Dionysus was a deity/god? Think he was just a guy that jerked off to much in the streets of Athene and was probably the only one with enough balls to insult Alexander and convincing enough to actually make Alexander belief his insult was truth.
But I would probably go with... Vishnu.. ''Now I am become death, destroyer of worlds'' - Bagvad Gita
Can't think of a more perfect line in history.
Dionysus was a bit extreme in my opinion, but he sure did convey his principles and ultimately thats what a philosopher wants to do, Set an example.
