Apronianus then attacked them to make them worship the gods of the Gentiles, and promised them the restoration of their property, the favour of the Emperor, and a great marriage for each of them, if they would give way, and, on the other hand, imprisonment, stripes, and death. But neither promises nor threats availed, for they remained firm in the faith, being resolved rather to die than to pollute themselves by doing according to the deeds of the heathen; and, as for the iniquity of the Governor, they loathed it continually. At length the strength of Demetria gave way, and she fell down suddenly, and died in the Lord, before the eyes of her sister Bibiana. Then Bibiana was put into the hands of an artful woman named Rufina, to seduce her if possible; but she had known the law of Christ from her childhood, and kept the lily of her purity undefiled, triumphing over the efforts of that vile person, and disappointing the lust of the Governor.
Then, when Rufina saw that her false words availed not, she took to blows, and scourged Bibiana daily, but the saint was not staggered in her holy resolution. At last the Governor, mad with baffled lust, when he found his labour was thrown away, ordered his lictors to strip her naked, hang her up by the hands to a pillar, and flog her to death with whips weighted with lead. When all was over, her sacred body was thrown out for the dogs to eat. It lay two days in the Forum Tauri, but the animals would not touch it; and, at last, a Priest, named John, took it, and buried it by night beside the graves of her mother and sister, near the Licinian Palace. This is the place where there is still a church, dedicated in the name of St. Bibiana. When this church was being restored by Urban VIII, the bodies of these three holy women, Bibiana, Demetria, and Dafrosa, were found, and were re-buried under the High Altar.
