The Stymphalian Birds

The noise above the lake

Heracles raises the bronze clappers on a mountain above Lake Stymphalus and sounds them over the trees. The deep wood below suddenly releases its countless birds. Once they rise into the open, he can use his bow. In Apollodorus’s account, an order to chase them away has reached its decisive moment, but only after Heracles has failed to bring the birds within reach.

Until that noise, the shelter has defeated him. The birds have gathered in the wood around the lake after fleeing from wolves, and Heracles cannot get them out. Athena gives him the clappers she received from Hephaestus. The labour therefore depends first on an instrument and the fear it creates: Heracles can shoot only when the birds abandon the cover that kept them safe.

Why driving them away was enough

Eurystheus does not initially command Heracles to kill the birds. Apollodorus says that he orders the hero to chase them away. The difference matters because the task begins as a problem of removal. The birds have made the lake and its surrounding wood their refuge, while Heracles must turn that refuge against them without being able to enter it effectively.

The danger also changes between accounts. Apollodorus calls the flock countless and explains why it has gathered, but does not call the birds man-eaters. Pausanias records that description as the story told around Stymphalus. The man-eating detail belongs to the local account he heard, not to a description shared by every version.

In Apollodorus, noise reaches where Heracles cannot and forces the concealed threat into movement. Pausanias gives no single sequence. His accounts disagree about what Heracles does to the birds.

Whether Heracles shot the birds

The ending in Apollodorus has two stages. Heracles frightens the birds from the wood with the clappers, then shoots them as they fly up. Expulsion and killing belong to the same sequence in that account.

Pausanias sets two endings beside one another instead. One says that Heracles shoots the birds. The poet Peisander says that he drives them away with rattles and does no more. A flock struck by arrows and a flock leaving the lake are not the same result, even if both satisfy the command to remove it. The labour has no single settled finish.

That disagreement changes the meaning of the bronze instrument. In one version it exposes targets; in another, its sound is itself the victory. Heracles may need the bow, or he may need only enough noise to make the birds depart.

What remained at Stymphalus

The birds also belong to the local religious landscape, not only to Eurystheus’s labour. Pausanias records an old sanctuary of Artemis Stymphalia, with a wooden image of the goddess that was mostly gilded. Near the roof were carved birds. Behind the image stood maidens of white marble whose legs were shaped like those of birds.

Pausanias does not turn these elements into a single explanation of the flock. The roof carvings recall birds, while the marble figures combine a woman’s form with avian legs. They show how closely the creatures remained attached to Artemis and Stymphalus without deciding whether Heracles killed them or drove them elsewhere.

How the birds reached Olympia

The labour also entered the sculpted sequence of the Temple of Zeus at Olympia. The Greek Ministry dates the temple to around 476-457 BC. It describes the sculpted decoration as Parian marble and says that the Labours of Heracles unfold on the metopes. Pausanias later names the Stymphalian Birds among those panels.

The Louvre dates the surviving metope to about 460 BC. It is incomplete, consisting of three original fragments: Athena seated, Heracles’s head and his right arm. The fragments were found at the Temple of Zeus in 1829 and are now displayed at the Louvre. What survives makes Athena physically present in the scene, as she is in Apollodorus’s account, but it cannot establish which written ending the sculptors followed.

Metal once completed parts of the relief. The Parian marble retains attachment traces for a diadem and for birds, additions that have not survived with the three fragments. The birds are absent, but the fixing marks for their metal forms remain on the marble found at Olympia.
