editor's note

    Lucretia observes the unsettling contradiction in Count Cenci: he discusses God and death confidently, even though he's a deeply evil man. The fact that he dies 'without confession' disturbs her — in her Catholic perspective, even a monster deserves last rites. This reflects Shelley's exploration of the genuine moral complexity of the situation.

  6. Believe that Heaven is merciful and just, / And will not add our dread necessity / To the amount of his offences.

    Editor's note

    Beatrice presents a theological argument: God is just, so He won't judge them for this killing in the same way He judges Cenci for his crimes. The term 'dread necessity' is crucial — she isn't suggesting that the murder is a good thing, but rather that it's something unavoidable. She's appealing to Heaven to recognize this distinction.

  7. All mortal things must hasten thus / To their dark end. Let us go down.

    Editor's note

    Seeing the hired killers arrive below, Beatrice reflects profoundly: all living things rush toward death. There’s a sense of resignation or fate in her words. But before she can linger on this thought, the stage direction interrupts — they go down to meet the men. The weight of her insight and the suddenness of the action contrast sharply.

  8. How feel you to this work? / As one who thinks / A thousand crowns excellent market price / For an old murderer's life.

    Editor's note

    The hired killers, Olimpio and Marzio, have a completely different way of speaking — mercenary, darkly humorous, and almost laid-back. Marzio boils down the entire moral gravity of the scene to a simple transaction. This change in tone is intentional: Shelley illustrates that the same action can appear very different based on who is committing it and their motivations.

  9. It is the white reflection of your own, / Which you call pale.

    Editor's note

    When Marzio mentions Olimpio's pale cheeks, Olimpio quickly fires back with a sharp, almost clever reply. Yet the paleness is genuine — both are scared. This exchange shows that their bravado is masking their nerves, making them feel more human compared to their earlier detached conversation about 'market prices.'

  10. If one should bribe me with a thousand crowns / To kill a serpent which had stung my child, / I could not be more willing.

    Editor's note

    Olimpio shares his personal motive: Cenci has harmed him directly, like a serpent stinging a child. The serpent imagery ties back to the earlier portrayal of the 'spirit of deep hell' — Cenci is consistently depicted as something sub-human, venomous, and malevolent. Olimpio's readiness isn't merely for profit; it is deeply personal.

  11. That his death will be / But as a change of sin-chastising dreams, / A dark continuance of the Hell within him

    Editor's note

    Beatrice, upon learning that Cenci is drugged and asleep, envisions his death as a smooth transition from one form of torment to another. He is already trapped in an internal hell; dying simply makes it external and everlasting. This demonstrates impressive psychological and theological reasoning, highlighting how thoroughly Beatrice has considered this.

  12. Ye conscience-stricken cravens, rock to rest / Your baby hearts. It is the iron gate, / Which ye left open, swinging to the wind

    Editor's note

    When a noise startles the hired men, Beatrice snaps at them with disdain. She labels them 'conscience-stricken cravens' — cowards undone by their own guilt — and quickly points out that the noise is from the iron gate they left open. Her composure is unwavering. The last three lines, with their 'light, quick and bold' rhythm, sound almost like a battle command.

§04Tone & mood

How this poem feels

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.

§05Symbols & metaphors

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.

§07Historical context

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.

§08FAQ

Questions readers ask

Is this a poem or a play?

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.

What did Count Cenci do to Beatrice?

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.

Is Beatrice meant to be a hero or a villain?

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.

What does 'leaden-footed time' mean?

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.

Why does Beatrice call the murder a 'high and holy deed'?

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.

What is the significance of the midnight setting?

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.

Why does Lucretia worry about Cenci dying without confession?

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.

What happens after this scene?

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.
