The divine consort, or the principle of relatedness. Juno (Hera), the wife of Jupiter (Zeus, the Lord of the Gods) governs wifely relationships, the role of woman as covenanter and partner. In this way she governs such things as contracts and binding agreements, through her association with marriage. Juno's rule was overthrown by the victory of Jupiter, which introduced the custom of marriage and a patriarchial social system. Juno can be fierce and is bound by a sense of duty and social obligation. Her dark side also rules such things as divorce, and separation, infidelity and open conflict between partners. "Astrologically Juno describes the ways in which we face the issues of compatibility, receptivity to others, mutual sharing, trust, jealousy, possessiveness and power struggles."
