Pronunciation

  • IPA (Classical): [zoːˈdi.a.kʊs][1]
  • IPA (Ecclesiastical): [d͡zoˈdiː.a.kus][1]

Forms

zōdiacus (feminine zōdiaca, neuter zōdiacum); first/second-declension adjective[1]

Etymology

It is borrowed from Ancient Greek ζῳδιακός (zōidiakós, “of the signs”), with κύκλος (kúklos, “circle”) understood,[1][2] from ζῴδιον (zṓidion, “small figure; sign of the zodiac”), a diminutive of ζῷον (zôion, “animal”).[3] The native Latin term was orbis signifer, the sign-bearing circle.[4][5]

Earliest recorded meaning

Cicero uses it in his translation of Aratus.[4][6] Köbler dates Cicero 81–43 BC.[7]

Semantic evolution

It was the zodiac, as a noun or with orbis or circulus, the circle of the twelve signs through which the sun passes.[2][6] Gellius uses it, and Censorinus says the Greeks call the signifer the zodiac.[4][5] As an adjective, of the zodiac, it appears in Sidonius and Martianus Capella.[4][6] Isidore describes the zodiac circle in his chapters on astronomy.[8]

Medieval writers used it of the belt of the heavens centred on the sun's path.[9] English zodiac is recorded in the late 14th century.[3]
