Étienne Pascal was rewarded for all his self-devotion by the genius of his son. His daughters also profited by his care, and became distinguished at once by their mental accomplishments and their personal beauty. A disaster that occurred, which at first disturbed the happiness of the family, tended in the end to establish it, and to bring into greater notice the talents and virtues of the individuals of which it was composed.
The finances of the government being at a low ebb, through mismanagement and long wars, the minister, cardinal de Richelieu, sought to improve them by diminishing the rate of interest towards the public creditor. Of course this act excited considerable discontent among holders of public stock; riots ensued, and some men, in consequence, were imprisoned in the Bastille. Among these was a friend of Étienne Pascal, who openly and warmly defended him, while he cast considerable blame on several government functionaries, and in particular the chancellor Séguier. This imprudence endangered his own liberty; he heard that he was threatened with arrest, and to avoid it left Paris, and for several months hid himself in Auvergne. He had many friends however among noble patrons of learning, and the duchess d'Aiguillon, in particular, interested herself in his favour. Richelieu, as is well known, was very fond of theatrical representations, and a tragi-comedy by Scuderi, was got up for his amusement. Jaqueline Pascal, then only fourteen years old, was selected to fill one of the parts: she at first refused, saying that the cardinal gave them too little pleasure for her to try to contribute to his; but the duchess saw hopes for the father's recall in the daughter's exertions, and persuaded Jaqueline to undertake the part. She acted charmingly, and at the end of the piece approached the cardinal, and recited some verses written for the occasion, asserting the innocence of her father, and entreating the cessation of his exile. The cardinal delighted, took her in his arms, and kissing her again and again, said, "Yes, my child, I grant your request; write to your father, that he may safely return." [Sidenote: 1639. Ætat. 16.] The duchess followed up the impression by an eulogium on Pascal, and by introducing Blaise; "He is but sixteen," she said, "but he is already a great mathematician." Jaqueline saw that the cardinal was favourably inclined; and with ready tact, added, that she had another request to prefer. "Ask what you will, my child," said the minister, "I can refuse you nothing." She begged that her father, on his return, might be permitted personally to thank the cardinal. This also was granted; and the family reaped the benefit. The cardinal received the exile graciously; and, two years after, named him intendant of Normandy at Rouen. Étienne removed with his family, in consequence, to that city. He filled the situation for seven years, enjoying the highest reputation for integrity and ability. About the same time, his daughter, Gilberte, formed an advantageous marriage with M. Périer, who had distinguished himself in a commission entrusted to him by the government in Normandy, and who afterwards bought the situation of counsellor to the court of aids of Clermont-Ferrand.
