The Equal-Armed Cross is also known as the Square Cross, the Balanced Cross, the Peaceful Cross, Odin’s Cross, the Solar Cross, the Sun Cross, the Cosmic Cross, the the Greek Cross, and the Celtic Cross. It is found in many ancient cultures, predating Christianity. One of the simplest symbols, it represents several things to different cultures. It is often interpreted as representing either the four seasons, four winds, four elements, or some other aspect of physical nature. An equal-armed cross (often within a circle) represents the planet Earth in traditional astrological/astronomical symbols. The cross could also be used to represent the natural union between male and female. The cross also embodies the concept of unification between ethereal and material. It is common for this symbol be worn at the level of the heart so that the wearer is intimate with the 4-fold concept the cross symbolizes which is: self, nature, knowledge, and God.
