Looking at later adaptations of the Atef Crown, which differ greatly from the simple versions we have been looking at and which seem to be conveying information about the brain and its three power centres associated with the ‘third eye’, it’s possible that like the Eye of Horus symbol, your regular, everyday ancient Egyptian did not know the deeper significance of the Atef Crown and the information it contained.
Again, I would suggest, that the design and style of the Atef Crown may have originated from information which had been given to the Egyptian priesthood elite by an advanced people.
Perhaps these people – as represented by the predynastic "gods" known as the Neter or Neteru, or the Shemsu Hor ("followers of Horus") or ‘Shining Ones’ and who were said to have invented Kingship – had dictated what the state crown of Osiris should look like, and so they instructed the natives in the design of the crowns and other regalia.
Apart from any symbolical significance they might have held in regard to concepts already understood or had devised themselves, its possible that the predynastic natives had no real idea of the rather technical brain-mapping information which was contained in the designs and would one day be conveyed.
As the authors of Hamlet’s Mill (1969) have demonstrated, myths were indeed used to transmit complex truths and its possible that to preserve knowledge, an intelligent and scientifically-advanced people had decided to intervene in the cultures of people around the world; shaping their cultures and ‘loading’ certain information which would be absorbed in their art, their clothing, their rituals and their folk tales.
In other words, these people depended on uneducated people to accurately and directly transmit the information across millennia and to the 'scientists' of the future.
What they didn’t reckon on was that a great deal of this information – i.e., the more mystical knowledge – would be subject to discrimination; in that what wasn’t understood would be misinterpreted and become corrupted, and what would be understood, would either be ignored, kept secret, covered-up by mundane explanations and also suppressed.
And if we are in any doubt about the scarab beetle Khepri being a symbol for the thalamus and the ‘third eye,’ then we only have to look at the image below.
Khepri is in the same position – between the Eyes of Horus.
The boat or henu barque symbolises ‘astral travel’ or ‘after death’ travel through the Duat (Underworld) and it rides on the waves of the serpent – i.e., waves of energy.
There is more symbolism in this ancient art, and I could go on and on, but my purpose here is to reveal these now obvious correlations.
In the image below, we see a winged Khepri clutching hold of two disks.
Again the imagery is similar to what we see in the Atef Crown, which appears to be based on the underside view of the brain.
The wings would symbolise the opened corpus callosum or even the left and right hemispheres.
