Kubla Khan by Samuel Taylor Coleridge — Read

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

But oh! that deep romantic chasm which slanted / Down the green hill athwart a cedarn cover! / A savage place! as holy and enchanted / As e'er beneath a waning moon was haunted / By woman wailing for her demon-lover! / And from this chasm, with ceaseless turmoil seething, / As if this earth in fast thick pants were breathing, / A mighty fountain momently was forced: / Amid whose swift half-intermitted burst / Huge fragments vaulted like rebounding hail, / Or chaffy grain beneath the thresher's flail: / And 'mid these dancing rocks at once and ever / It flung up momently the sacred river. / Five miles meandering with a mazy motion / Through wood and dale the sacred river ran, / Then reached the caverns measureless to man, / And sank in tumult to a lifeless ocean: / And 'mid this tumult Kubla heard from far / Ancestral voices prophesying war!
