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.
Altar An altar is any structure upon which offerings such as sacrifices are made for religious purposes, and by extension the 'Holy table' of post-reformation Anglican churches. Altars are usually found at shrines, and they can be located in temples, churches and other places of worship. Today they are used particularly in Christianity, Buddhism, Hinduism, Shinto, Taoism, as well as in Freemasonry. Also seen in Neopaganism and Ceremonial Magic. Judaism used such a structure until the destruction of the Second Temple. Many historical faiths also made use of them, including Greek and Norse religion.
