Kubla Khan (a variant spelling) is also the title and subject of a famous lyric poem by Samuel Taylor Coleridge, which opens:
|“|| In Xanadu did Kubla Khan
A stately pleasure-dome decree
The poem begins in iambic tetrameter, before "escalating" to iambic pentameter. Coleridge describes the "Dome of Pleasure" in iambic pentameter for some time, before the poem resumes in tetrameter, following this stanza:
|“|| The shadow of the dome of pleasure
Floated midway on the waves
Thereafter the poem discusses the author's attempts to re-live the experience of the pleasure dome:
|“|| I would build that dome in air.
That sunny dome! Those caves of ice!
The poem cuts thus off abruptly in a tone of yearning frustration. Poetic analysts suggest that the poem is an analogue to the creative process; the author struggles to get into the writer's ideal writing state, enters it, succeeds for a time, and ultimately fails, only to repeat the process again, hoping to achieve the strange and hypnotic beauty that defines true creativity (the "Pleasure Dome"). At the end, the author yearns to become a mythological, supreme creator... but can do no more than yearn.
Coleridge, who often used opium, said that he conceived of the poem and a good deal of its structure in an opium dream. When he awoke, he realized that he had composed some 500+ lines of poetry! He rushed to write it down, but claims that, while he was writing it, he was interrupted by "a person on business from Porlock." When he got back to his work, he was horrified to find that all the beautiful lines he had in his head were now completely forgotten. This "explanation" is Coleridge's attempt of giving a mythical explanation to the tetrameter-pentameter-tetrameter structure of the poem: the pentameter section (being more complicated) was inspired by his opium dream, while the sections in tetrameter were his attempts to frame and recall the dream.
This explanation ought to be disfavored, as it is likely Coleridge's attempt to ironically, cynically, and controversially link creativity with drug abuse. Coleridge was renowned for his sardonic wit, and this is but one more example.
