#443 โ€“ Gregory Aldrete: The Roman Empire โ€“ Rise and Fall of Ancient Rome

I did a book on floods where I had to get really heavy into vectors of disease and hydraulics and engineering and all that stuff. I think, again, having that sort of hard science combined with a humanist background helps with those sorts of projects.

I should say, by the way, it does drop out of use around Roman times. I think what's going on there is technology. With bronze, it's hard to keep a sharp edge on things, but once you get into metals which approximate steel, you can get sharper.

So as soon as you start to get something more like a razor edge, it's going to go through it more easily. Also, there's changes in the bows that are being used. You start to get sort of eastern horse archers showing up with composite bows, which are much more powerful. And so it just becomes outdated as frontline military equipment.

What's interesting is by the Roman period, people are still wearing it, but it's now things like when I go hunting, if I'm hunting lions, I wear this. There's an actual source that says it's really good for hunting dangerous big cats because it catches their teeth and stops them from penetrating. One emperor wears one of these under his toga.

It's kind of like a bulletproof vest, but stab-proof vest. So again, it's not to fight in the front line of the legions, but it'll protect him from somebody trying to assassinate him. So it still has those uses where you're not up against top-line military equipment.

One is he really just was a skilled individual, and he was one of those guys who had it all. He was smart, he was athletic, and he was supremely charismatic. I mean, it's obviously one of these people that would walk into a room and everyone just kind of gravitates to him. He had that magic that made him an effective leader.
