Chapter 4.
31 But they who were looking with their eyes, yet saw not, raged like robbers for prey, or wolves for a lamb. One who was more shameless went in. But when he took in the state of the matter with his eyes, he said, What is this? A maiden entered, now a man is to be seen here. This is not the old fable of a hind instead of a maiden, but in truth a virgin become a soldier. I had heard but believed not that Christ changed water into wine; now He has begun also to change the sexes. Let us depart hence while we still are what we were. Am I too changed who see things differently from what I believe them to be? I came to a house of ill-fame, and see a surety. And yet I go forth changed, for I shall go out chaste who came in unchaste.
32. When the affair was known, because a crown was due to such a conqueror, he was condemned for the virgin who was seized for the virgin, and so not only a virgin but a martyr came forth from the house of ill-fame. It is reported that the maiden ran to the place of punishment, and that they both contended for death. He said: “I am condemned to death, the sentence let you go free when it retained me.” And she replied: “I did not choose you as my surety on pain of death, but as a guarantee for my chastity. If chastity be attacked, my sex remains; if blood is sought, I desire none to give bail for me, I have the means to pay. The sentence was pronounced on me, which was pronounced for me. Undoubtedly, if I had offered you as security for my debt, and in my absence the judge had assigned your property to the creditor, you would share the sentence with me, and I should pay your obligations with my patrimony. Were I to refuse, who would not judge me worthy of a shameful death? How much more am I bound where there is a question of death? Let me die innocent, that I may not die guilty. In this matter there is no middle course; today I shall either be guilty of your blood or a martyr in my own. If I came back quickly, who dares to shut me out? If I delayed, who dares acquit me? I owe a greater debt to the laws who am guilty not only of my own flight, but also of the death of another. My limbs are equal to death, which were not equal to dishonour. A virgin can accept a wound who could not accept contumely. I avoided disgrace, not martyrdom. I gave up my robe to you; I did not alter my profession. And if you deprive me of death, you will not have rescued but circumvented me. Beware, pray, of resisting, beware of venturing to contend with me. Take not away the kindness you have conferred on me. In denying me the execution of this sentence, you are setting up again the former one. For the sentence is changed for a former one. If the latter binds me not, the former one does. We can each satisfy the sentence if you suffer me to be slain first. From you they can exact no other penalty, but her chastity is in danger with a virgin. And so you will be more glorious if you are seen to have made a martyr of an adulteress. than to have made again an adulteress of a martyr.”
33. What do you think was the end? The two contended, and both gained the victory, and the crown was not divided, but became two. So the holy martyrs, conferring benefits one on the other, gave the one the impulse and the other the result to their martyrdom.
