PROMETHEUS UNBOUND.

Percy Bysshe Shelley

The variants of B. (Shelley’s ‘intermediate draft’ of “Prometheus Unbound”, now in the Bodleian Library), here recorded, are taken from Mr. C.D. Locock’s “Examination”, etc., Clarendon Press, 1903. See Editor’s Prefatory Note, above. 1. Act 1, line 204. B. has—shaken in pencil above—peopled. 2. Hark that outcry, etc. (1 553.) All editions read Mark that outcry, etc. As Shelley nowhere else uses Mark in the sense of List, I have adopted Hark, the reading of B. 3. Gleamed in the night. I wandered, etc. (1 770.) Forman proposes to delete the period at night. 4. But treads with lulling footstep, etc. (1 774.) Forman prints killing—a misreading of B. Editions 1820, 1839 read silent. 5. ...the eastern star looks white, etc. (1 825.) B. reads wan for white. 6. Like footsteps of weak melody, etc. (2 1 89.) B. reads far (above a cancelled lost) for weak. 7. And wakes the destined soft emotion,— Attracts, impels them; (2 2 50, 51.) The editio princeps (1820) reads destined soft emotion, Attracts, etc.; “Poetical Works”, 1839, 1st edition reads destined: soft emotion Attracts, etc. “Poetical Works”, 1839, 2nd edition reads destined, soft emotion Attracts, etc. Forman and Dowden place a period, and Woodberry a semicolon, at destined (line 50). 8. There steams a plume-uplifting wind, etc. (2 2 53.) Here steams is found in B., in the editio princeps (1820) and in the 1st edition of “Poetical Works”, 1839. In the 2nd edition, 1839, streams appears—no doubt a misprint overlooked by the editress. 9. Sucked up and hurrying: as they fleet, etc. (2 2 60.) So “Poetical Works”, 1839, both editions. The editio princeps (1820) reads hurrying as, etc. 10. See’st thou shapes within the mist? (2 3 50.) So B., where these words are substituted for the cancelled I see thin shapes within the mist of the editio princeps (1820). ‘The credit of discovering the true reading belongs to Zupitza’ (Locock). 11. 2 4 12-18. The construction is faulty here, but the sense, as Professor Woodberry observes, is clear. 12. ...but who rains down, etc. (2 4 100.) The editio princeps (1820) has reigns—a reading which Forman bravely but unsuccessfully attempts to defend. 13. Child of Light! thy limbs are burning, etc. (2 5 54.) The editio princeps (1820) has lips for limbs, but the word membre in Shelley’s Italian prose version of these lines establishes limbs, the reading of B. (Locock). 14. Which in the winds and on the waves doth move, (2 5 96.) The word and is Rossetti’s conjectural emendation, adopted by Forman and Dowden. Woodberry unhappily observes that ‘the emendation corrects a faultless line merely to make it agree with stanzaic structure, and...is open to the gravest doubt.’ Rossetti’s conjecture is fully established by the authority of B. 15. 3 4 172-174. The editio princeps (1820) punctuates: mouldering round These imaged to the pride of kings and priests, A dark yet mighty faith, a power, etc. This punctuation is retained by Forman and Dowden; that of our text is Woodberry’s. 16. 3 4 180, 188. A dash has been introduced at the close of these two lines to indicate the construction more clearly. And for the sake of clearness a note of interrogation has been substituted for the semicolon of 1820 after Passionless (line 198). 17. Where lovers catch ye by your loose tresses; (4 107.) B. has sliding for loose (cancelled). 18. By ebbing light into her western cave, (4 208.) Here light is the reading of B. for night (all editions). Mr. Locock tells us that the anticipated discovery of this reading was the origin of his examination of the Shelley manuscripts at the Bodleian. In printing night Marchant’s compositor blundered; yet ‘we cannot wish the fault undone, the issue of it being so proper.’ 19. Purple and azure, white, and green, and golden, (4 242.) The editio princeps (1820) reads white, green and golden, etc.—white and green being Rossetti’s emendation, adopted by Forman and Dowden. Here again—cf. note on (17) above—Prof. Woodberry commits himself by stigmatizing the correction as one ‘for which there is no authority in Shelley’s habitual versification.’ Rossetti’s conjecture is confirmed by the reading of B., white and green, etc. 20. Filling the abyss with sun-like lightenings, (4 276.) The editio princeps (1820) reads lightnings, for which Rossetti substitutes lightenings—a conjecture described by Forman as ‘an example of how a very slight change may produce a very calamitous result.’ B. however supports Rossetti, and in point of fact Shelley usually wrote lightenings, even where the word counts as a dissyllable (Locock). 21. Meteors and mists, which throng air’s solitudes:— (4 547.) For throng (cancelled) B. reads feed, i.e., ‘feed on’ (cf. Pasturing flowers of vegetable fire, 3 4 110)—a reading which carries on the metaphor of line 546 (ye untameable herds), and ought, perhaps, to be adopted into the text.

§01Quick summary

What this poem is about

Prometheus Unbound is Shelley's epic lyrical drama centered on the Titan Prometheus, who is chained and tortured by Jupiter (Zeus) for bringing fire to humanity. Unlike the ancient Greek version of the myth, Shelley's Prometheus does not succumb to hatred for his oppressor and is ultimately freed, resulting in a profound transformation of the world into a realm of love, equality, and beauty. It reflects Shelley's vision of a world where compassion and imagination replace tyranny and revenge.

§03Line by line

Stanza by stanza, with notes

  1. Act I — Prometheus bound on the icy cliffs of the Caucasus

    Editor's note

    The drama begins with Prometheus bound to a mountain, suffering endless torment at Jupiter's order. Instead of cursing Jupiter, Prometheus renounces his curse and chooses not to be defined by hatred. This distinguishes Shelley's interpretation from Aeschylus: the hero's strength arises not from rage-fueled defiance, but from a form of moral resilience. He feels pity for his oppressor rather than hatred, which is a bold notion — and Shelley uses it as a political commentary on the nature of true liberation.

  2. Act II — Asia descends into the realm of Demogorgon

    Editor's note

    Asia, Prometheus's beloved, ventures into the underworld to face Demogorgon, the primal force underlying everything. Their dialogue stands out as one of the most philosophically rich moments in English Romantic poetry. When Asia questions who is responsible for evil and suffering, Demogorgon declines to identify God as the answer — implying that the ultimate reasons are beyond our grasp of language. Asia's transformation in this scene, portrayed as a luminous blossoming, symbolizes the emergence of love as a transformative power in the world.

  3. Act III — Jupiter is overthrown; Prometheus is unbound

    Editor's note

    Jupiter doesn’t fall through violent upheaval; instead, Demogorgon rises and takes away the power that upholds tyranny. Hercules frees Prometheus, and that’s when change starts to happen. Shelley illustrates how oppressive systems can crumble when the inner agreement that supports them—fear, hatred, and submission—is removed. The Earth and Ocean rejoice in lyrical songs that depict a world revitalized by love, not one subjugated by force.

  4. Act IV — A cosmic celebration; the Moon and Earth sing to each other

    Editor's note

    The final act is almost entirely lyrical — a cosmic hymn where the Earth and Moon, spirits, and hours all celebrate the transformed universe. Shelley weaves together images of light, music, and movement to create a world where the human mind is finally liberated. The well-known closing lines, delivered by Demogorgon, serve as a moral takeaway: love, hope, and endurance are the forces capable of healing a fallen world. This act lacks any significant dramatic action; it is pure visionary poetry.

§04Tone & mood

How this poem feels

The tone shifts significantly throughout the four acts. Act I is filled with anguish and defiance, yet it remains controlled — Prometheus endures pain but does not succumb to bitterness. Act II becomes dreamy and mysterious, raising questions about power and origin. Act III is triumphant but subdued, leaning more towards relief than celebration. Act IV bursts forth with sheer ecstatic joy, its imagery of light and music almost overwhelming. Throughout, Shelley writes with a passionate intellectual intensity — he never presents a cool or detached perspective, but he is always engaged in thought, not just emotion.

§05Symbols & metaphors

Symbols & metaphors

Fire
Fire is the gift that Prometheus gave to humanity — it symbolizes knowledge, creativity, and the ability to build civilization. In Shelley's interpretation, it represents the strength of the human mind, which tyrants fear and seek to control.
The eagle
Jupiter's eagle tears at Prometheus's liver every day, symbolizing the relentless punishment that political and religious tyranny inflicts on those who have the courage to think freely and share knowledge.
Asia
Asia is both Prometheus's beloved and a representation of love as a cosmic principle. Her journey to Demogorgon and the transformation that follows illustrate that love isn't just passive; it actively drives liberation.
The cave
The cave where Prometheus and Asia go after his unbinding symbolizes a retreat into a life filled with creativity and intellectual exploration — a realm of imagination and beauty rather than a focus on political power. Shelley prioritizes inner freedom over worldly authority.
Demogorgon
This shadowy, nearly formless figure embodies the fundamental force behind all existence — something akin to necessity or eternity. He remains nameless and beyond full description, illustrating Shelley's belief that ultimate reality defies the labels tyrants wield to legitimize their power.
Light
Light is always present — in stars, lightning, the glow of Asia's transformation, and the 'sun-like lightenings' of Act IV. It represents reason, love, and the liberated imagination, which Shelley views as different expressions of the same essence.

§06Historical context

Historical context

Shelley wrote *Prometheus Unbound* mostly in Italy between 1818 and 1819, and it was published in 1820. At that time, Europe was experiencing political upheaval: the French Revolution had led to Napoleon's dictatorship, followed by the Congress of Vienna, which reinstated monarchies throughout the continent. Shelley, a radical thinker, argued that tyranny wasn't just upheld by military force but also by the mental patterns of those oppressed—fear, hatred, and the urge for revenge. He chose the Prometheus myth intentionally, opting for a version that diverged from Aeschylus's, where Prometheus ultimately makes a deal with Jupiter; instead, he presented a Titan who is liberated without compromise. The poem is also significantly influenced by Shelley's readings of Milton, Plato, and the political ideas of William Godwin, Mary Shelley's father. The textual notes in this edition highlight the poem's intricate manuscript history, including an intermediate draft that resides in the Bodleian Library at Oxford.

§07FAQ

Questions readers ask

It retells the Greek myth of Prometheus, the Titan who gave fire to humanity and was punished by Jupiter. Shelley transforms this story into a political and philosophical allegory: Prometheus symbolizes the free human mind, while Jupiter stands for tyranny—whether political, religious, or psychological. The poem explores how liberation occurs when people stop harboring hatred for their oppressors and withdraw their inner consent to being ruled by fear.
