Description It is believed that the Djed is a rendering of a human backbone. It represents stability and strength. It was originally associated with Ptah, god of creation, himself being called the 'Noble Djed'. A djed column is often painted on the bottom of coffins, where the backbone of the deceased would lay, this identified the person with the king of the underworld, Osiris. It also acts as a sign of stability for the deceased's journey into the afterlife.
