Mythology
Peleus and his brother Telamon killed their half-brother Phocus, perhaps in a hunting accident and certainly in an unthinking moment, and fled Aegina to escape punishment. In Phthia, Peleus was purified by the city's ruler, Eurytion, and then married the latter's daughter, Antigone, by whom he had a daughter, Polydora. Eurytion received the barest mention among the Argonauts (both Peleus and Telamon joined the Argonauts themselves, "yet not together, nor from one place, for they dwelt far apart and distant from Aigina"). However, Peleus accidentally killed Eurytion during the hunt for the Calydonian boar and fled from Phthia.
Peleus was purified of the murder of Eurytion in Iolcus by Acastus. Acastus's wife, Astydamia (also called Hippolyta or Cretheis), fell in love with Peleus and after he scorned her, she sent a messenger to Antigone to tell her that Peleus was to marry Acastus's daughter. As a result, Antigone hanged herself.
Astydamia then told Acastus that Peleus had tried to rape her. Acastus took Peleus on a hunting trip atop Mount Pelion and once Peleus fell asleep, Acastus hid his sword in cow dung and abandoned him on the mountainside. Peleus woke up and as a group of centaurs was about to attack him, the wise centaur Chiron, or, according to another source, Hermes, returned his sword to him and Peleus managed to escape. Alternatively the gods appreciated his piousness and sent Hephaestus to him, who gave him a sword. He pillaged Iolcus and dismembered Astydamia, then marched his army between the rended limbs. Acastus and Astydamia were dead and the kingdom fell to Jason's son, Thessalus.
