Devil Found in Detail of Giotto Fresco in Italy's Assisi

I guess devils are everywhere, some times even in churches.  After restoring one of the most famous artworks by Giotto in the basilica in the convent where St. Francis is buried, a devil figure was discovered in the clouds Reuters reports. 

It is not easy to see from the floor of the basilica,  but emerges clearly when seen up close. Or so they say...I still have a bit of trouble seeing it.  Does that mean I'm a little devilish?

 The chief restorer of the basilica stated the master probably did not want the image to be a big part of his artwork, and painted it among the clouds to have some fun. He may have wanted to spite someone he knew by portraying him as a devil in the artwork.That's how they did it in the 13th century. Maybe we should take lessons about being a little more subtle...
