Hera (Juno) Goddess of Marriage

Juno is an asteroid and in our birth chart she fosters and sustains union with a partner. More generally, she symbolises the principle of relatedness and commitment to another over time. She signifies reaching out from the Self to another in order to complete oneself in a one-to-one relationship.

In the Olympian pantheon of classical Greek Mythology, Hera, was the wife and older sister of Zeus. Her chief function was as goddess of marriage. Her equivalent in Roman mythology was Juno. The cow and later the peacock were sacred to her.

Hera was born of Cronus and Rhea, and was almost swallowed but stopped due to a prophecy. Because of this, she broke the prophecy that one of Cronus's children would take over his throne.

Zeus was not swallowed because of a plan hatched by Rhea and Gaea. Rhea wrapped a stone in baby clothes and gave that to Cronus. Zeus was then moved to a cave on Crete. Rhea later gave Kronus a herb which she told him could make him completely invincible.

The herb actually made him regurgitate the five other Olympians: Hestia, Demeter, Hera, Hades, and Poseidon, as well as the previously ingested stone. When Zeus grew older, he banished Cronus to Tartarus, the deepest chasm in the underworld, because the Titans were immortal and could not be killed.

Portrayed as majestic and solemn, often enthroned and crowned with the polos, the high cylindrical crown worn by several of the Great goddesses, Hera may bear in her hand the pomegranate, emblem of fertile blood and death and a substitute for the narcotic capsule of the opium poppy.

Hera was well-known for her jealous and vengeful nature, most notably against Zeus's paramours or their offspring, but also against other mortals who crossed her, such as Pelias or arguably even Paris, who had offended her by choosing Aphrodite as the most beautiful of goddesses, and thus earned Hera's hatred.
