Pronunciation

  • Classical: [aˈkʷɪ.lɪ.fɛr][1]
  • Ecclesiastical: [aˈkʷiː.li.fer][1]

Forms

aquilifer m (genitive aquiliferī); second declension[1]

Etymology

It is from Latin aquila (“eagle”) + -fer (“bearing”),[2][1][3] literally “eagle-bearer”.[4] The second element belongs to ferō (“to carry”),[1][5] which goes back to Proto-Indo-European *bʰer- (“to carry”).[6][1]

Earliest recorded meaning

It is first found in Caesar,[5][7] who in the Gallic War writes of the aquilifer Petrosidius throwing the eagle (aquilam proiecit).[7][4]

Semantic evolution

The word always named the officer who carried the eagle, the chief standard of a Roman legion.[2][4][1] Caesar uses it again in the Civil War, and it recurs in Valerius Maximus, Suetonius, Tacitus and in inscriptions.[4][7] Vegetius defines the aquiliferi as “those who carry the eagle”.[7]

Timeline

  • c. 50 BC – Caesar names the standard-bearer of a legion aquilifer.[7][4][5]
  • c. 75–c. 150 AD – Suetonius uses it.[4][7][5]
  • 98–115 AD – Tacitus uses it in the Histories.[7][5]
  • c. 400 AD – Vegetius explains the title in his manual of the art of war.[7][5]
