Interesting.

I think this is a better link.

I don’t know anything about any of this other than the 2 minutes I just spent reading wikipedia.

My guess would be that Griaule overlaid a contemporary understanding of astronomy on top of their mythology, either through ineptitude or as a way to procure funding for more expeditions.

What I mean is, it’s infinitely more likely that their mythology was “we are the descendants of the brightest star we can see”, than they are actually descended from refugees from sirius.
