Well, no, yes but, and no. Seasons, time units, and correspondences between natural and cultural categories, are archetypal givens, and compulsive gestalt impulses. Cosmology comes with nature, and with perception. The zodiac was never discovered, never improved, never lost, and never found. Various charts do partial justice to conscious, symbolic, and subconscious expressions of archetypal structure.
Gobekli Tepe pillar D43 is not necessarily a zodiac. Evidence for this is in the similar but different Gobekli Tepe grey pillar (see some images in my article on cultural structure, AoM September 2015); the grey pillar contains the identical mindprint structure of visual expression, but using variant attributes (such as different species).
The differences indicate that both pillars were artworks, probably linked by some mythical, spiritual, theological, and socio-political motivations. The culture probably had a zodiac, but every scorpion is not Scorpius. And every Virgo is not a woman.
Every artwork containing images that are also mythical, does not necessarily or primarily illustrate myth. And culture does not evolve, it merely mutates to the dictates of economy, which at Gobekli was diverse (domesticated species and clothing on the pillars indicate sacrifice, finance, trade, prestige, a calendar, etc). The only resource they lacked was numbers, physical multiplication.
Cultural evolution is a conservative assumption. Our ancestors at Gobekli probably believed in it too. And thought themselves thoroughly modern, fashionable, sophisticated, and feared that their numbers may outstrip the capacity of the cold, infertile, and probably salty earth. The same salt that still lies on some undrained areas as in the Andes.
Facts tend to reveal the paradigm of assumptions of their consumers and diffusers. The supposed ‘discovery’ and diffusion of the zodiac is one of those revealing ‘facts’.
I could not find Audrey's post on the supposed Gobekli zodiac. Nor any Gobekli images that reveal which of the variants they had conventionalised into a calendric craft.
