You know, a lot of times when we think about these things thousands of years later, it might seem somewhat romantic, the stuff of stories and adventures, but these things are ugly. People are getting killed, people are getting tortured, civilians are dying, whole cities are being destroyed. Now whenever we talk about history, it's very important to think about where your story is coming from, and you should always have a nice dose of doubt on what were the motivations of the person who wrote it, or how much can they really know about things? And when we talked about the Persian invasions of Greece, or the Greco-Persian Wars, that was coming to us from someone who is often known as the father of history. I guess that's a very Greco-centric perspective, but that is Herodotus. And now we're going to start getting our accounts from someone who wrote the famous history of the Peloponnesian War, and that is Thucydides. And they're so closely linked, especially because they're giving history of essentially this fifth century BCE, that this is actually a double bust of the two, Herodotus and Thucydides.
