Pronunciation

  • Classical: [friː.ɡɪˈdaː.ri.ʊs][1]
  • Ecclesiastical: [fri.d͡ʒiˈdaː.ri.us][1]

Forms

frīgidārius (feminine frīgidāria, neuter frīgidārium); first/second-declension adjective[1] The syncopated form frīgdārius is required by the metre in Lucilius.[2]

Etymology

It is from Latin frīgida (“cold water”) + -ārius,[3] from frīgidus (“cold”).[2][4] De Vaan lists the noun frīgidārium under frīgus (“cold, frost”),[5] which goes back to Proto-Italic *srīgos- and Proto-Indo-European *sriHǵ-o/es- (“frost, bitter cold”).[5] Cognate with Ancient Greek ῥῖγος (rhîgos, “cold, frost”).[5]

Earliest recorded meaning

De Vaan records the noun from Lucilius on,[5] who speaks of bringing goods into the cold store, mercem in frigdāria ferre.[4][2]

Semantic evolution

As an adjective it means holding or bringing cold water: Vitruvius describes three bronze vessels in a bath, one for hot, one for warm and one for cold water,[2] and Petronius has cisterns of cold water.[4] Pliny the Younger uses cella frīgidāria for the cooling room of the baths,[3][4] and Palladius a cement for cold baths and a pipe for cold water.[2][6]

As a neuter noun, frīgidārium named the cold room of a bath, from Vitruvius on,[4][2] and in Lucilius a cool place for keeping food.[6][2] The Historia Augusta speaks of baths always cooled with snow.[2]
