AHC: No end of Greco-Roman polytheism

[Night Gaul]

Your challenge is to have Greco-Roman polytheism survive as a relatively major religion to the modern day. I'd like the POD to be after the death of Constantine the Great, but that's not required. Traditional Greco-Roman religion doesn't necessarily have to be dominant or the majority in any country, it just has to survive and stay relatively prominent.

Unless you have Christianity butterflied away this is going to be hard.

Maybe Julian doesn’t mess up during his campaign in Mesopotamia. Or doesn’t attack at all. He was the last pagan ruler of Rome iirc, and while I doubt he could get rid of Christianity perhaps he could ensure its survival somehow?
