Juga
Or Jugalis, that is, the goddess of marriage, occurs as a surname of Juno, in the same sense as the Greek Zygia. She had a temple under this name in the forum at Rome, below the capitol, and the street which there took its commencement was called vicus Jugarius. (Augustine's De Civitate Dei; Festus, p. 104, ed. Müller.)
