Gladiator Scene

I believe this scene is after his fight with the gladiator Tigris of Gaul. My reasoning for this is that this was the first fight where he was actually struck by his opponent. We can see that the sunlight is directly on Maximus, which is to most likely indicate he is the hero. What I find most interesting is his armor. This is the armor that was given to him by Proximo before they traveled to Rome. My point is that he was given the armor before anyone knew his identity or story, yet on the left side it happens to have woman and child holding hands. Coincidence?
