Definitely interesting stuff. One of the problems with tracing the history of Western martial arts is that so many of them were either daily "9-5" jobs training for "tribal" warriors early on (and therefore didn't have to be written down - see the Celts, Spartans, Huns, Roman gladiators, etc.) or were regimented military training (Roman soldiers). Most of the Eastern martial arts either a) survived into the modern day or b) were passed on in a modern form sometime in the 18th-20th centuries. Whereas the Western arts changed significantly in the 15th-18th centuries before being outclassed by firearms. So, a lot of Western martial arts were written down (see ARMA), but that only started happening in the 15th century, fairly late in their development and near the end of their days. In fact, a lot of them weren't written or formalized until after their battlefield use was extinct . . . so they were only useful as an artform, sport, or for dueling.
Case in point, take a look at modern Olympic Greco-Roman wrestling. If a modern wrestler trained in that form attempted to take on an original ancient Greek Olympian, the modern practitioner would be dead in a matter of seconds. Whereas a modern practitioner of, say, jujutsu might have a reasonable chance against a 14th century Japanese jujutsu practitioner, because that art hasn't changed too much.
