Lonis Francois Desire Edonard Pie, a French bishop, born at Pontgouin, Eure-et-Loire, Sept. 26,1815. Soon after his ordination he was appointed vicar general of Chartres, and on May 23,1849, he became bishop of Poitiers. Though warmly attached to the legitimist party, he gave at first a qualified adhesion to Napoleon III.; but in refuting, in 1861, La Gueron-ni&re's pamphlet La France, Rome et Vltalie, he compared Napoleon III. to Pontius Pilate, responsible for the death of Christ. He was summoned to answer for this offence before the council of state, but refused to appear. In 1869 he took a prominent part in advocating a speedy declaration of pontifical infallibility; and in the Vatican council he was the leader of the French infallibilists, and reported back to the council, May 14, 1870, the schema on the primacy of St. Peter and the official infallibility of his successors. His principal publications are: Instruction synodale sur les erreurs de la philosophic moderne (Poitiers, 1855); Discours et instructions pastorales (3 vols. 8vo, 1858-60); Instruction synodale sur les principales erreurs du temps present (1864); and two series of discourses and pastoral instructions in vol. xvi. of Migne's Collection des orateurs sacres.
