Tunisia! Detail from a Roman mosaic, Bardo Museum, Tunis
My wife and I went to Tunisia a couple of years ago, just before the Arab Spring and one of the places we visited in Tunis was the Bardo Museum, which has the largest collection of Roman mosaics in the world. We spent 4 hrs in the museum which wasn't enough except that sometimes enough is enough. Those folks had the mosaic process down to an art. Its hard to imagins they were over 2000 years old. More to come.
