What are some good discussion topics for a thesis on Chiron?

Somehow I also thought there was a myth about Chiron and Sagittarius and how they relate. I am at work and don't have access to the book, but I can e-mail you later if you like.

you can google for details, but originally most centaurs were wild brash beasts who loved to eat drink and be merry, then came chiron who was a centaur but he was civilized and philosophical. i think he taught the other centaurs to reach for higher learning. one day at a feast with hercules and other centaurs a fight broke out and chiron was accidentally poisoned (by an arrow i think). when he died, zues put him in the stars so he could also be a god and live forever. thats where the constellation sagittarius comes from
