IN XANADU

"In Xanadu did Kubla Kahn
A stately pleasure-dome decree:
Where Alph, the sacred river, ran
Trough caverns measureless to man
         Down to a sunless sea.
So twice five miles of fertile ground
With walls and towers were gridled round:
And there were gardens bright with sinuous rills,
Where blossomed many an incense-bearing tree;
And here were forest ancient as the hills,
Enfolding sunny spots of greenery.

But oh! that deep romantic chasm with slanted
Down the green hill athwart a cedam cover!
A savage place! as holy as enchanted
As e'er beneath a waning moon was haunted
By woman wailing for her demon-lover!"

Samuel Taylor Coleridge, "Visionary Fragments" in Selected Poetry, London: Penguin Books, 1994, p. 230.
