The pentacle is a five-pointed star, or pentagram, contained within a circle. The five points of the star represent the four classical elements, along with a fifth element, which is typically either Spirit or Self, depending on your tradition. The pentacle is probably the best-known symbol of Wicca today, and is often used in jewelry and other designs. Typically, a pentacle is traced in the air during Wiccan rituals, and in some traditions it is used as a designation of degree. It is also considered a symbol of protection, and is used in warding in some Pagan traditions.
