|St Agnes cup, c14th|
In the Office today we celebrate the feast of St Emerentiana, of whom the martyrology says:
"At Rome, the holy virgin and martyr, St. Emerentiana. Being yet a catechumen, she was stoned to death by the heathens while praying at the tomb of St. Agnes, her foster sister."
The martyrology also mentions St. Martyrius, a monk, mentioned by St Gregory the Great in his Dialogues, Book I:
"A certain man lived in that province, called Martirius, who was a very devout servant of almighty God, and gave this testimony of his virtuous life. For, upon a certain day, the other monks, his brethren, made a hearth-cake, forgetting to make upon it the sign of the cross: for in that country they use to make a cross upon their loaves, dividing them so into four parts: when the servant of God came, they told him that it was not marked: who, seeing it covered with ashes and coals, asked why they did not sign it, and speaking so, he made the sign of the cross with his hand against the coals: which thing whiles he was in doing, the cake gave a great crack, as though the pan had been broken with the fire: after it was baked and taken out, they found it marked with the sign of the cross, which yet not any corporal touching, but the faith of Martirius had imprinted."
