Percy Bysshe Shelley: Prometheus Unbound Scene 3.1:

JUPITER:
Ye congregated powers of heaven, who share
The glory and the strength of him ye serve,
Rejoice! henceforth I am omnipotent.
All else had been subdued to me; alone
The soul of man, like unextinguished fire,[1]
Yet burns towards heaven with fierce reproach, and doubt,
And lamentation, and reluctant prayer,
Hurling up insurrection, which might make
Our antique empire insecure, though built
On eldest faith, and hell's coeval, fear;
And though my curses through the pendulous air,
Like snow on herbless peaks, fall flake by flake,
And cling to it; though under my wrath's night[2]
It climbs the crags of life, step after step,
Which wound it, as ice wounds unsandalled feet,
It yet remains supreme o'er misery,
Aspiring, unrepressed, yet soon to fall:
Even now have I begotten a strange wonder,
That fatal child, the terror of the earth,
Who waits but till the destined hour arrive,[3]
Bearing from Demogorgon's vacant throne
The dreadful might of ever-living limbs
Which clothed that awful spirit unbeheld,
To redescend, and trample out the spark.
Pour forth heaven's wine, Idaean Ganymede,
And let it fill the Daedal cups like fire,
And from the flower-inwoven soil divine
Ye all-triumphant harmonies arise,
As dew from earth under the twilight stars:
Drink! be the nectar circling through your veins
The soul of joy, ye ever-living Gods,
Till exultation burst in one wide voice
Like music from Elysian winds.
And thou
Ascend beside me, veiled in the light
Of the desire which makes thee one with me,
Thetis, bright image of eternity!
When thou didst cry, 'Insufferable might!
God! Spare me! I sustain not the quick flames,
The penetrating presence; all my being,
Like him whom the Numidian seps did thaw
Into a dew with poison, is dissolved,
Sinking through its foundations:' even then
Two mighty spirits, mingling, made a third
Mightier than either, which, unbodied now,
Between us floats, felt, although unbeheld,
Waiting the incarnation, which ascends,
(Hear ye the thunder of the fiery wheels
Griding the winds?) from Demogorgon's throne.
Victory! victory! Feel'st thou not, O world,
The earthquake of his chariot thundering up
Olympus?
[THE CAR OF THE HOUR ARRIVES.
DEMOGORGON DESCENDS, AND MOVES TOWARDS THE THRONE OF JUPITER.]
Awful shape, what art thou? Speak!

DEMOGORGON:
Eternity. Demand no direr name.
Descend, and follow me down the abyss.
I am thy child, as thou wert Saturn's child;
Mightier than thee: and we must dwell together
Henceforth in darkness. Lift thy lightnings not.
The tyranny of heaven none may retain,
Or reassume, or hold, succeeding thee:
Yet if thou wilt, as 'tis the destiny
Of trodden worms to writhe till they are dead,
Put forth thy might.

JUPITER:
Detested prodigy!
Even thus beneath the deep Titanian prisons
I trample thee! thou lingerest?
Mercy! mercy!
No pity, no release, no respite! Oh,
That thou wouldst make mine enemy my judge,
Even where he hangs, seared by my long revenge,
On Caucasus! he would not doom me thus.
Gentle, and just, and dreadless, is he not
The monarch of the world? What then art thou?
No refuge! no appeal!
Sink with me then,[4]
We two will sink on the wide waves of ruin,
Even as a vulture and a snake outspent
Drop, twisted in inextricable fight,
Into a shoreless sea. Let hell unlock
Its mounded oceans of tempestuous fire,
And whelm on them into the bottomless void
This desolated world, and thee, and me,
The conqueror and the conquered, and the wreck
Of that for which they combated.
Ai, Ai!
The elements obey me not. I sink
Dizzily down, ever, for ever, down.
And, like a cloud, mine enemy above
Darkens my fall with victory! Ai, Ai!
