Pronunciation

  • Ecclesiastical: [deˈtɛk.t͡si.o][1]

Forms

dētēctiō f (genitive dētēctiōnis); third declension[1]

Etymology

It is from Latin dētegō (“to uncover”) + -tiō.[2][1]

Earliest recorded meaning

Its first certain use is in Tertullian's Against Marcion (4.36), where Jesus is said to have come down ad detectionem creatoris, “to reveal the Creator”.[3][4][5] Köbler dates Tertullian to about 160–220 AD.[6] Conte also cites it from Seneca the Elder's Controversiae, but only as a conjecture.[7]

Semantic evolution

In the Latin Irenaeus it means the exposure of heretics, paired with convictio “refutation”, and the Passion of Peter and Paul uses it of the unmasking of Simon.[4] Donatus has it in his summary of Terence's Andria.[8]

Medieval writers kept the senses “disclosure, revelation, exposure”;[9] Hildegard of Bingen uses it of a sinner revealing the wounds of his heart to God.[9] In British Latin it also meant the removal of tiles from a roof, the unveiling of the cross on Good Friday, an apocalypse (detectio caeli) and a geographical discovery.[10] English detection first meant “accusation”, in the early 15th century.[11]

Timeline

  • c. 160–220 AD – Tertullian uses it of the revealing of the Creator.[3][4][6]
  • 1298 – A Hungarian charter speaks of the fuller disclosure of the truth.[12]
  • early 15th century – English borrows it as detection, first meaning an accusation.[11]
  • 1508 – A Polish church court record uses it of disclosing a penitent's identity.[13]
