What is a favorite subject of the romantics and most evident in kubla khan?

A favorite subject of the Romantics was the exploration of the exotic, the mysterious, and the otherworldly. This is evident in Kubla Khan, a poem by Samuel Taylor Coleridge, which is full of vivid imagery and descriptions of a fantastical landscape. The poem begins with the line, "In Xanadu did Kubla Khan / A stately pleasure-dome decree," which immediately establishes a sense of the exotic and the mysterious. The poem goes on to describe the beautiful and strange landscape of Xanadu, including its "gardens bright with sinuous rills," its "sunny domes," and its "caves of ice." Coleridge's use of language in the poem is also highly evocative and sensory, creating a vivid and immersive experience for the reader.
