What is an "ankh"?

An ankh is an ancient Egyptian hieroglyphic symbol that represents the concept of life, both physical and eternal. The symbol resembles a cross with a loop on top and is believed to have originated in the pre-dynastic period of Egyptian history. It is often seen in the hands of deities in ancient Egyptian art and was used as an amulet for protection and as a symbol of power and strength. The ankh was closely associated with the gods Osiris and Isis, and it was believed to be a key to the afterlife, granting the wearer eternal life and immortality. Today, the ankh remains a popular symbol in Egyptian and African culture and is often used in jewelry, tattoos, and other forms of art.
