IIRC, I'm pretty sure there's also a lot about that in the Bible too (e.g Israelites worshiping other gods like Baal, people up to and including kings).
I don't know, Aaron himself orchestrating the golden calf seems as close to state-sponsored idolatry as fits in the narrative. (No comment on the rest of the epistemological clustercuss.)
Plus the "not" part is the weakest part of historical study and archaeology. From this time we have about 1 page of text for every 10 years for the entire continent.
