Pronunciation

  • Classical: [beːs.tiˈaː.ri.ʊs][1]
  • Ecclesiastical: [bes.tiˈaː.ri.us][1]

Forms

bēstiārius m (genitive bēstiāriī or bēstiārī); second declension[1] As an adjective: bēstiārius, bēstiāria, bēstiārium; first/second-declension adjective.[1][2]

Etymology

It is from Latin bēstia (“beast”) + -ārius.[2][1][3] The origin of bēstia is uncertain; de Vaan compares bēlua (“beast, monster”).[4]

Earliest recorded meaning

Cicero is the first author.[3][5] In the Pro Sestio he mocks an aedileship that offered “one lion, two hundred beast-fighters”, ūnus leō, ducentī bēstiāriī.[3]

Semantic evolution

It named a man who fought wild beasts in the arena;[2][6] Georges and Lewis and Short distinguish hired fighters, who were armed and rewarded when they won, from condemned criminals, who fought without weapons.[7][6] Both give Ancient Greek θηριομάχης (thēriomákhēs) as its equivalent.[7][6] Seneca tells of a lion in the amphitheatre that recognised one of the beast-fighters as its former keeper and protected him,[3] and Petronius has a speaker who has seen better beast-fighters.[3] As an adjective it is found only in Seneca's in lūdō bēstiāriō, a beast fight, a reading the TLL marks as doubtful.[3][8][7]

In Christian writers the old Latin text of 1 Corinthians, quoted by Tertullian, says that God chose the apostles as if they were bēstiāriī, where the Vulgate has “as men condemned to death”,[3] and Lactantius complains of making beast-fighters rich.[3] Glossaries explain it as a hunter of beasts.[9][10] British Medieval Latin used the adjective for beastlike or savage, the neuter as a noun for cattle, and the word for a book of beasts, a bestiary.[10]
