I was also very excited when Craig pointed out Michelangelo's self portrait in the rag clutched in the Last Judgement above the altar.
The Raphael Room was amazing as well. I did not realize The School of Athens was a fresco and not a canvas painting.
A fresco is the application of pigment on wet plaster, creating a bond that makes the painting actually part of the wall. It is newly restored and quite captivating. The room depicts 4 themes (one on each wall) Philosophy (School of Athens), Theology, Judgement, and Poetry. Each theme was distinct and fairly recognizable once you really studied the content. Of course various minds are represented in The School of Athens: Socrates, Plato, Copernicus, Goethe, etc...he even included his great rival Michelangelo!
Taking the subway back to our hotel, we got off on a whim to see the Piazza di Spagna, Spanish Steps and Trevi Fountain. The fountain is fed by aqueducts and the force of the flowing water allows it to spew out of the spouts without aid of pumps or electricity or anything. Of course as legend goes you must throw 2 coins over your shoulder to ensure your return...so I did!
