Rhea is a Titan in Greek mythology, daughter of Gaia and Uranus, sister and wife of Cronus, and mother of six major Olympian gods: Hestia, Demeter, Hera, Hades, Poseidon and Zeus. Her family tree links the primordial gods of Hesiod’s Theogony to the generation that rules Mount Olympus.
Rhea’s place in Greek mythology
Rhea belongs to the Titans, the divine generation between the primordial beings and the Olympians. Her parents, Gaia (Earth) and Uranus (Sky), are among the earliest powers in Hesiod’s account of the cosmos. Rhea and Cronus are two of their children. The Titans are therefore Rhea’s generation, while the Olympians are chiefly her children’s generation.
Rhea is associated with motherhood and the continuity of divine rule. Ancient Greek sources do not present every detail of her identity in exactly the same way, and later traditions sometimes connect or identify her with other mother goddesses. The central genealogy, however, is clear in Hesiod: she is the mother of the six siblings who become prominent among the Olympians.
Rhea family tree
- Parents: Gaia and Uranus.
- Siblings: Rhea’s siblings include the Titans Oceanus, Coeus, Crius, Hyperion, Iapetus and Theia, Themis, Mnemosyne, Phoebe and Tethys. Hesiod also names the youngest Titan, Cronus.
- Spouse: Cronus, Rhea’s brother and fellow Titan.
- Children: Hestia, Demeter, Hera, Hades, Poseidon and Zeus.
- Grandchildren: Through her children, Rhea’s descendants include many gods and heroes. Examples include Persephone, daughter of Demeter; Ares, Hebe and Eileithyia, children of Zeus and Hera; and Athena, Zeus’s daughter in the usual account.
Genealogies of the gods can branch differently across myths, especially in accounts of parentage and divine partnerships. The list above gives Rhea’s standard immediate family in Hesiod’s Theogony; it is not a complete catalogue of all figures later connected to her descendants.
Cronus and the swallowed children
Rhea’s best-known story explains how Zeus escaped being swallowed by Cronus. In Hesiod’s Theogony, Cronus fears that one of his children will overthrow him, as he had overthrown Uranus. He swallows each child as it is born. Rhea cannot prevent the first five from being taken, but when Zeus is born she hides him and gives Cronus a stone wrapped in swaddling clothes. Cronus swallows the stone, believing it to be the newborn.
Rhea’s parents help arrange Zeus’s concealment in Hesiod’s account. When Zeus grows up, he makes Cronus disgorge the swallowed children; the siblings then join him in the conflict against the Titans. The precise events and supporting characters vary in later retellings, but the central point is consistent: Rhea’s deception preserves Zeus and enables the next divine generation to challenge Cronus.
A common misconception is that Rhea swallowed or rescued all six children herself. In the standard story, Cronus swallows Hestia, Demeter, Hera, Hades and Poseidon, while Rhea saves Zeus at birth by substituting the stone. The earlier siblings are eventually freed when Cronus disgorges them.
Rhea’s children and their roles
- Hestia: Goddess of the hearth and domestic fire. She is often described as the eldest daughter of Cronus and Rhea.
- Demeter: Goddess associated with grain and agriculture. Her daughter Persephone is central to myths explaining the seasonal cycle.
- Hera: Queen of the gods and goddess especially associated with marriage and royal authority. She becomes Zeus’s wife.
- Hades: Ruler of the underworld and the dead, alongside whom Persephone reigns.
- Poseidon: God of the sea, earthquakes and horses in Greek myth.
- Zeus: Ruler of the Olympian gods and the youngest son in the familiar birth-and-rescue story.
These six are often grouped as siblings, but their roles and status are not identical. Hades, for example, is a major god but is not usually counted among the twelve Olympians in the same sense as Zeus, Hera or Poseidon. Lists of the Olympians can vary, so “Rhea’s children” and “the twelve Olympians” are not interchangeable categories.
How the genealogy changes across traditions
Hesiod’s Theogony is the clearest early source for Rhea’s immediate family and the succession story. Other Greek authors and later mythographers may emphasize different episodes, add local details or give a figure more than one parentage. Greek mythology is not a single fixed scripture, so a family tree should be read as a map of a prominent version rather than a universal record shared by every ancient community.
Rhea is also sometimes associated with the Phrygian mother goddess Cybele, particularly in later Greek and Roman religious contexts. This association does not mean every account treats them as exactly the same figure. Rhea’s genealogy as the daughter of Gaia and Uranus belongs to Greek myth; the relationship to Cybele reflects cultural identification and religious influence over time.
Frequently Asked Questions
