The most common shape of tree-topper is a common figure in what family of religions?
Tree-topper A tree-topper or treetopper is a decorative ornament placed on the top (or "crown") of a Christmas tree or Hanukkah bush. Tree-toppers can take any form, but the most common shape is that of an Angel (a "Christmas angel"); tree-toppers shaped as stars (representing the "Christmas star" or the Star of David) or finials are also common. Other less common tree-toppers include paper rosettes, ribbon bows, Father Christmases or Santa Clauses, Christian crosses, owls, and sunbursts.
Katsuogi Katsuogi (鰹木, 堅魚木, 勝男木, 葛緒木 ) or Kasoegi (斗木 ) are short, decorative logs found on Japanese and Shinto architecture. They are placed at a right angle along the ridge of roofs, and are usually featured in religious or imperial architecture. "Katsuogi" predate Buddhist influence and is an architectural element endemic to Japan. They are often placed on the roof with "chigi", a forked ornamentation used on Shinto shrines. Today, "katsuogi" and "chigi" are used exclusively on Shinto buildings and can be used to distinguish them from other religious structures, such as Buddhist temples in Japan.
