Phthia (mistress of Amyntor) in the context of "Clytie"

In Greek mythology, Amyntor (Ancient Greek: Ἀμύντωρ, translit. Amýntor, lit. 'defender') was the son of Ormenus, and a king of Eleon or Ormenium. Amyntor's son Phoenix, on his mother's urgings, had sex with his father's concubine, Clytia or Phthia. Amyntor, discovering this, called upon the Erinyes to curse him with childlessness. In a later version of the story, Phoenix was falsely accused by Amyntor's mistress and was blinded by his father, but Chiron restored his sight.

Amyntor was also the father of a son Crantor, and a daughter Astydamia. When Amyntor lost a war with Achilles' father Peleus, king of Phthia, Amyntor gave Crantor to Peleus as a pledge of peace. Strabo reports a genealogy for Amyntor which made him the grandson of Cercaphus, the son of Aeolus, and the brother of Euaemon, the father of Eurypylus.

In Greek mythology, the name Cleobule, Cleoboule, Kleobule or Kleoboule (Ancient Greek: Κλεοβούλη, Kleoboúlē) or Cleobula refers to:

• Cleobule, daughter of Aeolus or Aeopolus, one of the possible mothers of Myrtilus by Hermes.
• Cleobule, wife of Aleus of Tegea, mother of Cepheus and Amphidamas.
• Cleobula, mother by Ares of Cycnus who was killed by Heracles.
• Cleobule, mother of Amphimachus by Cteatus instead of Theronice.
• Cleobule, mother of Leonteus by Coronus.
• Cleobule, daughter of Eurytus and by Tenthredon, possibly the mother of Prothous, leader of the Magnesians during the Trojan War. Otherwise, Eurymache was called the mother of the Prothous.
• Cleobule, mother of Phoenix by Amyntor. Otherwise, Hippodameia or Alcimede was called the mother). Cleobule had two other possible children by Amyntor, Asydameia and Crantor. Cleobule was jealous of Amyntor's love for his concubine, Clytie or Phthia, so she convinced her son Phoenix to sleep with her, but when Amyntor found out, he cursed Phoenix with sterility.
• Cleobule, the Boeotian mother of Leitus by Lacritus; alternately, mother of Arcesilaus by Alector (Alectryon). Otherwise, Leitus' mother was Polybule by Alector or he was an earth-born, thus a son of Gaea. Meanwhile, Arcesilaus' parents were Areilycus and Theobule.
• Cleobule, mother of the tragedian Euripides by Apollo, as stated by Hyginus. Whether this is an otherwise unknown legend or simply the result of corruption of the text is uncertain.
