Kinship

How are Hades and Persephone related?

Uncle and niece, twice over: Hades is the brother of both of Persephone’s parents, Zeus and Demeter, all three children of Cronus and Rhea.

Hades is a son of Cronus and Rhea — in Hesiod’s order the first-born son, swallowed by his father and freed along with his siblings. Persephone sits a generation lower, and her line reaches the same couple by two paths: through her father Zeus and through her mother Demeter. Because her parents are themselves brother and sister, her two sets of grandparents are one and the same pair. Hades is therefore doubly her uncle, her father’s brother and her mother’s brother at once, and the diagram climbs from her to Cronus and Rhea twice. One generation further up, the same closeness makes them first cousins once removed through Gaia and Uranus.

The oldest full telling of their story, the Homeric Hymn to Demeter, turns on that kinship. Zeus has already granted his daughter to Hades, knowing Demeter would refuse, and Hades carries her off while she is picking flowers. When the grieving mother learns what has happened, Helios offers a strange comfort: the abductor is her own brother, of the same parents, who rules a third of the world — a match she need not be ashamed of. Hesiod’s Theogony, by contrast, gives the abduction only a passing mention.

The archive wires the familiar parentage — Zeus and Demeter — which the Homeric Hymn and Hesiod share. Other traditions tell it differently. The Orphic Rhapsodic Theogony makes Persephone the child of Zeus and his own mother Rhea, who afterwards becomes Demeter; in that version Hades and his queen would share a mother. Some sources, casting her as a power of death, give her the river Styx for a mother. Under any of these accounts she remains Zeus’s daughter, so Hades is at the least her father’s brother.
