I think the creation mythologies that many martial arts, especially Chinese martial arts have, are pretty good stories.
Tibetan White Crane claims to have been created when a meditating Tibetan Lama witnessed a fight between a crane and a "mountain ape" (probably a macaque of some kind). Supposedly this lama, who was already an accomplished martial artists, took the circular running and long, swinging, pummelling punches from the ape, and combined it with the elusive and quick movements of the crane, and the art was born. At that time it was known as "Lion's Roar", which is a reference to the birth of the Buddha.
Later, when the art was brought into Southern China, it was known as Lama Pai, or "the style of the Lamas". One of its proponents (I forget the name for sure, but it might have been Wong Yan Lum) set up a challenge platform and welcomed all comers. Supposedly 150 people accepted his challenge and he defeated them all, killing many. And get this: he defeated everyone using the same two techniques.
I love stories like this. It would be interesting to know if there is any truth at all behind them.
