Was in Italy and I found "Gladiatores" a nice exhibit as its repro weapons and attire were all based on archeological artifacts.
The exhibit was held at the Colosseum in Rome by the way.
In the exhibit write-up, they also mentioned that they even simulated the ergonomics of the repro pieces they made, just to make sure that their reconstruction is sound.
Some sample pics are below. All of the 364 pics I took are
here. I took photos of all the displays and write-ups.
