Did You Know?

Ancient mariners noted that all the stars in the heavens seem to revolve around a particular star, and they relied on it to guide their navigation. The constellation that this bright star appears in is known to English speakers today as Ursa Minor, or the Little Dipper, but the Ancient Greeks called it Kynosoura, a term that comes from a phrase meaning "dog's tail." Kynosoura passed into Latin and Middle French, becoming cynosure. When English speakers adopted the term in the mid-16th century, they used it as a name for the constellation and the star (which is also known as the North Star) and also to identify a guide of any kind. By the early 17th century, cynosure was also being used figuratively for anything or anyone that, like the North Star, was the focus of attention or observation.

Origin and Etymology of cynosure

Middle French & Latin; Middle French, Ursa Minor, guide, from Latin cynosura Ursa Minor, from Greek kynosoura, from kynos oura, literally, dog's tail

First Known Use: 1565
