These lines right over here are the lives of Socrates and Plato, who was Socrates' student, established the famous academy. Aristotle, who was Plato's student and famous tutor of Alexander the Great. Now as I mentioned, you had these city states. And the ones that are worth mentioning, or all of them are worth mentioning, but I have in this diagram the most significant city states of ancient Greece that you'll hear a lot about. We talked about the Oracle at Delphi, the Olympic Games at Olympia. A lot of the conversation tends to focus around Sparta and around Athens. And then you'll also hear a lot about Corinth and Thebes.
