Life of Constantine

Now a certain woman, wife of one of the senators who held the authority of prefect, when she understood that those who ministered to the tyrant in such matters were standing before her house (she was a Christian), and knew that her husband through fear had bidden them take her and lead her away, begged a short space of time for arraying herself in her usual dress, and entered her chamber. There, being left alone, she sheathed a sword in her own breast, and immediately expired, leaving indeed her dead body to the procurers, but declaring to all mankind, both to present and future generations, by an act which spoke louder than any words, that the chastity for which Christians are famed is the only thing which is invincible and indestructible. Such was the conduct displayed by this woman.
