Iuno Iuga: an altar in the Vicus Iugarius (q.v.) from which Festus (Paulus ex Fest. 92L) believed the vicus derived its name. This Juno was supposed to matrimonia iungere. Because the Vicus Iugarius was certainly very old and probably derived its name quite differently, the altar is apt to have received its name from the vicus, rather than vice versa, a punning invention from Juno's role as patroness of marriage, but the form Iuga is puzzling. There is no telling exactly where it was situated, but presumably it was adjacent to neither the Forum Romanum nor the Porta Carmentalis.
