Juno is a goddess, the wife of Jove and therefore queen of the gods. She loves Dido and Carthage, acting as a patron for that city. She also loves the Latin people and Turnus. (In Virgil's day, she was worshipped as the patron goddess of the Roman Empire.) She often sends her messenger, Iris, the goddess of the rainbow, to deal with affairs on earth. Juno is Aeneas's main antagonist throughout the Aeneid. She hates the Trojans for a number of personal, rather petty reasons, including the fact that the Trojans Ganymede and Paris had once offended her pride. She is a wrathful, proud and vicious force, tirelessly harassing Aeneas and the Trojans, even though she knows that she can't ultimately stop them from achieving their fate.
