Pronunciation

  • Classical: [kʊ.bɪ.kʊˈɫaː.ri.ʊs][1]
  • Ecclesiastical: [ku.bi.kuˈlaː.ri.us][1]

Forms

cubiculārius (feminine cubiculāria, neuter cubiculārium); first/second-declension adjective[1] Inscriptions also have cubuculārius and the syncopated cubīclārius and cubūclārius.[2] The genitive plural cubiculāris in Suetonius is a variant reading.[3]

Etymology

It is from Latin cubiculum + -ārius,[4][1] from cubiculum (“bedroom”), itself from cubō (“to lie down”).[1][5]

Earliest recorded meaning

Cicero is the first to use it, as a noun for the servant who looked after his master's bedroom: in the Verrines he tells his opponents that their bedroom servants are fond of a certain man.[3][2][5]

Semantic evolution

As an adjective it meant “of the bedroom”: Martial uses it in the titles of epigrams, one on a bedroom lamp, and Pliny the Elder uses it of bed covers.[3] Suetonius names the chief of the emperor's bedchamber staff decurio cubiculariōrum.[3][2] In Late Latin the bedchamber servants of the imperial court were officials;[6] Ammianus Marcellinus speaks of those set over the duties of the bedchamber,[6] and Jordanes has the feminine for a chambermaid.[7]

In the Church it meant a private chamberlain,[8] and in medieval courts the cubicularius was one of the officers of the prince's household; at the French court he ranked below the chamberlain in chief.[9]
