The Myth: The story of Philomela, as told in Ovid's Metamorphoses and referenced by Eliot, is a brutal tale of sexual violence. Philomela is raped by her brother-in-law, King Tereus, who then cuts out her tongue to silence her. She is eventually transformed into a nightingale, and her song is a lament for her violation.
Eliot's Use: Eliot alludes to this myth in both "A Game of Chess" and "The Fire Sermon" to represent the sterile, meaningless, and violent nature of sex in the modern world. He places it in a modern context, where the cry of the nightingale is simply heard as "Jug Jug" by indifferent, "dirty ears," suggesting that the profound pain and suffering of the past have been debased and ignored in the present.
Contrasting with other options:The triumph of nature over humanity: While Philomela is transformed into a bird, this transformation is a result of immense suffering, not a triumph. It is a way for her to finally express her pain, not a celebration of nature's power.
The ability of art to speak where language fails: The story does contain this element, as Philomela weaves a tapestry to tell her story after her tongue is cut out. However, Eliot's emphasis is on the brutality of the act itself and the fact that modern ears can no longer understand the true tragedy in her song. The violence, not the art, is the central point.
The fleeting nature of love: The myth is about violation and lust, not the transient nature of love. The relationship depicted is founded on deceit and violence, not love.
