The original Coptic cross has its origin in the Coptic ankh symbol and was adopted by early Christian Gnostics such as the well known Valentinus of Alexandria, Egypt. The Coptic cross of today, used by Coptic Orthodox Christians, has many different forms. The circle represents the eternal and everlasting love of God. Christ's halo was commonly depicted with cross-based halo in the early and especially the eastern parts of Christianity. The full cross symbolizes Christs crucifixion and resurrection.
