a French ecclesiastic, was born at Grenoble, Aug. 28, 1635. He embraced at first the profession of arms, then resigned that in order to enter upon the ecclesiastical profession. Having become rector of Rueil, he had several conferences with the minister Claude, and, in order to confirm the faith of the new converts, he prepared a Refutation de l'Heresie de Calvin (published in Paris, 1787). He was in 1685 sent to the province of Vienna, to the general assembly of the clergy. He was appointed, in 1670, director of the devotees of Mt. Calvary, of Luxemburg, and two years later visitor of all this congregation. The abbe Blache had conceived a violent hatred for the Jesuits, and, on some of his writings on Christian doctrine becoming public, he was arrested in 1709 and sent to the Bastile, where he died, Jan. 29, 1714, having bequeathed all his goods to the Hotel-Dieu.
