Forms

prōlogus m (genitive prōlogī); second declension[1] Terence scans the first syllable long.[2]

Etymology

It is borrowed from Ancient Greek πρόλογος (prólogos, “prologue”),[2][1][3] from πρό (pró, “before”) and λόγος (lógos, “speech, word”).[3][4] The TLL notes that Latin took it with a long first syllable, probably by association with prōloquor (“to speak out”).[5]

Earliest recorded meaning

Terence (190–159 BC) is the first to use it, of the prologues he wrote for his plays and of the actor who spoke them.[2][3]

Semantic evolution

In Classical Latin it was the introduction to a play, often summing up its plot, and the actor who delivered it;[2][6] Seneca uses it more generally of a preamble, saying that nothing is sillier than a law with a prologue.[2]

Medieval Latin used it for the prologue of a speech or a written work, and especially for Jerome's prologues to the books of the Bible.[7] Neo-Latin drama kept the speaker of the prologue among its characters.[8] English borrowed it in the early 14th century, partly through Old French.[4]

Timeline

  • 190–159 BC – Terence writes of his prologues and of himself not as a prologue-speaker but as an advocate.[2][3]
  • 4 BC–65 AD – Seneca uses it of a preamble to a law.[2][3]
  • early 14th century – Borrowed into English as prologue.[4]
