The exploit of Herakles destroying the Stymphalian Birds was one of his Twelve Labors, and people have assumed that this reverse commemorates that event. However, all actual representations of that labor show him attacking flying birds with arrows or slingbolts, while we have him here striding along with an upraised club, as if chasing running birds! Thus, we need to look for something else. Almost certainly, what we have here is a symbolic representation of the freeing of much of the Peloponnesos from Spartan domination after the battle of Leuctra in 362. The close parallel with the figure of the Athenian tyrant-slayer Harmodios is, thus, by no means coincidental.
