Pronunciation

  • Classical: [arˈkaː.ri.ʊs][1]
  • Ecclesiastical: [arˈkaː.ri.us][1]

Forms

arcārius (feminine arcāria, neuter arcārium); first/second-declension adjective[1]

Etymology

It is from Latin arca (“chest, money-box”) + -ārius.[2][3][4] The noun is the adjective used substantively.[2]

Earliest recorded meaning

The adjective first appears in Gaius' Institutes, on debts called arcaria nomina, which in his words create no obligation but are evidence of one already made.[5][6]

Semantic evolution

As a noun it meant a treasurer or cashier;[2][6] inscriptions also spell it ark-.[2] The Vulgate uses it of treasurers in Esther and of the treasurer of a city in Romans, and it appears in the Digest;[3] Lampridius uses it of a controller of public revenues.[3]

In medieval Latin it remained the word for a treasurer,[4][7] of a royal palace in a letter of Alcuin of 796,[8] and of the Roman curia and other churches.[9] The MLW also records it for a carpenter who makes chests, in Albertus Magnus.[9]

Timeline

  • 140–180 AD – Gaius speaks of arcaria nomina.[5][10]
  • 390–406 AD – The Vulgate uses the noun for treasurers.[3][10]
  • 533 AD – The Digest has the noun.[3][10]
