The Ankh is a combination of two Sumerian symbols: ME, the spirit, and HI, the passageway, giving its name or one of them to be Mehi, the passage of the spirit on its journey to enlightenment. There’s a very interesting Old Syrian seal in the Met which mixes iconography of Mesopotamia and Egypt, although they don’t make any case of it in their blurb which is thoroughly Egyptian. (Accession Number:1991.368.5) Is Syria a disregarded link?
The ibis holds a tool in its right hand where the Djed is signified as four strokes across the rod of the Was. We already discussed djed shortly with Thanos as resembling Sumerian NUN. NUN has the main meaning of the otherworld. Here the four stripes represent the four ways of the heavens, the four noble truths of Buddhism leading to enlightenment. Taoism and Buddhism permeate the Sumerian texts and come from much older sources than commonly thought. Here they are represented as obstacles across the rod, to be overcome on the journey. The rod, spiralling or straight, is the path up which slide the snakes (and the spun fibres) between the earth and the sky. I daresay someone will point out the djed with a different number – the NUN too - but this is not a thesis, just a jogging down of the thoughts after reading you and others here.
The needle’s eye, more clearly seen at the base of the identical but spiralling djam, represents the difficulty to begin this journey, and has come down to us as the parable of the rich man. The forked element on other instruments has the meaning of the two ways, duality, the two cords of the womb (discussed on the AoM). Both are also to be found in the twisted or fused tails of the two great lions in quite a lot of Egyptian images.
In Sumerian iconography, there exists a cylinder seal with a single seated dog who has a similar needle eye in the middle of its tail. I would surmise that the Sumerian equivalent is the symbol KUN, the tail of the dog (verified by ePSD and by me in a proverb) but also the weir, built to regulate the passage of the flow, and so a line that divides but always comes back together eventually. A picture of KUN is quite difficult to find in the earliest version, but it appears to be a vertical line rising out of a net, perhaps a piece of woven material, and the head is just a line across but possibly the same angle as the spinnekrok.
The head of the Was is, as you say, a head. It’s the head of the dog/wolf, but a cosmic animal since this is a cosmic and spiritual story. I would guess that it’s Sirius. So in my version there is no body or spine, only the forked tail up and down which glide the serpents or the earthly energies. I’ll take it one step further since I’m already treading on dangerous waters with you all here…the rod of the was is also the combined tails of the two Great Lions of Giza, regulators of the waters and of the spiritual journey. None of this negates my original theory of the overall form of the was being that of the spinnekrok, but the Weaver is a particularly great one!
Despite appearances, I have respect for all of your theories. This is just one to add to the pile of loose threads. Everything always comes back to the warp, the loom, and the weaving of the cosmic fabric. Just my opinion.
