Visible and Invisible Structures in Renaissance Paintings

In order to emphasize the links between science and art, we analyze the Renaissance painting of the 15th century known under the name of „The Creation of the World and the Expulsion from Paradise”. This composition displays not only the artistic qualities, but also a symbolic meaning of the image following the internal geometric structure used by the Italian master when painting this masterpiece. The invisible structure is developed around three circles emphasizing the round halos of the Creator and of the Angel, as well as around the concentric circular universe depicted in the left half of the composition. A precise numerical ratio obtained through the expansion of these three circles reveals both the significance of all the elements distinguished in this wonderful piece of art.
