The Magnetes were an ancient Greek tribe of the Thessalian Magnesia who took part in the Trojan War.

Prothous, son of Teuthredon, led the Magnetes, 
from the region- round Peneus and Mount Pelion,
where leaves are always trembling in the wind. 
With him swift Prothous brought forty black ships.

Homer Iliad 2

Magnesia on the Maeander Octobol, Horseman with spear, bull ready to attack, Text "MAGNETON" and DIONYSIOS DEMETRIOY, 350/300 BC

According to Strabo Magnesia on the Maender was founded by some Thessalian Magnetes who had collected fellow settlers from Crete en route.

Magnetes names after Magnes

Fragment #16 --

Antoninus Liberalis, xxiii:

Battus. Hesiod tells the story in the "Great Eoiae"....

....Magnes was the son of Argus, the son of Phrixus and Perimele, Admetus' daughter, and lived in the region of Thessaly, in the land which men called after him Magnesia. He had a son of remarkable beauty, Hymenaeus. And when Apollo saw the boy, he was seized with love for him, and would not leave the house of Magnes. Then Hermes made designs on Apollo's herd of cattle which were grazing in the same place as the cattle of Admetus. First he cast upon the dogs which were guarding them a stupor and strangles, so that the dogs forgot the cows and lost the power of barking. Then he drove away twelve heifers and a hundred cows never yoked, and the bull who mounted the cows, fastening to the tail of each one brushwood to wipe out the footmarks of the cows.

First, Hesiod made Macedon a brother of Magnes; as we know from inscriptions that the Magnetes spoke the Aeolic dialect of the Greek language, we have a predisposition to suppose that the Macedones spoke the Aeolic dialect. Secondly, Hesiod made Macedon and Magnes first cousins of Hellen's three sons - Dorus, Xouthus, and Aeolus-who were the founders of three dialects of Greek speech, namely Doric, Ionic, and Aeolic. Hesiod would not have recorded this relationship, unless he had believed, probably in the seventh century, that the Macedones were a Greek speaking people. N.G.L. Hammond
