You have contributions in medicine. The famous Hippocrates, the Hippocratic Oath, still has an influence on modern medicine. You have some of the earliest, what we could say, historians that we know of. Herodotus, famously giving us the accounts we have of the Greco-Persian Wars, a lot of what we even know about the ancient Persian Empire. You have Thucydides, who gives us accounts of the Peloponnesian War, along with Xenophon. And so when you see this density of arts, sciences, learning, in one place, a lot of this was centered in Athens, it makes you wonder what was going on at that time. And historians do call the period from when the Athenians were able to fend off the Persians all the way until the end of the Peloponnesian War as the Golden Age of Athens.
