Roman Names

Borne by Bacchus, Roman god; Greek counterpart Dionysus

Bacchus is not a native Latin formation at all but a borrowing of the Greek name Bakchos, whose own origin is itself uncertain and possibly non-Greek.

Borne by Jupiter, Roman god; Greek counterpart Zeus

Jupiter comes from an Old Latin vocative compound, Iou pater, "O Father Sky," fusing the same *dyeu- root behind Zeus directly with the word for "father" into a single, permanent name.

Borne by Mars, Roman god; Greek counterpart Ares

Mars, from an older poetic form Mavors, has a genuinely obscure, likely pre-Latin origin that predates any contact with Greek Ares - his name is not a Latin translation of the Greek war god's at all.

Borne by Mercury, Roman god; Greek counterpart Hermes

Mercury's name is transparently Latin, built on merx, "merchandise," and mercari, "to trade" - one of the clearest etymologies among the major Roman gods, and entirely unrelated to the separate, unconnected Greek name Hermes.

Borne by Neptune, Roman god; Greek counterpart Poseidon

Neptune's etymology has no accepted solution: standard Latin scholarship treats Neptunus as genuinely unclear, possibly pre-Latin, with a leading but unproven guess connecting it to an ancient word for moisture or cloud.

Borne by Pluto, Roman god; Greek counterpart Hades

Pluto is the Latinized form of the Greek Plouton, built on ploutos, "wealth," a deliberate euphemism that recast the lord of the dead as the giver of the earth's buried riches.

Borne by Vulcan, Roman god; Greek counterpart Hephaestus

Vulcan, from Latin Volcanus, has no accepted Latin or wider Indo-European derivation and is generally treated as a pre-Latin word, possibly of Etruscan background, naming one of Rome's oldest and most distinctly Italic gods.

Borne by Ceres, Roman goddess; Greek counterpart Demeter

Ceres descends from a Proto-Italic word meaning "with grain" or "of nourishment," making her name one of the most transparently agricultural of all Roman divine names.

Borne by Diana, Roman goddess; Greek counterpart Artemis

Diana descends from an Old Latin form, Dīvāna or Diwjana, built on dius/divus, "divine, shining" - putting her, at a distance, in the same ancient *dyeu- word family as Jupiter and Zeus.

Borne by Juno, Roman goddess; Greek counterpart Hera

Juno's etymology is genuinely disputed: the leading modern theory ties it to iuvenis, "young," and a shared Indo-European root for vital force, though ancient Romans themselves connected it instead to iuvare, "to help."

Borne by Minerva, Roman goddess; Greek counterpart Athena

Minerva's name likely descends from an Old Latin form, Menerva, built on a Proto-Italic root for "intelligence" - but the goddess reached Rome partly through Etruscan Menrva, which complicates calling her name purely Latin.

Borne by Venus, Roman goddess; Greek counterpart Aphrodite

Venus was an ordinary Latin common noun, "charm" or "sexual attractiveness," long before it named a goddess - the abstract quality was named first, and the goddess was named after it, not the reverse.
