PROCNE
From Wikipedia, the free encyclopediaIn Greek mythology, Procne or Prokne was a daughter of Pandion and Zeuxippe. She married Tereus and had one son: Itys. Tereus loved his wife's sister, Philomela. He raped her, cut her tongue out and held her captive so she could never tell anyone. Philomela wove a tapestry that told her story and gave it to Procne. In revenge, Procne killed her son by Tereus, Itys, and fed him to Tereus unknowingly.
Tereus tried to kill the sisters but all three were changed by
the Olympic Gods into birds: Tereus was a hoopoe (or, in Ovid,
a Lapwing); Procne was a swallow; Philomela was a nightingale
whose song is a song of mourning. The name "Philomel" is often
sometimes used in poetic literature to refer to a
nightingale.
