Stymphalus
A lake and region in Arcadia where Heracles defeated the man-eating Stymphalian Birds as his sixth labour
The Story of Stymphalus
Stymphalus was a lake and surrounding district in the mountainous interior of Arcadia in the Peloponnese. The lake, which periodically drained through sinkholes and refilled — a characteristic of the region's limestone karst geology — was the setting for one of Heracles' most famous labours. A flock of monstrous birds with bronze beaks, sharp metallic feathers they could launch like arrows, and toxic droppings had infested the marshy lake, terrorising the surrounding countryside and poisoning the land. Heracles could not approach them through the dense swamp, so Athena provided him with a bronze rattle (krotala) forged by Hephaestus. The tremendous noise startled the birds into flight, and Heracles shot them down with his bow or, in some versions, drove them permanently from Greece. The surviving birds were said to have fled to the island of Aretias in the Black Sea, where the Argonauts later encountered them. The myth may reflect real efforts by ancient communities to drain the periodically flooding lake and reclaim the surrounding marshland, with the monstrous birds representing the malaria-carrying mosquitoes that infested such environments.
