Martin & all

I feel sure you would be familiar (perhaps not others here) with Andrew Collins and Rodney Hale's
Astronomical Interpretation of Pillar 43

Even though they also presume or investigate an astronomical significance, they arrive at a very different hypothesis.

I wonder if you could comment on why your interpretation is superior and what is wrong with theirs?
They seem to match at least some prominent stars to their suggested pattern.

Also, do you intend to imply that your treatment of the handbag motifs (equinox/ solstice) carries on into later other depictions of such in Mesopotamian culture?

Is the thrust of your premise a claim that GT folk (generally the "public")understood precession significantly enough that they carved the suns position in constellations and constellations generally to record dates or epochs?
