[1] Polymestor was the husband of Ilione,[2] the eldest daughter of King Priam and Queen Hecuba of Troy.
Priam sent the child, along with gifts of jewelry and gold, to the court of King Polymestor to keep him away from the fighting.
After Troy fell, Polymestor betrayed Priam and threw Polydorus into the ocean in order to keep the treasures for himself.
Polymestor claims to have been working in the Greeks' interest by killing Polydorus before he could avenge his brothers and father.
Hecuba refutes this claim by stating that the Greeks have no interest in allying with barbarians.
