Pronunciation

  • Classical: [ˈtʰa.ɫa.mʊs][1]
  • Ecclesiastical: [ˈtaː.la.mus][1]

Forms

thalamus m (genitive thalamī); second declension[1] A Greek form thalamos is also used.[2]

Etymology

It is borrowed from Ancient Greek θάλαμος (thálamos, “inner room, bedroom”), especially in its Homeric use.[2][1][3] Etymonline relates the Greek word to θαλάμη (thalámē, “den, lair”) and θόλος (thólos, “vaulted building”);[4][5] Köbler gives a root ⟨*dʰel-⟩ “vault, hollow” (Pokorny 245).[4][5]

Earliest recorded meaning

Catullus, in a wedding song: uxor in thalamō tibi est, “your wife is in the bridal chamber”.[2] Köbler records it from Virgil on.[5]

Semantic evolution

A poetic word, thalamus is an inner chamber, especially for sleeping: Virgil's Cyrene hears a cry thalamō sub fluminis altī, in her chamber beneath the deep river.[2][3] Vitruvius uses it technically for a room of the Greek house.[2] Above all it is the room and bed of a married couple, and so marriage itself: Dido wishes she had lived thalamī expertem, “without marriage”.[2][1] Pliny uses it of the twin shrines of Apis.[2]

Church Latin glosses it “bedroom, bridal chamber, couch, platform”.[6] Köbler records medieval forms such as talamus and a medieval sense “state treasury”.[5] English took thalamus from Modern Latin in botany in 1753, for the receptacle of a flower.[4]
