Theme of man and nature in Kubla Khan

In the poem, Kubla Khan, Coleridge explores the depths of dreams, and he creates landscapes that could not exist in reality. The “sunny pleasure-dome with caves of ice” exemplifies the extreme fantasy of the world in which Kubla Khan lives. Similar to a number of his other poems, the speaker’s admiration of the wonders of nature is clearly illustrated. In contrast to his other works, his depiction of nature is dangerous and threatening. An example of this can be seen in the following passage:

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 (lines 12-24)
