This is a statue of Marsyas (of the Zagreb type), Roman, second century AD, found in Perge in 1981 in the Gallery of Claudius Peison (to whom it is dedicated) at the South Bath.

Athena had a flute, but playing it distorted her face, so she threw it away. Marsyas, who taught playing this instrument, picked it up and played it so well the gods decided not even Apollo could play this well. Marsyas should have contradicted them, but did not, angering Apollo who proposed a match. That ended undecided until Apollo put his lyre on its head and began to play and sing, a feat Marsyas could not reproduce. So he lost and under the rules he had agreed with at the start Apollo chose his punishment. He was flayed alive, hung on a tree and beheaded. Other versions of the ending, some a bit less gruesome, exist. His flute hangs to his right, he wears a lion skin (paws crossed round his neck), and in his left arm has his own skin.
Found in 16 pieces it is generally agree to be from the early 3rd century BC, during the first Hellenistic period.
