In communities throughout Switzerlands’s Appenzell Hinterland and Midland regions, a unique tradition with enigmatic origins unfolds around the New Year. Known as Silvesterchlausen, the custom entails a group of boys and men who don remarkable, handmade costumes with masks and headdresses that represent rural, wild, and natural scenes.“Silvesterchlausen,” a dreamy short film by writer and director Andrew Norman Wilson, highlights this regional seasonal event, which occurs on December 31 and January 13. The first date marks the turn of the new year on the Gregorian calendar, while January 13 denotes the same on the Julian calendar. The ornately dressed mummers, in groups of six, polyphonically yodel and ring bells. “The ritual has been performed for at least 500 years, but nobody knows how or why it began,” Wilson says,Some of the performers’ headwear resembles miniature parade floats, while otherworldly designs made from pinecones, mosses, grasses, and other organic items make some of them appear as though they have emerged directly from the earth. In small, tight-knit municipalities, the tradition is a rare instance of relative anonymity, as familiar residents disappear behind meticulously crafted garments.The performers, known as Chläuse, practice diligently for a month or so before the event, creating something of a “Chläus fever.” Boys form the groups and “continue throughout their lives until the members are too old to withstand the physical toll of the 18 hour days,” Wilson says, sharing that the participants build significant bonds.As New Year’s Eve arrives, the mummers connect houses with a red string, literally and figuratively stitching connections within the community. Then, as the Chläuse move through villages and visit homes, local residents provide mulled wine to keep their bodies warm and spirits high.See the film on Vimeo, and find more of Wilson’s work on Instagram.
