Answer:
What surrounds the world, yet dwells within a thimble?
I am two-faced but bear only one. I have no legs but travel widely. Men spill much blood over me. Kings leave their imprint on me. I have greatest power when given away, yet lust for me keeps me locked away.
What has a single eye but cannot see?
You can see nothing else, When you look in my face, I will look you in the eye, And I will never lie.
I run around the city, but I never move.
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard. Who am I?
