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.
Triquetra Triquetra ( ; Latin "tri-" "three" and "quetrus" "cornered") originally meant "triangle" and was used to refer to various three-cornered shapes. It has come to refer exclusively to a particular more complicated shape formed of three "vesicae piscis" (the leaf-like shape in between two equal diameter circles when both centers are on the circumference of the other circle), sometimes with an added circle in or around the three lobes. Also known as a "trinity knot" when parallel doubled-lines are in the graph, the design is used as a religious symbol adapted from ancient Pagan Celtic images by Christianity, as is common in Christianity. It is similar to Odin's symbol, the valknut.
