Back a few years ago I had started to write a short story about a revival meeting. As in one from the First or Second Great Awakening, circa 1840s or so, probably in the Burnt-Over District in upstate NY. The interesting thing is that I wrote the story while trying to imagine how a good reenactor group would try it today. Find a good spot in the woods and/or the field (getting modern permits and all that), near some form of water supply (in reality having portable toilets and a water buffalo tank out of sight). Build a covered platform, set up the tents, park the wagons and the horses, and have a revival meeting with speakers most of the day.
My only stipulation research wise would be to say that all the public speakers, be they religious spiritual and so on, must stick to period religious topics
. Stepping onto my own personal soapbox, I cannot stand field church services at events where they use it as a platform for modern sermons. Save it for the podium back home, skippy; we want a period sermon, because, oh, I don't know, most of us came out here to experience a slice of nineteenth century history
?? Too much to ask for some folks, I see. Soapbox put away.
Researching, writing, rehearsing period sermons will require a lot more research, true. But - a lot of sermons are out there, online, un-condensed from their original two-hour format. So it can be done; it's just a question of people willing to take the time to try it. And training their voices to project without using a microphone. If you want that useful skill anyway, I'd suggest Toastmasters International. http://www.toastmasters.org/
Actually, they have a lot of skills reenactors could use in the field.
Civilian-only event, obviously, with a reason (okay, let's not lie, EXCUSE) to camp out, and in its best iteration three to four days. If anything it would give us a great opportunity to see just how much of an impact religion had on The Original Cast. And no, don't ask me to organize this because I have not the first clue how to go about doing this.
But I would attend . . .
