St. Agatha of Sicily (Wikipedia)
"O God, Who among the other marvels of Thy power, hast granted even to the weaker sex the victory of martyrdom: mercifully grant that we who celebrate the heavenly birthday of blessed Agatha, Thy Virgin and Martyr, may by her example draw nearer to Thee. Through our Lord." - Roman Catholic Daily Missal, 1962
St. Agatha, born in Sicily of noble parents, suffered a glorious martyrdom at Catania In the persecution of the emperor Decius. For when Quintianus, the praetor of Sicily, had vainly tried every means to tempt her from her virginity, he had her arrested as adhering to the Christian superstition. First she was beaten,then tortured on the rack with white hot iron plates laid on her; then one of her. breasts was cut off. Next she was thrown into prison, where St. Peter the Apostle appeared to her by night and healed her. Again called before the praetor she persevered in confessing Christ, and he had her rolled over broken pottery and burning coals. But then a great earthquake violently shook the city, and Ouintianus, afraid of a riot among the people, gave orders that Agatha, now half dead, secretly be taken back to prison. There after a short time she went to heaven on February 5. - 1960 Roman Breviary
