Pronunciation

  • Classical: [ˈae̯.re.ʊs][1]
  • Ecclesiastical: [ˈɛː.re.us][1]

Forms

aereus (feminine aerea, neuter aereum); first/second-declension adjective[1] In Virgil the form aereī is scanned as two syllables.[2][3]

Etymology

It is from Latin aes (“copper, bronze”) + -eus.[2][1][3]

Earliest recorded meaning

Its first example is in Varro's Menippean Satires, which speak of an aerea galea, a bronze helmet.[2][4]

Semantic evolution

Virgil has bronze thresholds and a bronze sword, and uses it too of things bound or armoured with bronze: a wheel with a bronze rim in the Georgics and a ship's bronze-clad stern in the Aeneid.[2][5] Germanicus applied it to the human race of the bronze age.[2]

From the metal it passed to what bronze produces: Laberius has a bronze gleam, and Statius the clamour and crash of bronze instruments.[2][3] Pliny the Elder uses it for the colour of copper, of the bristles of wild pigs and of a cloudy stone with copper-coloured veins.[2][3] As a noun, aereus was a copper coin.[2]

Ecclesiastical Latin keeps the sense “of copper, bronze or brass”,[6] while Niermeyer records a medieval sense “sky blue”.[7]
