I love this.<p>Nitpick: Rome was a city with a population of up to 1 million people plus millions of animals. We see a few plumes of smoke coming up from bath complexes, but that would just have been a few of thousands. Even if this was in the middle of day in the middle of summer, we should expect to see plumes of smoke coming up from tens of thousands of fireplaces. How else would they cook, bake bread etc. This was a very dense city, so I would expect to see haze over Rome even at noon in July. I would also expect to see soot on all the buildings and dirt in the streets.<p>I know this is just a model, but it leaves you with the impression that everything was white and clean, which sort of plays well with the thought of Rome as an advanced civilization that gave us a lot of our concepts and ideas for government and law. But it likely wasn't that pristine. It was probably a dirty, stinky, smoke filled, decease ridden place.<p>But still a wonderful model. I wish we had had these kinds of videos, when we sat through history classes.
