It is a small room decorated with frescoes and stuccoes. The frescoes show mythological episodes more or less inspired by The Metamorphosis, composed by the great Latin writer Ovidio. The episodes are painted inside rectangular frames in the upper part of the room. They nicely stand out against a light background and they are adorned with a particular decoration called “grottesche”. This is a type of pictorial decoration that, starting with Raphael, reflected the discovery of Rome's ancient houses that were splendidly decorated. Indeed during Renaissance the underground tunnels, so also the Roman ruins being unearthed, were called caves,“grotte”.
