Forms

prīmipīlāris m (genitive prīmipīlāris); third declension[1][2] Also spelled prīmōpīlāris.[1][2][3] A form prīmipīlārius is found in late inscriptions and law codes; the grammarian Probus condemns it.[3]

Etymology

It is from Latin prīmipīlus (“senior centurion of a legion”) + -āris.[1][3] prīmipīlus is formed from prīmus (“first”) and pīlus2 (“a division of the triarii”),[1][2] a word made from pīlum (“javelin”).[1][4]

Earliest recorded meaning

The TLL finds it often in inscriptions from the age of Augustus on, and more rarely in authors from Seneca the philosopher, Quintilian and Frontinus on.[3] Seneca uses it as a noun, of the senior centurion: cessit primipilari, “he gave way to a senior centurion”.[2][5]

Semantic evolution

In the early Empire it is the centurion of the first century of the first cohort, the senior centurion of a legion,[1] and also a former senior centurion, as in Quintilian's primipilaris senex, “an old ex-senior-centurion”.[2][6] In the army of the later Empire it is an officer in charge of supplies, a commissary, in the Digest and the Theodosian Code,[6][2] and as an adjective it means belonging to such an officer.[6] Sidonius Apollinaris uses it figuratively of a bishop.[2][6][7] It passed into Greek.[3] Medieval writers in Britain use it of a senior commander who leads troops into battle and, figuratively, of a champion of the church who carries the banner of faith.[8]
