Hello, viewers. Today I’m standing at a 2,000-year-old Roman-era site. Here, the brightly colored scenes that once decorated a mansion are being dug up. These scenes are turning up in the southern French city of Arles, surprising the historians who have been working here since 2014. Patches of paint still cling to the stone walls of a bedroom and reception hall. Some of these painted walls are preserved in places to a height of one meter. In addition, thousands of fragments that fell off the walls have been recovered. These pieces have been put back together with great care and display a variety of images. Some of these images include figures never seen before in France, such as a woman playing a stringed instrument, possibly a character from mythology.
The paintings were done with such skill and with such expensive dyes that experts believe the artists originally came from Italy. They were likely hired by one of the city’s elite. Perhaps a Roman official wanted Pompeii-like interior to remind him of home. He was probably stationed in this provincial trading port, founded in 46 BC as a colony for veterans of the Roman army. Or maybe a wealthy local wanted to show off his worldly sophistication. The paintings may yield even more stunning surprises as additional sections are put together like pieces of a puzzle. Whoever it was that created such magnificent pieces of art, they surely had no idea that their work would still be around thousands of years later.
