Cynosura (nymph)

In Greek mythology, Cynosura (Κυνοσούρα κυνός οὐρά, ) is the name of an Idaean Oread nymph from the island Crete who brought up a young Zeus during his early years when he hid from his father Cronus, and ended up among the stars.

Mythology
Along with fellow nymph Helice, Cynosura put the infant Zeus in a cave and nurtured him in Ida, in Crete, while the Dictaean Curetes deceived Cronus so he would not devour his son. One day, Cronus happened to visit Crete, so Zeus hid the nymphs by transforming them both into bears, as he changed his shape into that of a dragon, in order to go undetected by Cronus. Eventually, after he became king of the gods, he honoured his two nurses by placing them both in the sky as constellations, and Cynosura became Ursa Minor, which was a common name for the constellation in Ancient Greece. The most common origin myth for the two bear constellations, however, was that of Callisto, a follower of Artemis, and her son Arcas.

The origin of the word "Cynosura"/"dog's tail" is unknown, as it does not connect to the theme of the constellation, and no other constellation fitting the description exists. It has been argued that the derivation from the word for dog is false.
