We visited this site in 2009 while they were still doing some restoration. They finished all of the work in 2012 and it is a joy to see. This is the site of the "bikini girls" if you have seen pictures of them.
Here are some photos that the Stoic One took.
We were told that the "Nike" shaped dark mosaics under the feet of the animals and people are not indeed trademarks of Nike but are used to denote movement. I wonder if the marketing people saw this before they developed their brand?
As you see the bikini girls are on a floor that was convered by another floor of mosaics, so it was the second floor. Why this was, no one knows. In modern times this mosaic is popular because it shows women participating in sports during Roman times. It is not clear what this room was used for. Interesting to speculate, but no one knows.
