DUPERIION, JACQUES DAVY (1556-1618), a celebrated French cardinal, was born at St LO, in Normandy, November 15,1556. His father was educated for a physician, but on embracing the doctrines of the Reformation became a Protestant minister, and to escape persecution settled at Bern, in Switzerland. Here Jacques Davy received his education, being taught Latin and mathematics by his father, and learning without the aid of any one Greek and Hebrew and the philosophy which was then in vogue. At twenty yearn of a_e he c.ame to Paris, and was presented to the king by the count of Matignon ; and, after he had abjured Prote.stantism, being again presented by Philip Desportes, abbot of Tiron, as a young man without equal for knowledge and talent, he was appointed reader to the king. He was commanded to preach before the king at the convent of Vincennes, when the success of his sermon on the love of God, and of a funeral oration on the poet Bonsard, induced him to take orders. On the death of Mary Queen of Scots Ile was chosen to pronounce her eulogy, which, though it contained an attack on Elizabeth of England that the king thought it prudent to disavow, tended to advance both the ecclesiastic's fame and fortune. When the Cardinal de Bourbon, at the end of Henry III.'s reign, plotted to secure to himself the throne to the prejudice of Henry IV., Duperron is accused of having joined in the plot and re-vealed to Henry IV. its secrets. However that may be, when the plot felled, and Henry IV. mounted the throne, Daperron enjoyed the favour of that monarch, and in 1591 was created by him bishop of Evreux. He con-verted Henry to the Catholic religion ; and, after the taking of I'aris, accompanied the Cardinal d'Ossat to Rome to obtain the removal of the interdict which had ?been passed upon France. On his return to his diocese, his zeal and eloquence were largely instrumental in with-standing the progress of Calvinism, and among others he converted Henry Sponde, who became bishop of Pamiers, and the Swiss general Sancy, His success attracted the attention of the church, and he was chosen to represent it at the conference at Fontainebleau in 1600. In 1604 he was sent to Rome as "charge d'affaires de France ;" and, having hardly arrived when Clement VIII. died, he largely contributed by his eloquence to the election of Leo XI. to the papal throne, and, on the death of Leo twenty-four days after, to the election of Paul V. While still at Rome he was named archbishop of Sens, and the same year was made a cardinal. Ile died at Paris, Sept. 6, 1618. Duperron was a zealous defender of the infallibility and power of the Pope, and of his superiority over a general council. He was pos-sessed of immense energy, aud of a ready and convincing eloquence, which he could make available for whatever (minions he thought it prudent to ,adopt ; and, if he did not form his opinions solely with a view to his advancement, they certainly adapted themselves in each case with remarkable appropriateness to the different emergencies and turning points of his life. His works were collected after his death, and published in three volumes in 1622-23
