The ankh was the Egyptian hieroglyphic character that egyptologists read as "life,". Egyptian gods are often portrayed carrying it by its loop, or bearing one in each hand with their arms crossed over their chest. Additionally, an ankh was often carried by Egyptians as an amulet, either alone, or in connection with two other hieroglyphs that mean "strength" and "health". Mirrors of beaten metal were also often made in the shape of an ankh, either for decorative reasons or to symbolize a perceived view into another world. It is also known as the Egyptian Cross, the key of life, the key of the Nile, or as crux ansata, Latin for "cross with a handle".
The ankh has come to symbolise life and immortality, the universe, power and life-giving air and water. Its key-like shape has also encouraged the belief it could unlock the gates of death, and it is viewed this way by the modern Rosicrucians and other hermetic orders. The Coptic Christians have used it as a symbol of life after death.
It can also be seen to represent the male triad and the female unit, under a decent form.
