Circles, circles everywhere. It's rumored that before Michelangelo was given the job of painting the Sistine Chapel, he was asked to provide proof of his artistic talent, perhaps because he was primarily a sculpture and there may have been some doubt that he was skilled enough with a brush to pull it off. When the envoys came to collect his pieces of formal, finished artwork to take back to the Pope, the artist supposedly dipped his brush into a lump of paint and on the spot, free-handed a perfect circle on blank canvas to make his point. I wonder where that canvas is today. Did some good nun dispose of it while cleaning out a church attic a long time ago, thinking, "It's nothing but a circle..."
