D’Eon in her own words

  • Let the world be taken aback by my transition, it even astonishes me.

  • Do you know why I suffer on earth like a very impatient patient? It's because the law has declared and pronounced me to be a woman despite myself, so that I no longer follow my own will, but that of God, of the law and of the King.

  • O woman of little faith! Tell me if you please, what sex is my soul, you, who at my birth could not say what sex my body was?
