A survey, a text, some scanty response and examplifications were produced, but since then not much has happened and the project has inadvertently been put to rest.
For my part, one of the examples from this discussion was later epitomized visually and will be presented here, along with the mythological interpretation.
Clint Eastwood's early western movies predestined him for incarnating the archetype of The Hanged Man in cinema; someone who by capitulating to the cyclical processes has attained a calm, wise and vacuous personality, fit for the audience´s inflated projections.
Furthermore, I think that this mysterious non-human element goes hand in hand with his morphological appearance, which could be described as lying somewhere between root crop and old wood (a derivative relative of his is the ironic comics super-hero Flaming Carrot, whose name and character even further juxtaposes the very same traits).
So, what is individualized in Clint Eastwood´s figure in this image I´d call - and here I borrow a phrase from the speculative sphere of natural philosophy - something like "the impacts of vegetal intelligence on human life." Part human, part plant he is depicted here as the both mythologically and medicinally complex Mandragora officinarum.
