And all who heard should see them there,
And all should cry Beware! Beware!
His flashing eyes, his floating hair!
Weave a circle around him thrice,
And close your eyes with holy dread,
For he on honey-dew hath fed
And drunk the milk of Paradise

Kubla Khan by Samuel Taylor Coleridge (1772-1834)
When I painted this horse I named him “Xanadu” as he reminded me of this poem.
