Hercules’ sixth task was straightforward: Travel to the town of Stymphalos and drive away the huge flock of carnivorous birds that had taken up residence in its trees. This time, it was the goddess Athena who came to the hero’s aid: She gave him a pair of magical bronze krotala, or noisemakers, forged by the god Hephaistos. Hercules used these tools to frighten the birds away.
