And there 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 all who heard should see them there, And all should cry, Beware! Beware! — Samuel Taylor Coleridge, "Kubla Khan, or A Vision in a Dream"
