Louis-Sébastien Le Nain de Tillemont

Louis-Sébastien Le Nain de Tillemont (30 November 1637 – 10 January 1698) was a French ecclesiastical historian.

Life

He was born in Paris into a wealthy Jansenist family, and was educated at the Petites écoles of Port-Royal, where his historical interests were formed and encouraged. At the age of twenty, he began his two monumental works, the Mémoires pour servir à l'histoire ecclésiastique des six premiers siècles and the Histoire des empereurs et autres princes qui ont régné pendant les six premiers siècles de l'Église. 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 Mémoires in 1693. The publication of both works was not complete at the time of his death; the final volumes were completed and published posthumously by his secretary Michel Tronchay. Tronchay also published a biography of Tillemont in 1706 titled Idee de la vie et de l'esprit de M. L. de Tillemont.
