In the arcaded cloisters were displays of numerous excavated artifacts. This was ancient Rome, with its wealth and power that anywhere you dig now you will find remnants of ancient Rome. Imagine in almost every Italian villa there are numerous such artifacts, in almost all the major museums in the world, there is a huge section with ancient Roman artifacts. Its no wonder the ancient Romans were such snobs that they call anyone who is not Roman a Barbarian. I was amazed when I was last at the New York Metropolitan museum of art that the Roman room stretched for miles (almost). Here in the cloisters were odds and ends but it was still fascinating.
