Well, there are 3 origins for magick in Romania and usually in Europe as a whole: local ancient craft (here, from ancient times, from dacians, thracians, other ancient locals and invading tribes and peoples - a huuuuge number of tribes migrated throughout E. Europe), Indian stuff or Oriental anyways (usually brought by Rromas or not pc known as Gypsies) and even Christian magick, to call it like that (they have divinations using the Bible and many sacred objects, doing all sorts of unchristian rituals, this includes priests).
Edit: this is a simplistic view (my view/what I presented), since each religion, each people, each ethnicity had or still has his own magick and rituals, sometimes shared with others (usually neighbors), thus Europe has a Rich History of Magick, from many Sources, including Ancient Egyptians, Greeks, Romans, Persians, Germanic Tribes, Slavic Tribes, etc.
