Nice to see something about MesoAmerican gods!
I like how Quetzalcoatl/Kukulkan is sometimes represented as a Viking with scale and beard, makes you think there could have been "Vinland" in the Gulf of Mexico too.
The article makes no mention of this and since Vikings didn’t have a monopoly on beards or scales, I don’t think your statement earned the matter-of-fact-edness with which you delivered it.
