A bit of Kubla Khan

"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.."
--
..That sunny dome! Those caves of ice!
And all who heard should see them there,
And all should cry, Beware! Beware!
His flashing eyes, his floating hair!
Weave a circle round him thrice,
And close your eyes with holy dread,
For he on honey-dew hath fed,
And drunk the milk of Paradise."
--S.T. Coleridge
