Basel Fasnacht makes fun of all things sacred and profane. You cannot have a thin skin while watching a parade as each clique (with either drum and fife or a full size marching band) has a "sujet" subject or theme of their march. The subject and then the witty/cutting "so what" is displayed on a lighted "lanterna" that is paraded through the streets. This year there was the Pope - three times, a half dozen Swiss politicians, more than a few Elvis themes (one the holy Elvis - pope of American culture complete with a huge cortege wagon the size of a house that combined the pope mobile with a pink Cadillac), Paris Hilton, mosquitoes, and finally, a Chinese food theme, showing various fake animals in a hundred small cages worn on the top of the musician's hats towered over by a 15 foot high ape with an exposed brain and a man on top with chop sticks. It can be way over the top.
It is important to remember the history of Fasnacht. It originally was Carnival with the Dance of the Dead. After Reformation it was driven by the guilds who primarily were Protestant - the Pope has always been fair game. This is a letting go of a lot of pent up energy so to speak. The raucus all hours of the night partying and confetti throwing is in exact contrast to the usual quiet and polite Swiss culture. The absolutely spotless streets are covered in bottles, trash and 5 inches of confetti that looks like a rainbow snow storm. Thursday morning 04:00 the city was turned back to the street sweepers and those who bring order to to our lives here in Switzerland.
Lanterna in the form of Nazi realism describing the "pure" Swiss person as a parody on the worlds view of extreme Swiss nationalism.
