One day, it is recorded, several gentlemen had been dining with Lorenzo; and one of them after dinner drew from his pocket a book which contained a treatise on magic. Lorenzo took it up, and was examining it with some curiosity, when his wife stole noiselessly behind him, took it out of his hands, and threw it into the fire. Nettled by this proceeding, her husband reproached her in rather bitter terms for her incivility to their guest; but she, who was habitually submissive to his least word, only replied that she could not regret the destruction of what might have proved to many an occasion of sin. She inexorably consigned to the flames in the same manner every bad book that came in her way.
Her tender charity was evinced when any of the inmates of the palace were ill. She was then the affectionate nurse of the sufferers, and spent whole nights by their bedside. Nothing ever discouraged or wearied her; the lowest servant in the house was attended to, as if she had been her own mother or sister. More anxious still for their soul's health than their body's, she was known to go out herself alone at night in search of a priest when a sudden case of danger had occurred beneath her roof. Her charity was in one instance miraculously rewarded by a direct interposition of Providence, in a matter apparently trifling, but on which, humanly speaking, her dear sister Vannozza's existence seemed to turn. She was dangerously ill, and had been for days unable to swallow any food; the very sight of it caused her intolerable nausea; and from sheer exhaustion her life was reduced to so low an ebb, that the worst was apprehended. On Francesca's inquiring if she could think of any thing which she could imagine it possible to eat, she named a certain fish, which was not in season at that time. The markets were scoured by the servants, but naturally in vain, and they returned empty-handed to the dejected Francesca, who, kneeling by the bedside of her friend, betook herself, with arduous faith and childlike simplicity, to prayer. When she raised her head, the much-wished-for article of food was lying before her; and the first morsel of it that Vannozza eat restored her to health.
She had been about a year at the head of her father-in-law's house, when Rome fell under the double scourge of famine and pestilence. The Ponziani were immensely rich, and their palace furnished with every kind of provisions. Francesca forbade her servants to send away a single poor person without relieving their wants; and not content with this, she sought them out herself, invited them to come to her, and made them continual presents of corn, wine, oil, and clothing. She exhorted them to bear their sufferings with patience, to return to God and to their religious duties, and to strive by fervent prayer to appease the Divine wrath, provoked by the crimes of mankind. Vannozza and herself were indefatigable in their visits to the hospitals and the out-of-the-way corners of the city.
