Aren’t Ifa, Santeria, and Voudoun different currents of the same river?
I was under the impression they were, more-or-less, regional varieties of the same faith. Weren’t a significant portion of the slaves sent to the Americas of West African origin?
According to what I’ve gathered, and please tell me if I’m wrong, Baron Samedi=Papa Legba=Ellegua=Eshu (depends on what you want him for), and the rest don’t seem to change too too much - just the spelling of the names. Some of the orishas do seem to have different parts of their natures emphasized in the differing religions, though. I’m not sure if Oya’s owning the cemetaries is mentioned much, or at all, where Baron Samedi’s role is emphasized, f’rinstance.
Purely from written sources and not enough of them, I’d hazard a guess that the Ifan religion recognizes many more orishas than the other two - one source theorized that some of the less popular sects didn’t have enough believers on the other side of the pond to be self-sustaining.
I was also under the impression that Santeria was originally primarily Brazilian, and Voudoun was primarily Haitian and in the southern States.
Cites. uhhhh. Bell, Book, and Candle by I forget who, Santeria by some professor or another, in conjunction with a believer, African Religious Philosophy by what’s his pickle, a bunch of different West African mythology texts (well, okay, folktales), and a handful of other, similar books whose titles and authors completely escape me…
To brutally wrench around to the subject of the OP, though…I don’t think there’s much like that extant anymore. The old Inuit religion was pretty scary, and there was a whole lot of placating a hostile nature and even more hostile shamans, but it’s been pretty much replaced by a type of Christianity.
I think the closest to what you’re looking for, historically, would be Zoroastrian followers of Ahura Mazda, and even then, I don’t beleive there were enough of them to count as the leaders of the faith.
Oh wait.
One of my Asian mythology books (basically a laundry list with precious few details other than “cotton shirt: wash with starch”, or " Umai: Turkic fertility goddess") suggest that you might find what you’re looking for among the Yakuts of Siberia. Details are pretty thin - but the reference is to “Ulu Toyo’n, the malevolent creator spirit”.
