Pronunciation

  • Classical: [ky.nɔˈsuː.ra][1]
  • Ecclesiastical: [t͡ʃi.noˈs̬uː.ra][1]

Forms

Cynosūra f sg (genitive Cynosūrae); first declension[1]

Etymology

It is borrowed from Ancient Greek κυνόσουρα (kunósoura, “dog's tail”),[2][3][1] from κύων (kúōn, “dog”) and οὐρά (ourá, “tail”).[4][5]

Earliest recorded meaning

Cicero uses it in his translation of Aratus: ex his altera apud Graios Cynosura vocatur, altera dicitur esse Helice, “of these, one is called Cynosura among the Greeks, the other is said to be Helice”.[6] It is the constellation of the Lesser Bear.[2][3]

Semantic evolution

The constellation was the sailor's guide: Ovid contrasts the Phoenicians, who steer by Cynosura, with the Greek ships, which watch Helice,[2] and Lucan says no star led ships more surely.[6] Cicero used it in a figure, saying that he steers his thoughts not by the little Cynosura but by Helice.[2] Hyginus makes Cynosura a nurse of Jupiter, set among the stars,[2][6] and Statius uses it for a place in Arcadia.[3][7][6] The adjective is Cynosūris.[3]

Medieval writers kept it for the Lesser Bear or the pole star.[8][9] From it French and English took cynosure, “something that draws attention”.[5]
