What kind of time-scale with regards to Rome? Because afaik Italy went from what they call the pre-Roman era, to the Roman escalation towards empire, then rapidly became Xian under the still-existing emperors of the early Xian era.
So, if you want pre-Roman stuff, that’s probably traceable through archaeological/historical sites & books, if you want Roman, that should be pretty easy to come by, and Xian era is probably a mix of Mediterranean syncretism (buts of Gnostic, Hellenic, Egyptian, Jewish and maybe even Vedic thought) plus a heavy dose of Roman, and Orthodax (then later, Catholic) folk-magick using saints and Xian ideas.
Google stuff like “Italian superstition” and “Italian curse,” and add in terms like “birth,” “death,” “baby,” “fertility,” “marriage” “good luck” etc for those. Any area where people commonly like to use magick, even just as an old superstition.
