DUFRESNE, CHARLES, SEumEtni Du CM GE, hence generally styled merely DIICANGE, a French author, distinguished by his historical and linguistic writings, belonged to an ancient family of Picardy, and was born at Amiens, 18th Dec., 1610. After having received the rudiments of a scientific education at the Jesuits' college in his native town, he studied law at Orleans, and in 1631 became parliamentary advocate at Paris, where he continued to reside till his death, 23d Oct., 1688. There was scarcely any branch of science with which he was unacquainted, but his favorite studies were clas sical philology and history. Among his historical works may be mentioned the Hietoire de l'Empire de Constantinople sous lee Empereurs Francois (Paris, 1657). He also edited, along with other scholars, the Corpus Histories Byrantinm (Paris, 1680), and Joinville's Histoire de Saint Louis, 1?oi de France. His two principal works, however, are the Glossa rium ad Scriptores Media et Infinice Latinitatis (3 vols. fol., Paris, 1678; much enlarged by
the Benedictines of St. Maur, 6 vols, fol., Paris, 1733-36, to which four supplementary volumes were afterwards added by Carpentier, a Benedictine), and the Glossarium ad Scriptores Media et Infinus Grcecitatis (Paris, 1688). Both works display great learning, good judgment, and admirable industry, and are extremely valuable contributions to the study of the history and antiquities of the middle ages. A new edition of the Latin glossary, incorporating all the previous supplements, together with additions of his own, was published by G. A. Henschel (7 vols. 4to, Paris, 1842-53); and a supplementary volume (Latino-Germanieum) has since been added by Diefenbach (Fraucf. 1857). D. left a large quantity of valuable manuscripts, which have been collected in the univer sity of Paris.
