The speaker says that he once saw a “damsel with a dulcimer,” an Abyssinian maid who played her dulcimer and sang “of Mount Abora.” He says that if he could revive “her symphony and song” within him, he would rebuild the pleasure-dome out of music, and all who heard him would cry “Beware!” of “His flashing eyes, his floating hair!” The hearers would circle him thrice and close their eyes with “holy dread,” knowing that he had tasted honeydew, “and drunk the milk of Paradise.”

Waking after about three hours, the poet seized a pen and began writing furiously; however, after copying down the first three stanzas of his dreamt poem—the first three stanzas of the current poem as we know it—he was interrupted by a “person on business from Porlock,” who detained him for an hour. After this interruption, he was unable to recall the rest of the vision or the poetry he had composed in his opium dream. It is thought that the final stanza of the poem, thematizing the idea of the lost vision through the figure of the “damsel with a dulcimer” and the milk of Paradise, was written post-interruption. The mysterious person from Porlock is one of the most notorious and enigmatic figures in Coleridge’s biography; no one knows who he was or why he disturbed the poet or what he wanted or, indeed, whether any of Coleridge’s story is actually true. But the person from Porlock has become a metaphor for the malicious interruptions the world throws in the way of inspiration and genius, and “Kubla Khan,” strange and ambiguous as it is, has become what is perhaps the definitive statement on the obstruction and thwarting of the visionary genius. 

Regrettably, the story of the poem’s composition, while thematically rich in and of itself, often overshadows the poem proper, which is one of Coleridge’s most haunting and beautiful. The first three stanzas are products of pure imagination: The pleasure-dome of Kubla Khan is not a useful metaphor for anything in particular (though in the context of the poem’s history, it becomes a metaphor for the unbuilt monument of imagination); however, it is a fantastically prodigious descriptive act. The poem becomes especially evocative when, after the second stanza, the meter suddenly tightens; the resulting lines are terse and solid, almost beating out the sound of the war drums (“The shadow of the dome of pleasure / Floated midway on the waves...”).
