Magnes gave his name to the people of Magnesia. He was a son of Zeus and Thyia (or else Aeolus and Enarete, or even Argus and Perimele), and was the father by a Naiad of Polydectes and Dictys. Most probably, his name actually evolved out of the name Magnesia, which was a place rich in minerals and also gave its name to 'the Magnesian stone', otherwise the 'magnet'.
