In Greek mythology, Antigone was a Phthian princess, the daughter of King Eurytion of Phthia and the first wife of the hero Peleus. She bore Peleus a daughter, Polydora. When Peleus rejected the advances of Astydameia, wife of King Acastus of Iolcus, Astydameia in revenge sent Antigone a false message accusing Peleus of infidelity, upon which Antigone hanged herself.

I.Etymology
The Greek mythological character of Antigone (Greek: Ἀντιγόνη; pronounced ann-TIG-ə-nee) was a Phthian princess. As in the case of the masculine equivalent Antigonus, the meaning of the name is "worthy of one's parents" or "in place of one's parents."
II.Family
Antigone was the daughter of Eurytion, king of Phthia, and became the wife of Peleus, the son of Aeacus, king of the island of Aegina.
Peleus and Antigone had a daughter, Polydora, who became the mother of Menesthius by the river god Spercheus.
III.Mythology
Peleus was the son of Aeacus, king of the island of Aegina. Peleus and his brother Telamon killed their half-brother Phocus, possibly accidentally. To escape punishment they fled from Aegina. At Phthia, Peleus was purified by Eurytion, king of Phthia, and married Eurytion's daughter, Antigone.
During the hunt for the Calydonian Boar, Peleus accidentally killed Eurytion and fled Phthia. Arriving in Iolcus, Peleus was purified of the murder of Eurytion by Acastus, the king of Iolcus.
Acastus' wife, Astydameia, made amorous advances to Peleus, which he rejected. Bitter, she sent a message to Antigone falsely accusing Peleus of infidelity, whereupon Antigone hanged herself.
