Yes, according to Greek mythology, Zeus married both of his sisters, Hera and Demeter, though under very different circumstances:
- Hera: Hera became Zeus’s official wife and queen of the Olympian gods. Their marriage was significant in mythology, but it was famously tumultuous due to Zeus’s many infidelities. Hera was the goddess of marriage and family, which added complexity to their relationship given Zeus’s behavior.
- Demeter: Zeus’s relationship with Demeter was more of a union than a formal marriage. They had a child together, Persephone, who later became the queen of the underworld after her abduction by Hades. This union was not as prominently emphasized in mythological accounts as his marriage to Hera.
Such marriages among siblings were common in Greek mythology and were symbolic rather than reflective of actual practices, representing the divine interconnectedness of the gods.
