The reason Milton wrote in fetters when he wrote of Angels and God, and at liberty when of Devils and Hell, is because he was a true poet and of the Devil's party without knowing it.
I asked a thief to steal me a peach: He turned up his eyes. I asked a lithe lady to lie her down: Holy and meek, she cries. As soon as I went An angel came. He winked at the thief And smiled at the dame- And without one word spoke Had a peach from the tree, And 'twixt earnest and joke Enjoyed the lady.
My silks and fine array, My smiles and languished air, By love are driv'n away And mournful lean Despair Brings me yew to deck my grave: Such end true lovers have.
