Excerpt from Prometheus Unbound, Act 1 - Percy Bysshe Shelley

Monarch of Gods and Dæmons, and all Spirits
But One, who throng those bright and rolling worlds
Which Thou and I alone of living things
Behold with sleepless eyes! regard this Earth
Made multitudinous with thy slaves, whom thou
Requitest for knee-worship, prayer, and praise,
And toil, and hecatombs of broken hearts,
With fear and self-contempt and barren hope.
Whilst me, who am thy foe, eyeless in hate,
Hast thou made reign and triumph, to thy scorn,
O'er mine own misery and thy vain revenge.
Three thousand years of sleep-unsheltered hours,
And moments aye divided by keen pangs
Till they seemed years, torture and solitude,
Scorn and despair,--these are mine empire:--
More glorious far than that which thou surveyest
From thine unenvied throne, O Mighty God!
Almighty, had I deigned to share the shame
Of thine ill tyranny, and hung not here
Nailed to this wall of eagle-baffling mountain,
Black, wintry, dead, unmeasured; without herb,
Insect, or beast, or shape or sound of life.
Ah me! alas, pain, pain ever, for ever!

No change, no pause, no hope! Yet I endure.
I ask the Earth, have not the mountains felt?
I ask yon Heaven, the all-beholding Sun,
Has it not seen? The Sea, in storm or calm,
Heaven's ever-changing Shadow, spread below,
Have its deaf waves not heard my agony?
Ah me! alas, pain, pain ever, for ever!
