Thebes, Herakles labors - The Wild Birds of Stymphalus

The Wild Birds of Stymphalus, amphora 530 BC

In the sixth labor, Herakles was ordered to destroy the voracious birds, who had been brought by Ares at the lake of Stymphalus, in Arcadia. These man eating birds had claws, wings and beaks of brass and their feathers could be shot like arrows.
Herakles with the help of Athena, who provided him with a pair of brazen rattles (krotala) making loud noise, frighten them away and shot them with his arrows, killing many of them. The majority was driven away to the island of Aretias, in the black sea, where they were found by the Argonauts, who also frightened away from there, after a hard fight.
