This is a very impressive collection of photos/artefacts! As these Romans have been colonizing pretty much all of Europe, we have Roman art around here as well:
In Nennig (Saarland / Germany) near the border to Luxembourg, a villa rustica was found. While the buildings were completely ruined, an entire intact mosaic floor was protected under meters of dirt for hundreds of years. It could be excavated and restored so we can enjoy it today.
It depicts gladiator scenes in exquisite detail. The level of artistry these people developed in ancient times is stunning, especially considering that much of the art we see today is of the "quick and dirty" home decoration variety that wasn't even meant to be "forever."
I hope you have a chance to come and visit us one day, so you can see this floor for yourself. Cheers from Germany - Folker
