I liked the way you referenced Freud's interpretation of Oedipus. I  also the riddle of the Sphynx it definitely depicts the lifecycle of Man. You also addressed the importance of theater and how in it's time Women and Slaves were excluded. Oedipus, as you also mentioned, is still important to art, history, and theater today and still draws great crowds. 

I didn't notice you mention that in its time, there were only men actors.
