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.
Middleworld In ancient Maya cosmology, Middleworld is the Earth, or the world of men. "In ancient Maya thought, the universe was suffused with sacredness that resonated from the presence of deities. The ancestors, spirits and deities not only resided in the Upperworld and the Underworld (sometimes called Xibalba), but also shared the Middleworld, or Earth with its human and animal populations." All three were joined by the World Tree, a giant ceiba tree which served as the central pole holding the worlds together. The nine levels of the Underworld were represented by the roots, Middleworld by the trunk, and the thirteen heavens of the Skyworld by the branches. This concept is similar to the beliefs held by many ancient cultures, including the Norse, who thought that they inhabited a middle-earth. The Maya also believed that their pyramid temples were sites at which these worlds could be transversed. Maya kings, by undergoing ritual and trance, could open portals which would allow the gods - inhabitants of the sky and under worlds, to communicate with Middleworld.
