The Etruscans: Rome’s weird next door neighbor. Or at least that’s how the Romans viewed them. In reality, Etruscan society and social norms were greatly misunderstood by the early Romans and by the Greeks of “Magna Græcia” farther to the south. The freedom Etruscan women enjoyed to leave the house at their leisure and to socialize in mixed settings was taken by the Romans to indicate a certain “sexual availability.” That the Etruscans considered baring your breasts to be a sign of good luck and a way to ward off evil probably didn’t do much to dispel Roman misperceptions.
Unlike their hard-partying imperial descendants, Romans living in the early Republic were notoriously prudish and probably not much fun to hang out with. Being a teen in the early Republic would have sucked because the party scene really didn’t start developing until the late 2nd century BC (have you gotten your villa in Campania yet?). Bare breasts and being okay to hang out with girls in public wasn’t really Rome’s thing until they got the self-confidence that comes with Mediterranean hegemony, I guess.
