Marsyas Flayed by the Order of Apollo by Charles André van Loo 1735

"[Athena] threw away the pipes [she had invented] and vowed that whoever picked them up should be punished severly. Marsyas, a shepherd, son of Oeagrus, one of the Satyri, found them, and by practicing assiduously kept making sweeter sounds day by day, so that he challenged Apollo to play the lyre in a contest with him. When Apollo came there, they took the Musae (Muses) as judges. Marsyas was departing as victor, when Apollo turned his lyre upside down, and played the same tune--a thing which Marsyas couldn't do with the pipes. And so Apollo defeated Marsyas, bound him to a tree, and turned him over to a Scythian who stripped his skin off him limb by limb. He gave the rest of his body for burial to his pupil Olympus. From his blood the river Marsyas took its name."

-Pseudo-Hyginus, Fabulae 165 (trans. Grant) (2nd C. CE)
