Who the twelve are, and why the list shifts
The Olympians are the gods who rule from Mount Olympus after Zeus defeats the Titans. The idea of a council of “twelve” is a convention the tradition repeats, but it does not always close on the same names.
The Theoi archive page on the Olympians names twelve: Aphrodite, Apollo, Ares, Artemis, Athena, Demeter, Dionysus, Hephaestus, Hera, Hermes, Poseidon and Zeus. Hestia appears as “sometimes included amongst the Twelve”, in a second rank.
Hades is also a child of Cronus and Rhea, yet he stays off Theoi’s list: his realm is the underworld. That is why this guide works with the twelve above and mentions Hestia and Hades as edge cases.
Domains and symbols in one table
The table below gathers what Theoi records for each god: what they govern and the attributes that show up in art and texts. A single symbol can serve more than one god, like the aegis, carried by both Zeus and Athena.
| God | Domains | Symbols and animals | Roman name |
|---|---|---|---|
| Zeus | Sky, weather, kings, fate, law and order | Lightning bolt, sceptre, throne, eagle, aegis; oak | Jupiter |
| Hera | Marriage, women, sky; queen of the gods | Sceptre; cow, lion, cuckoo, peacock; pomegranate | Juno |
| Poseidon | Sea, earthquakes, horses | Trident; horse, bull, dolphin; pine | Neptune |
| Demeter | Agriculture, grain, bread | Sheaf of grain, cornucopia, torch; pig, snake | Ceres |
| Athena | Wisdom, war, weaving, crafts | Aegis, gorgoneion, shield and spear; owl; olive tree | Minerva |
| Apollo | Music, prophecy, healing, archery | Lyre, bow; laurel; raven, swan | Apollo |
| Artemis | Hunting, wild animals, children | Bow and arrows; deer, bear | Diana |
| Ares | War, courage, battle-lust | Helm, shield, spear; serpent | Mars |
| Aphrodite | Love, beauty, procreation | Dove, apple, scallop shell, mirror; myrtle, rose | Venus |
| Hephaestus | Fire, smiths, metalworking | Hammer and tongs; donkey | Vulcan |
| Hermes | Messengers, travellers, trade, herds | Caduceus, winged boots, traveller’s hat; ram, hare | Mercury |
| Dionysus | Wine, festivity, ritual madness | Thyrsus, cup, grapevine, ivy; panther | Liber (Bacchus) |
| Hestia (sometimes) | Hearth and home | Kettle; pig; chaste-tree | Vesta |
Notice the patterns: Athena, Ares and Artemis carry weapons, Hephaestus and Hermes carry tools of craft and travel, Dionysus and Demeter bring cultivated plants. The symbol usually tells you at a glance what the god does.
The family tree, from Cronus to Zeus
According to Hesiod’s Theogony, Rhea bore Cronus six children: Hestia, Demeter, Hera, Hades, Poseidon and Zeus. Cronus feared being overthrown by a son and swallowed each child at birth.
When Zeus was born, Rhea hid him in Crete and handed Cronus a swaddled stone. Cronus swallowed it, later vomited it up, and Zeus freed his siblings.
- Generation 1Uranus and Gaia
Cronus mutilates Uranus and throws the parts into the sea. From the foam that forms, Hesiod has Aphrodite rise.
- Generation 2Cronus and Rhea
Six children swallowed one by one: Hestia, Demeter, Hera, Hades, Poseidon and, finally, the stone in Zeus’s place.
- Generation 3Zeus takes power
With his siblings freed, Zeus comes to rule and unites with several goddesses, from whom most of the younger Olympians are born.
Zeus’s children, according to Hesiod, come from different unions. With Metis, whom he swallowed before the birth, Zeus brings forth Athena from his own head; with Leto, Apollo and Artemis; with Maia, Hermes; with the mortal Semele, Dionysus.
With his sister Hera, Zeus has Hebe, Ares and Eileithyia. Hephaestus is a case apart: Hesiod says Hera bore him alone, in anger at Zeus.
Children of Cronus and Rhea
- Zeus, Hera, Poseidon, Demeter, Hestia
- Hades, who stays off the list of twelve
Children of Zeus
- Athena (Metis), Apollo and Artemis (Leto)
- Hermes (Maia), Dionysus (Semele)
Children of Hera
- Ares, with Zeus
- Hephaestus, borne by her alone in the Theogony
Where the sources disagree
Greek mythology is not a single book. It is poems, hymns and accounts from different eras and cities, and each tells the story with variations that the Theoi archive records side by side.
The most famous case is Aphrodite. In the Theogony she rises from sea foam; Theoi’s summary also records the version in which she is the daughter of Zeus and Dione. That is why you find both genealogies in different books.
Why Hestia or Dionysus?
The council has twelve seats, but tradition argues over who fills the last. Theoi gives the seat to Dionysus and classes Hestia as sometimes included. Choosing one of the two is each author’s decision, not a fixed fact.
Hephaestus and Ares: what changes?
In the Theogony, Ares is a son of Zeus and Hera, and Hephaestus is a son of Hera alone. When reading a modern summary, check whether it follows the Theogony or blends traditions, because Hephaestus’s parentage changes from text to text.
From gods to archetypes
Today it is common to read the gods as personality types: the strategist, the leader, the artist, the rebel. It is a modern reading, useful as a mirror for thinking about how you act, and not a doctrine the ancient Greeks taught.
So treat the result of any test like this as entertainment and self-reflection. The Greek god archetype quiz uses the domains in this table as a starting point, without claiming to be a psychological instrument.

Frequently asked questions
Which are the 12 Olympian gods?
Is Hades an Olympian god?
Which Olympians are children of Zeus?
What is the Roman equivalent of each Greek god?
Is Aphrodite a daughter of Zeus or born of the sea?
The twelve Olympians are a convention, not a closed list: Theoi gives the last throne to Dionysus and treats Hestia as an occasional guest. By the Theogony, the elders are children of Cronus and Rhea, the younger ones come from Zeus and Hera, and Aphrodite’s origin varies the most. Use the table as a map of domains and symbols and the quiz as a game of self-reflection.
