03 · Places of devotion
Abode & sacred sites
Mount Olympus; Dodona, where Homer's Achilles prays to 'Zeus of Dodona' (Iliad 16.233) and Odysseus goes to hear the will of Zeus from the oak (Odyssey 14.327–330); Olympia, with the gold-and-ivory statue by Pheidias described by Pausanias (5.11); Mount Lycaeus in Arcadia, where, Pausanias says, Zeus was reared (8.38.2); and, in Rome, the Capitoline temple of Jupiter Optimus Maximus (Livy 1.55).
04 · Two traditions
Greek & Roman perspectives
The Greek perspective
Hesiod makes Zeus the youngest child of Cronus and Rhea, who overthrows Cronus and the Titans and takes many wives and lovers (Theogony). The Odyssey presents him as the protector of strangers and suppliants.
The Roman perspective
In Livy, the fetial priest swears the treaty between Rome and Alba by calling on Jupiter to hear the terms (1.24). Modern reference works record that consuls swore their oath of office in Jupiter's name and that triumphing generals wore regalia associated with him.
05 · Extensive analysis
A closer reading
Zeus and Jupiter are matched in Greek and Roman sources, and modern scholars derive both from a common Indo-European sky god, *Dyeus. Greek writers tell stories of Zeus's family, his battles and his loves. In Roman writing, Jupiter appears chiefly in public ritual: the Capitoline temple, oaths, treaties and the consuls' vows.

What the sources say
Zeus is attested from the earliest Greek literature. These are the main ancient passages behind this entry, with what each one actually says.
- Hesiod, Theogony lines 453–491
Rhea bears Zeus as the youngest of Cronus's children. Cronus swallows each child at birth because he has learned he will be overcome by his own son. Earth and Heaven send Rhea to Lyctus in Crete; Earth hides the infant in a cave on Mount Aegeum and gives Cronus a great stone wrapped in swaddling clothes, which he swallows in the child's place.

Zeus's unions in order: Metis (swallowed by him, after which Athena is born), Themis (the Horae and the Moirai), Eurynome (the Graces), Demeter (Persephone), Mnemosyne (the Muses), Leto (Apollo and Artemis) and, last, Hera (Hebe, Ares and Eileithyia).

Where the sources differ
- Hesiod places Hera last among Zeus's wives and has her bear Hebe, Ares and Eileithyia (Theogony 921–923). In the same passage he says Hera bore Hephaestus on her own, without Zeus (Theogony 927–929), so Hephaestus's father is not the same in every source.
- Homer makes Aphrodite the daughter of Zeus, with Dione as her mother (Iliad 5.131, 5.348 and 5.370). Hesiod has her rise from the foam around the severed genitals of Uranus (Theogony 188–206), so in Hesiod she is not Zeus's child at all.
07 · Story & deeper insight
Zeus and the overthrow of the Titans
Cronus swallowed his children to prevent a foretold overthrow. Rhea saved the youngest, Zeus, by handing Cronus a wrapped stone and hiding the infant. Once grown, Zeus brought his siblings back into the world and challenged the Titans. Victory depended on alliances: the Cyclopes supplied the thunderbolt, and the Hundred-Handers helped break the older gods' resistance.
The succession story asks how legitimate authority emerges from violence. Zeus differs from Cronus because he distributes honours and incorporates allies, although his later swallowing of Metis shows that fear of replacement survives the change of ruler. Divine order is negotiated as well as enforced.
Jupiter inherited Greek narratives through Roman literature, but Roman worship gave sovereignty a different public setting. Oaths, magistracies and the Capitoline temple made him a protector of collective order. Reading Zeus's family struggle beside Jupiter's civic authority reveals how shared mythology could serve different political communities.
