St. Ambrose, Concerning Virginity, Bk. I, Ch. II: “It is the birthday of St. Agnes, let men admire, let children take courage, let the married be astounded, let the unmarried take an example. But what can I say worthy of her whose very name was not devoid of bright praise? In devotion beyond her age, in virtue above nature, she seems to me to have borne not so much a human name, as a token of martyrdom, whereby she showed what she was to be.”
