DUPIN, LOUIS ELLIES (1657-1719), French ecclesi astical historian, was born at Paris on June 17, 1657, and educated at the college of Harcourt and the Sorbonne, receiving his B.D. (168o) and D.D. (1684) . The first volume of his Bibliotheque universelle de toes les auteurs ecclesiastiques appeared in 1686, but the liberty with which he treated the doctrines of the Fathers aroused the prejudice of ecclesiastics, including Bossuet, and, al though he consented to a retractation, the book was suppressed in 1696. He was subsequently exiled to Chatellerault as a Jansenist, but the sentence of banishment was repealed on a new retrac tation. His correspondence with William Wake, archbishop of Canterbury, with a view to a union of the English and Gallican Churches, threw further suspicion upon him. The same zeal for union induced him, during the residence of Peter the Great in France, and at that monarch's request, to draw up a plan for unit ing the Greek and Roman Churches. He died at Paris on June 6, 1719. Besides his great work, Dupin wrote a Bibliotheque universelle des historiens (2 vols., 1707) ; L'Histoire de l'eglise en abregti (1 712) ; and L'Histoire profane depuis le commence ment du monde jusqu'a present (4 vols., 1712) .
