4 May, The Roman Martyrology

Quarto Nonas Maii Luna undecima Anno Domini 2020

On the morrow we keep the feast of the blessed John Fisher, Cardinal Bishop of Rochester, the blessed Thomas More, sometime Lord Chancellor of England, and many other martyrs, who won the palm of martyrdom strenuously fighting for the Catholic faith and the Primacy of Peter. Their veneration, allowed by Gregory XIII, was confirmed by a solemn decree of Leo XIII.
May 4th 2020, the 11th day of the Moon, were born into the better life:

At Ostia, that is the mouth of the Tiber, [in the year 387,] the holy Monica, the mother of blessed Augustine, as to whose illustrious life he hath left unto us his witness in the ninth book of his Confessions, and of whom we keep feast on the 14th
day of this present month of May.
At the mines of Phaeno, in Palestine, the blessed Silvanus, Bishop of Gaza, who was crowned with martyrdom, [in the year 311,] along with many of his clergy, by order of the Caesar Gallerius Maximian, in the persecution under Diocletian.
Also thirty-nine holy martyrs condemned to the mines at the same place, who, after they had been scorched with red-hot iron and had endured other torments, were beheaded at the same time.
