In Norwegian knitting, a selburose (), also known as an åttebladrose or an eight-pointed star is a knitted rose pattern in the shape of a regular octagram. It is traditionally used for winter clothing such as the Selbu mitten (selbuvott) and sweaters (lusekofte, lopapeysa and mariusgenser). Of ancient origin, the pattern is associated with Selbu Municipality in Norway, and has become an international symbol of Norway (or Scandinavia generally), Christmas and winter.
History
The design now known as the selburose has a long history. It appears in textiles across European history, and in knitting pattern books from Italy, France, Switzerland and Germany in the 16th to 18th century. It appears to combine designs of Islamic and Christian tradition based on Coptic and Byzantine art, or even the Sumerian Star of Ishtar.
