Hera.
The daughter of the Titans Cronus and Rhea, Hera was the wife and sister of Zeus (Jupiter) and the mother of Ares (Mars), Eileithyia, Hebe, and Hephaestus (Vulcan). A goddess worshiped in pre-Hellenic times, she was the deity of marriage and women.
She was perhaps the most jealous goddess in the Greek pantheon: Zeus's innumerable affairs were well known to her, so that she frequently occupied herself with taking vengeance on his mistresses, such as Callisto, Leto, Io, and Semele, and on his offspring, including Dionysus (Bacchus) and Heracles.
Hera's nature also prompted her hatred of the Trojans after the Judgment of Paris, in which the Trojan prince favored Aphrodite (Venus) over her and Athena (Minerva). Because of his decision, both Hera and Athena sided with the Greeks in the Trojan War. Hera also harried Aeneas at Troy and throughout his travels.
The wrath of Juno — which Vergil refers to as saevae memorem Iunonis ob iram (Aen.1.4) — is the principal theme in the epic. All characters suffer some degree of hardship because of Juno's mindful wrath.
Hera is often equated with the Roman goddess Juno, an old Italian deity whose sphere of responsibility was closely parallel. Juno presided over women and the sexual aspects of their lives, especially marriage and childbirth. The Matronalia, March 1, celebrated Juno as patron of women; June, her month, was the propitious time for weddings. Unlike Hera, however, Juno gained importance as a goddess of the state and in Roman times was worshiped as 'Juno Regina' (Queen Juno).
The goddess is often depicted with her husband or with other deities, especially her children. Images of her as a benefactress of women are also popular, particularly in allegorical renderings. She is associated with the peacock (an attribute explained in the myth of Io), and is often depicted riding in a chariot drawn by peacocks, sometimes symbolizing the element Air.
