Are angels small enough to dance on the head of a pin?

I always imagined that angels would be big, maybe even bigger than humans. They’d fly and hover and generally be pretty serious. It was hard to imagine one fitting on the head of a pin, much less ten. And imagining them dancing? It just seems like angels wouldn’t have much fun. Too much work to do. I have no idea where my image of angels comes from—maybe paintings? Pictures in books?

Where do you think your idea about angels comes from, and when you picture angels dancing on a pin, what does that picture look like?
