The Greek cross is a symbol that has been used for centuries in various cultures and religions. It is primarily identified as a cross that has four arms of equal length, with each arm extending out to the four cardinal directions. However, there are several other synonyms or related terms that describe this same symbol. Some of these include the crux quadrata, the square cross, the balanced cross, or the true cross. While each of these terms may carry slightly different nuances or cultural associations, they are all essentially referring to the same iconic image of the Greek cross.
