Lovely to hear from you sunbug.
And yes, I did a piece on thresholds last year.
Really interesting what you write about two different mythic forms. Another way to look at it could be myths that reference universal archetypes – or in your words, a universal order – and how they’re expressed culturally – in your words, social orders. So yes, some myths are certainly specific to a place or culture (say the Rainbow Serpent, which is considered one of the most powerful ancestral beings of Aboriginal Australia), but I feel it’s the universal order that all myths are referencing consciously or unconsciously, even if they are born out of a specific social order.
Be well, Kristina.
