Philomela's Retold Story: Silence, Music, and the Post- Colonial Text:

TLDR: Procne and her younger sister, Philomela as mentioned in this paper proposed a tapestry which reconstructed the story of her rape, and then plotted her revenge, treating Tereus to a succulent meal consisting of his own son.

Abstract: to secure a vital alliance with the Thracian King, Tereus, by offering his eldest daughter, Procne, in marriage. Lonely in Thrace, Procne pleaded with Tereus for her younger sister, Philomela, to come out and join her. Tereus agreed and went to fetch Philomela. He brought her back to Thrace, but not before he had forced his affections on her, raped her and, to prevent her from complaining, cut out her tongue. Philomela still found a way of making herself understood, however, by embroidering a tapestry which reconstructed the story of her rape. Realizing what had happened, Procne plotted her revenge, treating Tereus to a succulent meal consisting of his own son. Bursting with rage (and indigestion?) Tereus went after the two sisters with an axe.
