| Stymphalian Birds (stim-FAY-lee-un). Flying creatures with lethal, metallic feathers who infested the Stymphalian marsh in Arcadia. When Heracles had to confront these man-eaters as one of his Labors, he was aided by Athena. The goddess gave him a pair of castanets. With these noisemakers, he caused the birds to take wing. Then he brought them down by the dozens with arrows from his bow. |
