The ankh is an ancient Egyptian symbol that represents life and immortality. It is often depicted as a cross with a loop or handle at the top. The loop at the top symbolizes eternal life, while the vertical line represents the connection between the earthly realm and the afterlife. The ankh was closely associated with various Egyptian deities and was believed to hold the key to unlocking the gates to the realm of the dead and the eternal journey of the soul. Today, the ankh remains a popular symbol in various cultures, often associated with concepts of life, health, and spiritual energy.
