Greek mythology
Antiope was the queen of the Amazons. When Antiope was abducted by Heracles and delivered to Theseus (king of Athens), the Amazons joined to release her.
The ninth labor of Heracles was to obtain the Girdle of Hippolyte (sister of Antiope), which his father (Ares, the god of war) had given to her. Heracles kidnapped Antiope and demanded the Girdle of Hippolyte as exchange.
