Chelidon (sister of Aëdon)
In Greek mythology, Chelidon (Ancient Greek: Χελιδών, romanized: Khelidṓn, lit. 'swallow') or Chelidonis is a minor figure, a noblewoman from either Miletus or Ephesus, cities on the western coast of Asia Minor. One of the daughters of Pandareus, Chelidon is presented as a virgin who is abused and violated by her brother-in-law Polytechnus and then forced to serve as a slave her older sister Aëdon before revealing her identity to her sister and transforming into a swallow in an Anatolian variant of the story of Philomela, though she might have had an independent origin in Attica, Philomela's homeland. The most significant difference between the two stories is that Chelidon, unlike Philomela, is not mutilated.
