Cynosure
CYNOSURE (Lat. cynoswra, Gr. Kvvoaovpa, from KVVOS, genitive of KVUV, a dog, and ovpa, tail), the name given by the Greeks and Romans to the constellation of the Little Bear, Ursa Minor; the word is applied in English to the pole-star which appears in that constellation, and hence to something bright which, like a " guiding-star," draws all attention to it, as in Milton's " cynosure of neighbouring eyes."
