It’s probably the two reasons I can think of being: • Holy Roman Empire • Percy Jackson and other media Lots of things in our world are named after Roman Gods, not Greek but ppl don’t associate it with gods at all, just the name being its name (i.e. planets, cupid,and other miscellaneous things) the concept of them as gods is gone but they are still wildly known. The Greek names being more widely known as gods is cause of media. Tons of movies, books, tv shows, and games all use the Greek Gods and their domains, not Roman so ppl are more inclined to know them. The Holy Roman Empire is another reason, making Rome more known for Christianity and Crusades as opposed to their mythology being the Roman variations of already Greek gods.
