Vasari relates that when Pope Benedict XI sent a messenger to Giotto, asking him to send a drawing to demonstrate his skill, Giotto drew a red circle so perfect that it seemed as though it was drawn using a pair of compasses and instructed the messenger to send it to the Pope.

Giotto got the papal gig. It’s fair to say I would not have.

I couldn’t resist some embellishment and tidying up.
