Museo Archeologico Nazionale di Napoli and Napoli
Today was SUPPOSED to be a "light" day, though I think Steve and I have different definitions of "light".
The museum is in what was I've a 17th century palace, inhabited by a ruler who only cared to show off his status and wealth by collecting and displaying rare artifacts. He also had a "solar clock room", which was an expansive gallery room with a long mural ceiling where he had engaged mathematicians and astronomers to construct a working zodiac clock that would tell the time of the year by the sun's position at local noon every day. Unfortunately, due to timing and cloud cover, we did not get to see the marvel, though the room was still impressive. 
Pompeii artifacts including mosaics and musical instruments.
We started with a light breakfast outside of the hotel and visited Museo Archeologico Nazionale di Napoli.
