Hi J!
I'm new here - so excited to be in community with others!
I've been interested delving in this too - making the effort to understand who my ancestors were beneath layers of colonization. Just yesterday I got a book all about ancient indigenous spiritual Practices in the Philippines. It's so cool and MIND BLOWING to see the connections - there's even stuff in there about how modern mystics believe that the Islands of the Philippines were once part of Lemuria!
I don't know much about the history of Syria or the Middle East, but have you tried searching in the context of "decolonized" knowledge or specific indigenous groups/history? I'm not sure if this applies in that context but this is the wording I've been using to find the information I'm looking for.
