Polydōrus
（Πολύδωρος).
1.
Son of Cadmus and Harmonia, father of Labdacus, and great-grandfather of Oedipus.
2.
Youngest son of Priam and of Laothoë; his father's favourite son. He was killed while yet a boy by Achilles. The tragedians make him the son of Priam and Hecuba, who, before the fall of Troy, committed him with many treasures to the care of their guest-friend, the Thracian king Polymestor (or Polymnestor). After the capture of Troy, Polymestor put the boy to death, in order to get possession of the gold, and threw the body into the sea. The waves cast it up on the Trojan shore, and here Hecuba found it, just as Polyxena was on the point of being sacrificed. Out of revenge she, with the help of the captive Trojan woman, killed the two children of the murderer and blinded Polymestor himself. According to another version, Ilioné, Priam's daughter and Polymestor's wife, brought up the brother, who had been committed to her charge, as her own son, while she gave up her child Deïphilus (or Deïpilus) instead of Polydorus. The Greeks, who wished to exterminate the race of Priam, won over Polymestor by promising him the hand of Electra and a large present of money in return for the murder of Polydorus. Polymestor then murdered his own son, and was blinded and killed by Ilioné.
3.
A Greek sculptor of the school of Rhodes, author (in conjunction with Agesander and Athenodorus) of the celebrated group of Laocoön (q.v.).
