Metrodorus of Cos
Metrodorus of Cos was the son of Epicharmus. Like several of his family he addicted himself partly to the study of Pythagorean philosophy, partly to the science of medicine. He wrote a treatise upon the works of Epicharmus, in which, on the authority of Epicharmus and Pythagoras himself, he maintained that the Doric was the proper dialect of the Orphic hymns.
