The coils, made from thin filaments about 3cm (1in) long, date from between 900BC and 700BC, according to Flemming Kaul of the National Museum in Copenhagen. But he and his colleagues aren't quite sure what they have found. "The fact is we don't know what they were for, although I'm inclined to think they were part of a priest-king's robes, perhaps a fringe on a head-piece or parasol, or maybe woven into cloth," he says on the museum's website . The gold spirals will go on display at Skaelskor City Museum next week.
