The moon's a steaming chalice,
Of honey and venom-wine.
A little of it sipped by night
Makes the long hours divine.
But oh, my reckless lovers,
They drain the cup and wail,
Die at my feet with shaking limbs
And tender lips all pale.
Above them in the sky it bends
Empty and gray and dead.
To-morrow night 'tis full again,
Golden, and foaming red.

Vachel Lindsay
