Pronunciation

  • Classical: [ˈpɫʊm.be.ʊs][1]
  • Ecclesiastical: [ˈplum.be.us][1]

Forms

plumbeus (feminine plumbea, neuter plumbeum); first/second-declension adjective[1]

Etymology

It is from Latin plumbum (“lead”) + -eus.[2][3][1] The origin of plumbum is uncertain.[4] De Vaan, following Beekes, rejects a link with Ancient Greek μόλιβδος (mólibdos, “lead”) and sets it rather beside the Celtic word seen in Old Irish lúaide (“lead”); since that cannot account for the Latin form, he thinks the word for lead may be a loan from another language, and mentions a Berber word for lead that may have the same source.[4]

Earliest recorded meaning

De Vaan and Köbler record it from Plautus,[4][5] who uses it figuratively: si quid peccatumst, plumbeas iras gerunt, “if you do wrong, their anger is like lead”.[2]

Semantic evolution

Its first sense is made of lead: Cato has a leaden cauldron and leaden vessels, Lucretius the leaden sling-shot that grows hot in flight, and Tacitus the name of Germanicus engraved on lead tablets.[2] Plautus and Martial speak of base leaden coins, and Pliny the Elder of a leaden colour of the body.[2] Because lead is soft and blunt, Cicero speaks of being killed with a leaden sword and exclaims o plumbeum pugionem!, “what a leaden dagger!”.[2]

From the qualities of lead it came to mean heavy and oppressive, as Horace's leaden south wind; cheap and worthless, as Martial's leaden wine; and dull or stupid, as Terence's asinus plumbeus, Cicero's “we are dull in natural science”, and Suetonius' man with a face of iron and a heart of lead.[2] Prudentius has blows from a scourge weighted with lead.[6]
