The Djed is thought to be a representation of a human backbone. It is a symbol of power and stability. It was originally linked to Ptah, the creation god. He is known as the “Noble Djed.” As the Osiris cults grew in popularity, it became known as Osiris’ backbone. A djed column is frequently painted on the bottom of coffins, where the deceased’s backbone would lie, to identify the dead with Osiris, the king of the underworld. It also serves as a sign of steadiness for the deceased’s afterlife journey.
