If we organise all the data in a graphic, we can more easily make some reflections for proving that the matter is still too far of being closed. Let’s see what we have about the nwn gesture of shaking hair forwards.
If we just look at the evolution we see that there is no trace of an explicit nwn gesture in the Old Kingdom. It seems that during the Old Kingdom the normal practice for mourners (the common ones and the two representatives of Isis and Nephtys) was to pull the hair (nwn m), not to shake it (nwn). This last one appears in documents from the Middle Kingdom, and the New Kingdom is the most prolific period, mainly in iconography. Does it mean something?
- Was the nwn gesture of shaking hair sm3 forwards developed sometime before the Middle Kingdom; let’s remember that in XI Dynasty it is already entirely developed, as the stele of Abkaou proofs in the Festivity of Osiris.
- Could we think that the nwn gesture was something that belonged just to the Festivity of Osiris? And later on it was included in the funerals of common people?
- Maybe it has been a matter of pure luck and documents have not preserved (or have not been yet discovered) for knowing that the nwn gesture was also made by the two professional mourners in the role of Isis and Nephtys during the Old Kingdom. In fact the Pyramid Texts say they pull their hair sm3, not their frontal lock of hair swt. Could it be a trace of the nwn gesture in the professional mourning ritual at that time?
- On the other hand, the corpus of scenes the artists had for the private tombs of the Old Kingdom did not include images of the funerary ceremony nor of the Opening of the Mouth ceremony. So, the nwn gesture could be made in the mourning ritual of the Old Kingdom, but we cannot see it because it was not represented.
