Uh, hmmmm, how do I break this to you since you obviously didn't read the article, or if you read it you didn't comprehend it. There is a big difference in knowing a painter purposely painted something onto his painting and pondering the reason he did it, and thinking and declaring that "gawd" made an image appear on it.

From the article:
The figure is difficult to see from the floor of the basilica but emerges clearly in close-up photography.
Sergio Fusetti, the chief restorer of the basilica, said that Giotto probably never wanted the image of the devil to be a main part of the fresco and may have painted it in among the clouds "to have a bit of fun."
The master may have painted it to spite someone he knew by portraying him as a devil in the painting, Fusetti said on the convent's website.
The artwork in the basilica in the convent where St. Francis is buried was last restored after it was severely damaged by an earthquake in 1997.

I think it's looks more like my aunt jemima, she was mean as hell, but made
great pancakes.
