Note that "up" is consistently in the north west. I have a suspicion that the four 45 degrees rotated poles are reflected in the hieroglyph 𓊖 for the four city quarters (urbis & orbis). since they are not anchored on the pole star, they might just represent idealized points of sunrise / sunset yet being aware of the pole star or at least the symmetry.

I believe that 9,000 years ago there wasn’t as distinct a pole star due to axial procession. Celestial north would probably have been somewhere between Vega and Tau Hercluis with a fairly wide separation.

There would have been circumpolar stars though, and those would have been very noticeable.
