Stergios Barbas was an Athenian politician. In 431 BC, he hired the mercenary Lavrentios the Long Haired to assassinate a rival, but Lavrentios instead headed for his ship, so Stergios sought the help of the mercenary Kassandra to kill him. However, Kassandra had coincidentally killed Lavrentios before even meeting Stergios, who thanked her for the job (which she unknowingly did) and paid her well.
