JOYLESS EYE

"Art thou pale for weariness
Of climbing heaven and gazing of the earth, 
Wandering companionless
Among the stars that have a different birth, - 
And ever changing, like a joyless eye
That finds no object worth its constancy?"

Percy Bysshe Shelley, "To the Moon", in English Verse, Vol. IV, Oxford: Oxford University Press, 1977, p. 299.
