Proto-Villanovan culture was part of the central European Urnfield culture system, similarity had been noted in particular with the regional groups of Bavaria-Upper Austria[1] and of the middle-Danube;[1][2] however, a derivation from the previous Terramare culture of the Po Valley is also hypothesized.[3][4] Various authors, like Marija Gimbutas, associated this culture with the arrival, or the spread, of the proto-Italics into the Italian peninsula.[1]
