The Devil is in the details!

For 800 years, the 13th century painter Giotto must have been laughing in his grave at the joke he played on the pope.

Giotto was commissioned to paint a series of frescoes depicting the life and death of Saint Francis. Now, Chiara Frugone, an Italian art historian, has discovered a surprise in one of those pieces.

Yup! It's the DEVIL!!! Hooked nose, sinister eyes, and even horns!
