Forms

praefurnium n (genitive praefurniī or praefurnī); second declension[1][2]

Etymology

It is from Latin prae- (“in front”) + furnus (“oven”) + -ium.[1][3][4] De Vaan lists it among the derivatives of fornus, which he takes to be the original form, with ⟨furn-⟩ spreading in part of Roman speech; he traces it to Proto-Italic *χworno- and Proto-Indo-European *gʷʰr-no- (“heat; oven”).[5] Cognates include Old Irish gorn (“fire”) and Sanskrit घृण (ghr̥ṇá-, “heat, glow”).[5]

Earliest recorded meaning

It first appears in Cato's De agri cultura, in the instructions for a lime kiln: si uno praefurnio coques (“if you burn with one stoke-hole”).[2][3] He also warns that the wind must not reach the furnace mouth.[3]

Semantic evolution

Vitruvius uses it for the furnace room that heats a bath, called Ancient Greek προπνιγεῖον (propnigeîon),[2][6][3] and for the mouth of a small furnace for making lampblack, which is closed so that the flame does not escape.[3]

Timeline

  • 234–149 BC – Cato uses it of the stoke-hole of a lime kiln.[3][4]
  • c. 84–c. 25 BC – Vitruvius uses it of the furnace of a bath.[3][2][4]
