Procne. (n.d.). Retrieved March 24th, 2019, from https://www.yourdictionary.com/procne
An Athenian princess who avenged the betrayal and cruelty of her husband, Tereus, by killing their son. She and her sister Philomela were changed into a swallow and a nightingale as Tereus pursued them.
According to Roscher (in his Lexikon der Mythologie), who identifies the ciris with the heron, the story of Nisus and Scylla (like these of Acdon, Procne, Philomela and Tereus) was invented to give an aetiological explanation of the characteristics of certain birds.
