In Greek mythology, Abderus or Abderos (Ancient Greek: Ἄβδηρος) was a divine hero, reputed by some to be one of Heracles' lovers (eromenoi), and reputedly a son of Hermes by some accounts, and eponym of Abdera, Thrace.
[4] Pindar makes Abderus a son of Poseidon and Thronia,[5] while Photius writes that he was brother of Patroclus,[6] and according to Hellanicus (who considers him the son of Hermes), he was Heracles' lover.
Along with others, he helped Heracles capture the four savage mares of Diomedes the king of the Thracian Bistones.
Heracles overpowered the grooms and drove the Mares of Diomedes into the sea and left them in the care of Abderus.
Heracles founded the city of Abdera near Abderus's tomb, where agones (Greek: ἀγῶνες), athletic games consisting of boxing, pancratium and wrestling were held in his honor (but chariot races were banned in respect of how he died).
