Pronunciation

  • Classical: [ˈmʊɫk.trũː][1]
  • Ecclesiastical: [ˈmulk.trum][1]

Forms

mulctrum n (genitive mulctrī); second declension[1] Manuscripts also spell it with ⟨ltr⟩, ⟨lcr⟩ or ⟨lchr⟩.[2]

Etymology

It is formed from Latin mulgeō (“to milk”) + -trum, with the suffix of instrument nouns.[3][1] De Vaan, who treats it with the feminine mulctra, finds that it was not built on the present stem of the verb but continues an older formation from the root.[4] The verb goes back to Proto-Italic *molgeje- and Proto-Indo-European *h₂mlǵ-eie- (“to milk”).[4]

Earliest recorded meaning

Horace (65–8 BC)[5] has the plural in the Epodes: illic iniussae veniunt ad mulctra capellae, “there the she-goats come to the milking pails unbidden”.[6]

Semantic evolution

The word kept its single meaning, a milking pail.[3][6] The TLL finds the neuter plural mulctra only in poetry, from Horace on (Calpurnius Siculus, Valerius Flaccus, Nemesianus, Prudentius), and the neuter singular only in Isidore of Seville.[2]

Timeline

  • 65–8 BC – Horace uses the plural mulctra for milking pails.[6][5]
  • 1st century AD – Calpurnius Siculus uses it in his eclogues.[6][5]
  • end of 1st century AD – Valerius Flaccus uses it.[6][5]
  • 348/49–c. 413 AD – Prudentius uses it in a hymn.[6][5]
  • c. 560–636 AD – Isidore of Seville has the neuter singular.[2][5]
