In Greek mythology, Iynx (Greek: Ἴϋγξ, translit. Íÿnx) was an Arcadian Oread nymph; a daughter of the god Pan and Echo. In popular myth, she used an enchantment to cast a spell on Zeus which caused him to fall in love with Io. In consequence of this, Hera metamorphosed her into the bird called iynx (Eurasian wryneck, Jynx torquilla).
Iynx was an Arcadian nymph and the daughter of Pan and Echo, or Peitho. She was the creator of a magical love-charm known as the iynx—a spinning wheel with a wryneck bird attached. Iynx used her enchantments to make Zeus fall in love with her or with the nymph Io. Hera was enraged and transformed her into a wryneck bird.
According to another story, she was a daughter of Pierus, and as she and her sisters had presumed to enter into a musical contest with the Muses, she was changed into the bird iynx. This bird, the symbol of passionate and restless love, was given by Aphrodite to Jason, who, by turning it round and pronouncing certain magic words, excited the love of Medea.
