I guess I'm looking for myth that promotes communal ideas, relates to worker alienation, etc.? I think of the book of Acts in the bible, that's somewhere between an example of how christians are supposed to live and a defense of paul before he's executed, right? but incidentally the book has ideas that can be carried forward and developed into a marxist-friendly understanding of how to live, even if it's loaded in stuff a well read marxist would find objectionable, there will be no perfect examples and i find it tiresome to get lost in pedantry about it so spare me!!!
I also wanna write some. Like "hades began to push and proliferate communism because he was horrified by the trauma of the humans coming through his gates and despised our cruel fates" feels like a decent basis for a mythic story idk
look i dont wanna get into the relationship of myth and religion to marxism, not really, i just like writing fake myth and i need an idea of what's out there in order to make something worthy of the concept
I would argue that myths and stories are written by the wealthy class of people, hence I won't expect anything that will undermine the interest of that class. I think denying education to workers or children of workers was a common tactic to suppress workers.
Myths almost always involve kings and other figures of power. So as you vaguely mentioned most of the time it's the villains of the story that may hold a "progressive" view, but there is always a twist to make them look bad.
From your post I understand that you are not necessarily looking for existing stories, but you also want to write. Maybe trying to work out how a common person may experience the events in a myth will give some ideas.
Do post if you write anything. I'm really interested to read.
