Nearly all the Latin Martyrologies commemorate these martyrs, without giving their names. Baronius [Cardinal Baronius (d. 1607), church historian who edited the Roman Martyrology] added to the Roman Martyrology, that they suffered under Ulpian the præfect; this was a conjecture of his, for Ulpian was bitterly hostile to the Christians, and it was under him that S. Martina (Jan. 1st) suffered. Alexander himself, only seventeen when he came to the throne, was of mild disposition, and the reins of government were in the hands of his mother Mamæa, who, with the approbation of the senate, chose sixteen of the wisest and most virtuous senators as a council of state, and at the head of this placed the learned Ulpian, a prudent governor, and severe disciplinarian, who could not brook that certain citizens should worship God in any way than that of the established religion, and looked on Christianity as a dangerous political element in the state, which demanded extirpation.
