The Ankh

The Ankh is one of the most recognizable symbols from ancient Egypt, known as "the key of life" or the "cross of life", and dating from the Early Dynastic Period (c. 3150 - 2613 BCE). It is a cross with a loop at the top sometimes ornamented with symbols or decorative flourishes but most often simply a plain gold cross.

It is an Egyptian hieroglyphic symbol for "life" or "breath of life" (`nh = ankh) and, as the Egyptians believed that one's earthly journey was only part of an eternal life, the ankh symbolizes both mortal existence and the afterlife. It is one of the most ancient symbols of ancient Egypt, often seen with the djed and was symbols, carried by a multitude of the Egyptian gods in tomb paintings and inscriptions and worn by Egyptians as an amulet.

The ankh's association with the afterlife made it an especially potent symbol for the Coptic Christians of Egypt in the 4th century CE who took it as their own. This use of the ankh as a symbol of Christ's promise of everlasting life through belief in his sacrifice and resurrection is most probably the origin of the Christian use of the cross as a symbol of faith today. The early Christians of Rome and elsewhere used the fertility symbol of the fish as a sign of their faith. They would not have considered using the image of the cross, a well-known form of execution, any more than someone today would choose to wear an amulet of an electric chair. The ankh cross, already established as a symbol of life, lent itself easily to assimilation into the early Christian faith and continued as that religion's symbol.
