CYNOSURE, the name given by the Greeks and Romans to the constellation of the Little Bear, Ursa Minor. (Lat. cynosura, Gr. Kvvovovpa, from Kvvos, genitive of Kbwv, a dog, and obpa tail.) 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."
