PHILOMENA One of the two daughters of Pandion, Philomena and her sister Prokne exacted a terrible revenge on Tereus of Thrace, who obtained Proken as hiswife, but then wanted Philomena also, and pretending the former was dead, tore outher tongue to prevent her from revealing the truth. Prokne, however, embroidered thedetails of her mutilation on a piece of tapestry, and sent it to her sister. The two thenkilled the king's son, Itys, and placed his flesh before Tereus as a dish. Pursuing the two sisters, Tereus was turned into a lapwing, while Prokne was transformed into aswallow, Philomena becoming a nightingale.
