Thank you Ritva,
My understanding is that there were two phases of creation, the first or the beginning forced by Nun which created the two realms, am I wrong to associate Akeru with this first phase? In the second phase Ptah creates Re by digging a tunnel between the two realms which allowed Re to be re-born every day, it is my assumption that Aker guards the entrances for Ptah's creation and then Geb is featured as the earth god. I associated Aker via Ptah's creation of Re. The confusing part is when we try to understand Khnum as an equivalent creator god that is contemporary with Ptah, hence my belief that Akeru and Aker concepts belong or trend toward lower Egypt as opposed to upper from whence Khnum belongs. All said it seems more that geographical locations played less of a role or point of origin; Khnum-Khufu built at Giza.
I have a few questions; archaic/pre-dynastic era - was there a god represented by an eel? and was Nun ever represented in human form?
Best Regards,
