Xenea
A Naiad who fell in love with Daphnis and made him promise never to form a connexion with any other maiden, adding the threat that he should become blind if he violated his vow. For a time the handsome Daphnis resisted all the numerous temptations to which he was exposed, but at last he forgot himself, having been made intoxicated by a princess.
The Naiad accordingly punished him with blindness, or, as others relate, changed him into a stone. Previous to this time he had composed bucolic poetry, and with it delighted Artemis during the chase. According to others, Stesichorus made the fate of Daphnis the theme of his bucolic poetry, which was the earliest of its kind. After having become blind, he invoked his father to help him.
The god. accordingly raised him up to heaven, and caused a well to gush forth on the spot where this happened. The well bore the name of Daphnis, and at it the Sicilians offered an animal sacrifice.
