When the Greek Cross is discovered in ancient cultures prior to Christianity, it is known as the Equal-Armed Cross, also known as the square cross, the balanced cross, and the peaceful cross. The sacred emblem of the equal-armed cross was well-known. It’s commonly said to represent the four seasons, four winds, four elements, or some other feature of physical nature. In traditional astrological-astronomical symbols, the planet Earth is represented by an equal-armed cross (typically within a circle). The cross can also be used to symbolize the natural union of male and female.
