Then I got to thinking more about Joseph Campbell and the hero's journey. I got to thinking about a hook balanced with showing the World of Common Day.
Prologues seem like a great way to get the blood pumping, to hook the reader, while still allowing the author to introduce the hero's World of Common Day.
I know this has been discussed before, and I realize that the only rule is to do whatever works, but I think this gives support to the prologue beyond just artistic imperitive.
IMO there are only two rules for prologues.
1. Make them interesting
2. Make them relevant
I think I read elsewhere to also make them short, but I don't mind a long prologue.
That being said, I don't write prologues because I know too many people don't like them. I would if I thought it was needed, but I'm not sure if I will ever write a story that absolutely needs a prologue. There are always other ways to do things.
I would only do a prologue of there was a large time gap between the main story and the prologue narrative.
The key would be to show, not tell, what happens.
George R. R. Martin's prologue to Game of Thrones is a good one to discuss here. I think he wanted to establish the epicness of his series right away and understood that the slow build of his main arc would have made that difficult without a prologue. Truthfully, though, I would have liked the book better without the prologue because the process of discovering that bigger picture would have been deliciously drawn out. But that's because I trust George R. R. to deliver. A writer I didn't trust would have needed that prologue to pull me in.
I guess the point is to think carefully about what the prologue brings to the table. Does it show a REALLY integral scene the story cannot do without, or is it mostly background you can sprinkle into the main book? Could it be chapter one instead?
I.E. My 'prologue' is a dream of an event, a murder, happening elsewhere. Those murdered can't really stick arround to tell exactly what happened, and my protagonist doesn't meet anyone who knew the victims personally.
Bad example? good use?
