Canto III (The Revolt Of Islam) Percy Bysshe Shelley

1.
What thoughts had sway o'er Cythna's lonely slumber
That night, I know not; but my own did seem
As if they might ten thousand years outnumber
Of waking life, the visions of a dream
Which hid in one dim gulf the troubled stream
Of mind; a boundless chaos wild and vast,
Whose limits yet were never memory's theme:
And I lay struggling as its whirlwinds passed,
Sometimes for rapture sick, sometimes for pain aghast.

2.
Two hours, whose mighty circle did embrace
More time than might make gray the infant world,
Rolled thus, a weary and tumultuous space:
When the third came, like mist on breezes curled,
From my dim sleep a shadow was unfurled:
Methought, upon the threshold of a cave
I sate with Cythna; drooping briony, pearled
With dew from the wild streamlet's shattered wave,
Hung, where we sate to taste the joys which Nature gave.

3.
We lived a day as we were wont to live,
But Nature had a robe of glory on,
And the bright air o'er every shape did weave
Intenser hues, so that the herbless stone,
The leafless bough among the leaves alone,
Had being clearer than its own could be,
And Cythna's pure and radiant self was shown,
In this strange vision, so divine to me,
That if I loved before, now love was agony.
