“In Xanadu did Kubla Khan. A stately pleasure-dome decree:Where Alph, the sacred river, ran. Through caverns measureless to man. Down to a sunless sea.So twice five miles of fertile ground. With walls and towers were girdled round: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.”
– Samuel Taylor Coleridge, Kubla Khan
