Ultimate origin
Proto-Indo-European (*diu-bʰeh₂-es-)

Pronunciation

  • Classical: [ˈjʊ.bar][1]
  • Ecclesiastical: [ˈjuː.bar][1]

Forms

iubar n (genitive iubaris); third declension[1] Ennius and the Aetna treat it as masculine.[2][3] Ennius once has iubār.[4]

Etymology

De Vaan, following Dunkel's analysis, traces it to Proto-Italic *dju-faos and Proto-Indo-European *diu-bʰeh₂-es- (“having or bringing the light of daytime”), a compound of the word for sky or day with the root of shining, first an epithet of some neuter noun.[4] He compares Sanskrit भास् (bhā́s-, “light, radiance”) and Ancient Greek φαίνω (phaínō, “to shine, reveal”).[4] The OLD calls the origin doubtful and the TLL uncertain;[2][5] Lewis & Short and Köbler connect it with iuba “mane”,[3][6] and ancient writers derived it from the mane or from Jupiter.[5]

Earliest recorded meaning

De Vaan dates it from Ennius,[4] in whom someone asks whether the light seen in the sky is the dawn.[2]

Semantic evolution

It is first the light of dawn: Pacuvius has the rising of the morning light, and Virgil chosen young men leaving the gates at sunrise.[2] More generally it is the radiance of heavenly bodies or of fire: Lucretius has the sun's trembling light under the earth, and Ovid the morning star raising its bright light from the sea.[2][3] Festus explains it as the star the Greeks call Phosphorus or Hesperus.[3] Concretely it is a source of light: in Ovid a soul is to be made into a star.[2][3] Figuratively it is splendour or glory, as Martial's radiance pouring from Caesar's face.[3] Church Latin glosses it radiance, beaming light.[7]
