Marsyas

Marsyas, a Phrygian satyr, who, having found a flute that played of itself, which Athena had thrown away, was rash enough to challenge Apollo to a musical contest, subject to the condition that the victor should do what he liked to the vanquished. Apollo played upon the cithara, Marsyas upon the flute, and the Muses decided in favour of the god, who punished his rival's temerity by binding him to a tree and flaying him alive. From his blood sprung the river Marsyas; his statue stood in many ancient cities, a monument of the folly of presumption.
