But there is an image of four Was holding up the four corners of the sky/roof, showing that it could have the quality of strength as you suggest and also definitely not being used for weaving. This said, the image is interesting because it includes the top part and the forked bottom ends which would have no use whatsoever as pillars or even decoration – so it seems more a statement about the owner of the loom and her power than about the tool in itself. You can probably tell that I still think it's the original spinnekrok!
The acts of spinning and weaving fit in with many subjects, from mummies to fine clothes to fishing nets. It’s my contention that all kinds of images from Mesopotamia, Egypt and elsewhere are to be seen through the eyes of a weaver. It must have been a prestigious craft, imitating the Matriarchal figure’s own work on the cosmic loom. As for the baboon, perhaps it’s too much of a stretch to go from the Was to Thoth, to Thoth as baboon, and then the jar. That doesn’t directly link the Was to either the baboon form, the jar, or the lung. But I won’t rule it out. Need to find the baboon somewhere with the tool.
I don’t think the string connection is strange at all…and look forward to any pictures or extra stuff on the subject that you might come across.
