Epithet
A fixed descriptive name attached to a god — Zeus "the aegis-holder" and "son of Cronos", Athena "Tritogeneia" and "bright-eyed", Hera "gold-shod", Odin "Valfather" — which in the poems identifies the god as surely as the name, and in Roman cult (Jupiter Stator, Feretrius, Optimus Maximus) names a distinct temple and function.
Why this wins its question: Pairs each epithet with the line that uses it, and separates the poetic formula (Greek, Norse) from the cult title (Roman), which the dictionaries lump together.
Key takeaways
- Greek epic epithets are fixed formulae (aegis-holder, bright-eyed, gold-shod, Earth-Shaker) and sometimes birth-names (Tritogeneia, Theog. 895, 924).
- Odin has dozens (Grimnismol 46–54); "Valfather" is the seeress's address in Voluspo 1.
- Roman cult epithets (Feretrius, Stator, Optimus Maximus) name separate temples and vows — Livy explains each.

Every assertion below is bound to registered sources and carries its own confidence. Weight them; do not treat the page as uniformly authoritative.
Hesiod opens by naming the gods through their epithets: "Zeus the aegis-holder, and queenly Hera of Argos who walks on golden sandals, and the daughter of Zeus the aegis-holder bright-eyed Athena, and Phoebus Apollo, and Artemis who delights in arrows, and Poseidon the earth holder who shakes the earth" (Theog. 11–15); Zeus is also "the son of Cronos" throughout (Theog. 4, 412, 450).
Homer's formulae do the same work: Athena is "daughter of aegis-bearing Zeus" and returns "to the palace of aegis-bearing Zeus" (Il. 1.202, 1.222); Hera is "ox-eyed, queenly Hera" (Il. 8.471); Poseidon "the Shaker of Earth" (Il. 20.13).
Athena's epithet Tritogeneia is hers at birth: Metis was to bear "the maiden bright-eyed Tritogeneia, equal to her father in strength and in wise understanding" (Theog. 895), and "Zeus himself gave birth from his own head to bright-eyed Tritogeneia" (Theog. 924); the Hymn calls her "Pallas Athena … bright-eyed, inventive, unbending of heart, pure virgin, saviour of cities, courageous, Tritogeneia" (HH28 1–4). Hera is "gold-shod Hera" among Rhea's children (Theog. 454) and "goldshod Hera" as Hebe's mother (Theog. 952).
The Norse poems name Odin by epithet more often than by name: the seeress addresses him as "Valfather" (Voluspo 1, 27) and "Heerfather" (Voluspo 30; Grimnismol 19, 25), and Grimnismol lists his names — "Allfather, Valfather, Atrith, Farmatyr: / A single name have I never had" (Grimnismol 46–54). Thor is "Vingthor", "the son of Jorth", "Hlorrithi" and "Sif's mate" within one poem (Thrymskvitha 1, 6, 24).
In Roman cult an epithet is a temple: Romulus vowed the first temple in Rome to Jupiter Feretrius for the spolia opima (Livy 1.10.5–7), vowed another to "Jove the Stayer" (Stator) to halt a rout, and rallied his men with "Jupiter Optimus Maximus bids you stand" (Livy 1.12.4–7). Virgil's Juno is "Saturn's daughter" and "Saturnian Juno" (Aen. 1.23, 1.130; cards 1.12 and 1.124) — a genealogical epithet in the Greek manner.
