She is going to tell you what happened and she is going to tell it without the softening.
Phaedra is the daughter of Minos and Pasiphae - born into the house where the impossible desire had already been, raised in the shadow of her mother's punishment and her brother in the labyrinth. She was given to Theseus, the hero who had killed her brother and abandoned her sister, and she made what she made of the marriage. She was competent. She managed the household of the hero who was never present. She did not love him.
Then Hippolytus came home.
PHAEDRA: WHAT SHE KNEW is the account of the disaster told from inside it - from inside the desire that was Aphrodite's instrument and the choices that were Phaedra's own. She tried to refuse the desire for months. She failed. Her nurse told him. He was disgusted. He said he would tell his father. And Phaedra, who knew exactly what she was doing, told Theseus first.
She accused Hippolytus of the thing she had done herself. She reversed the thing. Theseus cursed his son. Hippolytus died - keeping the oath he had sworn to her nurse, refusing to tell the truth even when the truth would have saved him. He died keeping her secret.
She gives the full account: the soil was Aphrodite's. The choices were hers. Both things are true. Neither excuses the other.
He kept the oath. He was worth more. Let the record hold this.
