This Day, the Thirteenth Day of May

At Constantinople, under the emperor Diocletian and the proconsul Laudicius, the blessed Lucius, a priest and martyr, who first at Amphipolis endured many tribulations and torments for the confession of Christ, and then being led to Byzantium, suffered capital punishment.

At Heraclea, the martyr Saint Glyceria, a native of Rome, who suffered under the emperor Antoninus and the governor Sabinus.

At Alexandria, the commemoration of many holy martyrs, who were killed by the Arians for the Catholic faith in the church of Saint Theonas.

At Maestricht, Saint Servatius, bishop of Tongres, whose grave, as a public sign of his merit, was free from snow during winter (though everything around was covered with it), until the inhabitants built a church over it.

In Palestine, Saint John the Silent.

At Valladolid, Saint Peter Regalati, confessor, of the Order of Friars Minor, restorer of regular discipline in the monasteries of Spain. He was numbered among the Saints by the Sovereign Pontiff, Benedict XIV.

R: Thanks be to God
