Formation
Inherited
First attested
234–149 BC, Cato
Inherited from
Proto-Italic *ferktom

Pronunciation

  • Classical: [ˈfɛr.tũː][1]
  • Ecclesiastical: [ˈfɛr.tum][1]

Forms

fertum n (genitive fertī); second declension[1] The older spelling ferctum is found in Cato and in the Acts of the Arval Brothers; manuscripts of Festus' epitome have firctum.[2][3]

Etymology

The origin is uncertain.[4][2] The TLL compares the adjective Oscan fertalis.[2] Wiktionary's explanation is that it is inherited from Proto-Italic *ferktom, ultimately from Proto-Indo-European *bʰer- (“to roast, bake”), and so related to frīgō (“to roast, fry”);[1] Köbler also refers it to that root.[5] De Vaan, discussing that verb, notes that it cannot be matched with Ancient Greek φρύγω (phrúgō, “to roast”) by regular sound laws.[6]

Ancient grammarians derived it from ferō (“to bring”), because the cake was often brought to sacrifices.[2]

Earliest recorded meaning

It first appears in Cato's treatise on agriculture, where the cake is offered to Jupiter with a prayer that he be honoured by it.[2][7]

Semantic evolution

It was usually paired with struēs, another sacrificial cake:[4] Fabius Pictor, quoted by Gellius, says a box with struēs and fertum had to stand by the bed of the Flamen Dialis,[2] and the Acts of the Arval Brothers record expiations made with struibus fertīsque.[2][3] Persius speaks of trying to win over the god with entrails and a rich cake (opīmō vincere fertō).[2][8] Georges describes it as made of barley meal with oil and honey.[3]

Isidore explains it as an offering brought to the altar, from which he derives the name offertōrium,[2] and medieval glossaries repeat this.[9]

Timeline

  • 234–149 BC – Cato gives a prayer offering the cake to Jupiter.[2][5]
  • 34–62 AD – Persius speaks of winning over the god with a rich cake.[2][5]
  • AD 105 – The Acts of the Arval Brothers record an expiation with struēs and ferta.[2]
  • c. 560–636 AD – Isidore calls it an offering at the altar.[2][5]
  • 8th century – Paul the Deacon's epitome of Festus describes it as a kind of sacrificial cake.[5][2]
