On another occasion the saint was more successful. Laurentia, a maiden of youthful years, placed by her father within the sheltering walls of a cloister, to assume ultimately monastic vows, was quickly captured by an errant demon. As an irrefutable demonstration of the impure origin of her infirmity, an annalist asserts, this spirit promptly answered in elegant Latinity all questions propounded; but the strongest confirmation of this belief was the miraculous ability which enabled her to disclose the most secret thoughts of others, and divulge the mysterious affairs of her associates. St. Catharine at length liberated the suffering female from her diabolical tenant. More extraordinary claims are made for her. It is said that she stayed a plague at Varazze, and healed a throng at Pisa.[67] Raimondo da Capua, her faithful friend and constant companion, wrote her biography and gives us different instances of remarkable cures performed by her. For example, he tells us that Father Matthew of Cenni, the director of the Hospital of la Misericordia, was stricken when the plague was raging in Siena in 1373, and of his marvellous cure. Perhaps we had better allow him to tell of Catharine's power in his own words: "One day on entering, I saw some of the brothers carrying Father Matthew like a corpse from the chapel to his room; his face was livid, and his strength was so far gone that he could not answer me when I spoke to him. 'Last night,' the brothers said, 'about seven o'clock, while ministering to a dying person, he perceived himself stricken, and fell at once into extreme weakness.' I helped to put him on his bed; ... he spoke afterwards, and said that he felt as if his head was separated into four parts. I sent for Dr. Senso, his physician; Dr. Senso declared to me that my friend had the plague, and that every symptom announced the approach of death. 'I fear,' he said, 'that the House of Mercy (Misericordia) is about to be deprived of its good director.' I asked if medical art could not save him. 'We shall see,' replied Senso, 'but I have only a very faint hope; his blood is too much poisoned.' I withdrew, praying God to save the life of this good man. Catharine, however, had heard of the illness of Father Matthew, whom she loved sincerely, and she lost no time in repairing to him. The moment she entered the room, she cried, with a cheerful voice, 'Get up, Father Matthew, get up! This is not a time to be lying idly in bed.' Father Matthew roused himself, sat up on his bed, and finally stood on his feet. Catharine retired; and the moment she was leaving the house, I entered it, and ignorant of what had happened, and believing my friend to be still at the point of death, my grief urged me to say, 'Will you allow a person so dear to us, and so useful to others, to die?' She appeared annoyed at my words, and replied, 'In what terms do you address me?
