From the Roman Martyrology

“In Rome, on the Appian Way, of St Tarsicius the Acolyte, whom the heathen found bearing the Sacrament of the Body of Christ, and asked what is was that he bore; but he deemed it an unworthy thing to cast pearls before swine, and was therefore assailed by them for a long time with sticks and stones, and gave up the ghost; and when his body was moved, the sacrilegious assailants could find nothing of Christ’s Sacrament in his hands or among his clothing; but the Christians gathered up the body of the martyr, and buried it with honour in the cemetery of Callistus.” Martyrologium Romanum, 15th August.
