It's a regular Kirchweih or church consecration festival, been going on for a few hundred years, and as I understand it the highlight is Burning Elisabeth -- she's a puppet tied to a treetop, looks kindof like a maypole in Franconia. The legend says that she was a legendary shrew, and one year her husband came up with the idea of tying her to a chair and hoisting it up into a tree in the forest for the Kirchweih festival so she wouldn't annoy everyone and he could get his jollies with the pretty young maidens. So the whole village agreed that was a good idea and they did. They stripped the tree of bark and branches so that no wild animals could get up to Lisbeth and harm her, how thoughtful. Everyone had a better time than they had for years, as Lisbeth had always been yelling at everyone to shut up and be moral and stuff like that. So when the festival was over (three days later!) they went out to the forest to get her down from the tree and as they neared, they could hear her yelling and ranting and raving -- she must've been screaming the whole three days. What a set of lungs. So they got closer and closer and were actually dreading taking her down, but hark -- thunder in the distance -- closer, closer -- BLAMMMMO! and the smell of burning wood. The screaming had stopped, but up in the sky! Flames! Crackling and popping! The husband fell to his knees and thanked God for his mercy, for relieving him and the village of the burden of Lisbeth.

The Gickelschmiß or Hahnenschlag: the Schläger's eyes are bound and he / she is turned about a few times and given a
flail, with which he attempts to hit a ceramic pot. Kindof like a pinata bwz. Pin the Tail on the Donkey. If he hits the pot (he doesn't have to smash it), he wins a live rooster (Gockel). And he is then required to provide a barrel of beer or apple wine for the group. I'd like to see that! The origins of this tradition? Less tragic than Elisabeth's tale: a young swain went a-drinking one fine evening, leaving for home only in the early early morn. Sneaking into his family's farmhouse, he tripped over a rooster in the yard, who let go a yell and woke the entire flock. In a sorry attempt to quiet the rooster, the fellow grabbed a flail and swung, shattering a ceramic pot but missing the poultry.

So anyhow the point is, I'll probably go to all these things: Saturday the parade at 17:00, Sunday the Bornheimer Museum is open all day as are the shops(!), and then
Wednesday Aug. 16 at 19:00 the Gickelschmiss, at 21:45 the Lisbethverbrennung. If you'd like to meet up, post here and we'll exchange handy numbers via PM. I haven't come up with any kind of unique marker that I could easily carry except for my green umbrella, which might not be so bad as I think it might rain anyhow...
