louis-sÃ©bastien le nain de tillemont (30 november 1637 &ndash; 10 january 1698) was a french ecclesiastical historian. he was born in paris into a wealthy jansenist family, and was educated at the petites Ã©coles of port-royal, where his historical interests were formed and encouraged. at the age of twenty, he began his two monumental works, the mÃ©moires pour servir Ã  l'histoire ecclÃ©siastique des six premiers siÃ¨cles and the histoire des empereurs et autres princes qui ont rÃ©gnÃ© pendant les six premiers siÃ¨cles de l'Ãglise. the first is a history of the first six centuries of the christian church; the second is a history of the roman emperors during the same period. tillemont became a priest at the age of thirty-nine and settled at port-royal. when port-royal was dissolved in 1679, he moved to his family estate at tillemont, where he spent the rest of his life, pursuing his historical work with great devotion. his histoire began to issue from the press in 1690 and his mÃ©moires in 1693, though the publication of both works was not completed until after his death. tillemont is cited frequently by gibbon in his decline and fall of the roman empire. his works were among the first to provide critical surveys of the full range of source material. his prose style is considered dry, but he had a reputation for accuracy, detail and conscientiousness. his work was attacked on a large scale by honoratus a sancta maria in his rÃ©flexions sur les rÃ¨gles et l'usage de la critique, three volumes (1712-1720). ==references== *  ==external links== *
