On another forum, someone happened to ask about the origin of the term "martial." Someone said it was from the Greek god of war, but was immediately corrected. I.e., Ares was the Greek god of war; Mars was the Roman name. Anyway, so what did the Greeks call martial arts? Did they even have a term that encompassed martial arts?
Then, I thought of pankration because many people like to see it as the origin of mixed martial arts. However, afaik, pankration combined no holds barred boxing and wrestling. However, though pankration was definitely a sport, it was also definitely how Spartans trained for hand to hand combat.
Boxing is mentioned in Homer's Iliad. Well, maybe most of their games and sports were related to warfare. Throwing the javelin, running, and most of the ancient Olympic sports were martially practical.
