[LEMONIER, Pierre - Collège de HARCOURT]. 'Geometria juxta doctrinam D.D. &c by Pierre Le Monier, Professor of Philosophy at Harcourt, in the year of our Lord 1732. Manuscript on in-4° paper, comprising 77 numbered leaves, plus 4 unnumbered leaves (index) + 'Physica,' comprising 174 numbered leaves, plus 4 unnumbered leaves (index). Contemporary full calf binding (scuffed, corners worn), spine with gilt raised bands (cap caps missing), red morocco labels bearing the titles 'Physica' and 'Tom III'. The lecture notes are written by the student in fairly legible Latin in a notebook featuring a frontispiece engraved with an allegory of Geometry, an engraved title page, 7 folded plates engraved by Hecquet and 3 folded plates by Vallet for the geometry section, and for the 'Physics' section, an allegorical frontispiece of 'Physica', an engraved title page with a blank center for the student to add a title, and 4 folded plates numbered 7 through 10 by Hecquet. In addition, the manuscript is adorned with full-page portraits engraved by Vallet of Thales, Heraclitus, Democritus, Gassendi, Zeno, and Descartes. Some of Vallet’s engravings are dated 1726; the title page for *Geometria* is dated 1713. The lectures were attended in 1731 and 1732. A fine example of lectures copied by students at the Collège d’Harcourt into notebooks prepared in advance by engravers/printers, containing the drawings necessary for understanding the professor’s dictation. Pierre Le Monier (1675–1757), an astronomer and geometer, served as an assistant and later as an associate geometer at the Academy of Sciences. He was the father of the astronomer Pierre Charles Le Monnier and of Louis Guillaume Le Monnier, a physician and botanist, both of whom were also members of the Academy of Sciences.
