Works

His best known work is the Traité de Mécanique (1679), showing the parallelogram of forces. He also wrote Traité de la grandeur en general (1680) and Les éléments de géometrie (1685).

His writings are numerous and varied. Among them may be mentioned:
  • "Apparatus ad Biblia Sacra", etc. (Grenoble, 1687), translated into French by order of the Bishop of Châlons under the title "Introduction a la lecture de l'Ecriture Sainte" (Lyons, 1689).
  • "Harmonia, sive Concordia quatuor Evangelistarum", a harmony or concordance of the Four Gospels (Paris, 1689). In this work he contends that John the Baptist was twice cast into prison, first in Jerusalem by order of the Sanhedrin, and later by Herod in Galilee. He maintains also that the Saviour and His Apostles did not eat the paschal lamb at the Last Supper, and that the Crucifixion occurred on the day on which the Jews celebrated the Passover. He considers Mary Magdalen, Mary the sister of Lazarus, and the sinner mentioned in Luke, vii, 37 sqq. to be one and the same person. These and other opinions involved him in controversy with Bulteau, pastor of Rouen, Jean Piénud, Le Nain de Tillemont, and others (see "Traité historique de l'ancienne Pâque des Juifs", Paris, 1693).
  • "Apparatus Biblicus", which is a development of his introduction (Lyons, 1696; Jena, 1709; Amsterdam, 1710). It was translated into French by Abbé de Bellegarde (Paris, 1697) and by Abbé Boyer (Lyons, 1709). In this work he calls in question the historical character of the book of Tobias and book of Judith, and maintains that even after the Council of Trent

     a difference of authority should be recognized between the proto-canonical and deutero-canonical books of the Bible.
  • "Défense de l'ancien sentiment de l'Eglise latine touchant l'office de sainte Madeleine" (Rouen, Paris, 1697).
  • A volume of commentaries on his previous harmony of the Four Gospels (Paris, 1699).
  • A Latin treatise on the Ark of the Covenant (Paris, 1720), a posthumous work published by Père Desmollets, who prefixed to the volume a biography of the author.
