Hero
Abderus
Heracles’ companion killed while guarding the man-eating mares.

Overview
Abderus preserves the human cost of the eighth labour. Heracles leaves the captured mares in his care while confronting their pursuers, but the animals drag the young companion to death. On returning, Heracles buries him and founds Abdera in his name, so the episode’s success does not erase the person lost while the prize was being guarded.
