Eusèbe, a learned orientalist and ecclesiastical historian, was born at Paris in 1646, and was educated for the church at the Jesuits' College. He first became notable at court as a wonderful young scholar. His exhaustless linguistic knowledge, and the easy way in which he spoke many different languages, drew towards him the regard and confidence of several influential personages. Colbert, the great financial statesman, consulted him upon the project of establishing printing-presses in Paris for the oriental languages. The king himself employed him in various important missions to England, Spain, and other countries. The Cardinal de Noailles likewise took him to Rome in 1700, as his conclave in the conclave for the election of a Pope. Thus encouraged, Renaudot spent the chief part of his remaining years in illustrating the history and opinions of the ancient churches. His principal works on that subject were,—Défense de la Perpétuité de la Foi contre les Monuments Authentiques de la Religion des Grecs par Jean Ayman, in 8vo, Paris, 1708; Historia Patriarcharum Alexandrinorum Jacobitarum, in 4to, Paris, 1713; and Liturgiarum Orientalium Collectio, in 2 vols. 4to, 1716. Renaudot died in 1720. An English translation of the last of the above-mentioned publications appeared in 12mo, Dublin, 1822.
