Here is what I think can be the Djed pillar that is referenced to in the Edfu building texts and the Emerald tablets:
There are two sources that tell about the Djed pillar in relation to a flood that destroyed a part of Atlantis.
The first are the Edfu building texts in the temple of Horus.
The Edfu building texts tell the story of refugee priests coming from a far land that was destroyed by a flood. It also mentions that the only object that survived this flood was the Djed pillar. It apparently does not seem to describe what this Djed pillar was.
But the fact that the Djed pillar was the only surviving object that they were aware of when they fled from their homeland, is a match with the fallen pillar that seems to be near the Richat structure.
The other source are the Emerald tables. These tell about the Temple of light. It could be the same structure.
In tablet 1 of the Emerald tablets [8] there are some phrases that match with this idea.
“Downward into the darkness turned the thoughts of the Atlanteans, Until at last in this wrath arose from his AGWANTI, the Dweller, (this word has no English equivalent;
it means a state of detachment) speaking The Word, calling the power.
Deep in Earth's heart, the sons of Amenti heard, and hearing, directing the changing of the flower of fire that burns eternally, changing and shifting, using the LOGOS, until that great fire changed its direction.
Over the world then broke the great waters, drowning and sinking, changing Earth's balance until only the Temple of Light was left standing on the great mountain on UNDAL still rising out of the water; some there were who were living, saved from the rush of the fountains.”
These tablets also tell the story of refugee priests going to the land of Khem.
