And you'll see, even in the 6th century BCE, this thread of Greek thinking, putting reason at a very high level, not just trying to explain everything with pure mysticism. Although Pythagoras definitely was, and Pythagoreanism was definitely about mysticism. But it was mysticism that at the core had mathematics and geometry. But continuing on with significant mathematical contributions from ancient Greece, we have Euclid. We don't know all of the exact details of his birth and his death. But he is the father of modern geometry. And as you can see in this map here, he didn't live in what we call Greece proper today.
