It took 721 years and some close up photographies for someone to see it. AdvertisementIt's the devil—the face of a demon with black horns hidden in the clouds showing the heaven, just below two angels and San Francesco himself. It was discovered by medievalist Chiara Frugone while inspecting some close up photographies of the basilica's frescos. The basilica was restored after a major earthquake in September 1997, which completely destroyed other parts of the Franciscan buildings in Assisi.According to the historians, this is the first occurrence of a painter hiding something in the clouds. Sergio Fusetti, the basilica's chief restorer, said that it was probably a prank following a fight between Giotto and someone else. The painter may have decided to paint the profile of this person as the devil, immortalizing him forever without anyone really knowing about it.AdvertisementScientists keep discovering new details in Giotto's frescos. Recently, ultraviolet analysis of the Capilla Peruzzi, in the Basilica of the Holy Cross in Florence, have shown amazing details never seen before. The basilica's ceilings and walls were painted white years after Giotto finished his works, only to be poorly restored in the 19th century.
