Marsyas
Note from The Dialogue Of Apollodorus by Plato

The Satyrs were also connected with Dionysus, and were beings with goat-like characteristics addicted to every kind of sensuality. Marsyas, one of their number, to whom, as well as to Silenus and Olympus, the invention of the flute was ascribed, challenged Apollo to a trial of skill in flute-playing, and on being defeated was flayed alive.
