Roman Martyrology-August 13th- on this date in various years-
At Rome, the blessed Hippolytus, martyr, who gloriously confessed the faith, under Emperor Valerian. After enduring other torments, he was tied by the feet to the necks of wild horses, and being cruelly dragged through briars and brambles, and having all his body lacerated, he yielded up his spirit. On the same day suffered also blessed Concordia, his nurse, who being scourged in his presence with leaded whips, went to our Lord, and nineteen others of his household, who were beheaded beyond the Tiburtine Gate, and buried with him in the Agro Verano.
At Imola, the birthday of St. Cassian, martyr. As he refused to worship idols, the persecutor called the boys whom the saint had taught and who hated him, giving them leave to kill him. The torment suffered by the martyr was the more grievous, as the hands which inflicted it, by reason of weakness, rendered death long drawn-out.
At Todi in Umbria, St. Cassian, bishop and martyr, under Emperor Diocletian.
At Burgos in Spain, Saints Centolla and Helena, martyrs.
At Constantinople, St. Maximus, a monk distinguished for learning and for zeal for Catholic truth. Valiantly disputing the Monothelites, he had his hands and tongue torn from him by the heretical emperor Constans, and was banished to Chersonesus, where he breathed his last. At this time, two of his disciples, both named Anastasius, and many others endured divers torments and the hardships of exile.
At Fritzlar in Germany, St. Wigbert, priest and confessor.
At Rome, the birthday of St. John Berchmans, a scholastic of the Society of Jesus, illustrious for his innocence and for his fidelity to the rules of the religious life. He was canonized by Pope Leo XIII.
At Poitiers in France, St. Radegund, queen, whose life was renowned for miracles and virtues.
And elsewhere in divers places, many other holy martyrs, confessors, and holy virgins.
R. Thanks be to God.
