Author and Vatican scholar Roy Dolinger spent six years investigating Michelangelo’s work on the ceiling of the Sistine Chapel for his book The Sistine Secrets: Michelangelo's Forbidden Messages in the Heart of the Vatican and made some pretty neat discoveries. Among them was a putti (small angel) “making the fig”—sticking your thumb between your index and middle fingers, the Renaissance equivalent of flipping someone off—behind the back of the prophet Zechariah.
Why? Michelangelo modeled Zechariah on the then-current Pope, Pope Julius II, also known as Il Papa Terribile, the Fearsome Pope. It was Michelangelo’s way, Dolinger argues, of insulting the Pope in a subtle way. The gesture is so small that’s it’s difficult to see from the ground, which would be the only way Il Papa Terribile would have ever seen it.
