Lamys studies resulted in a charming volume that illustrates the eighteenth-century attitude among the French authors of avoiding excessive abstraction in presenting the theory of perspective. Perhaps inspired by Leonardo da Vinci Lamy distinguished between perspective aërienne (aerial) and perspective lineale (linear), which was not very common in his day. He mainly concerned himself with linear perspective. ¶ In his practice of perspective Lamy concentrated upon the construction of the image of a grid of squares by means of a distance point method. He then used the perspective grid for various procedures, such as determining the perspective image of a plane configuration , constructing images on a vault , and creating an anamorphosis (Andersen, p. 472). ¶ Lamy was particularly important as an advocate for Cartesian philosophy within the French university. Lamy was educated first in the Oratorian college in Mans (1657-8), then entered the Oratorian house in Paris (1658-9), before attending the Oratorian collège at Saumur (1659-61). After collège, he taught belles lettres at Vendôme (1661-3) and Juilly (1663-8), where he was probably exposed to Cartesianism, perhaps by Nicolas-Joseph Poisson. Now a priest, Lamy returned to Saumur in 1669, first as a student of theology, then as a teacher of philosophy (1671-3). In 1673, he moved from Saumur to Angers. At Angers he got into considerable trouble for his Cartesianism and for following the teaching of Michel de Bay (Baïus). Expelled from Angers in 1675 for continuing to teach Cartesianism after the ban by Louis XIV, he was exiled to St. Martin-de-Miséré until 1676, when he was sent to Grenoble. In 1677 he was given a chair in theology at the seminary of Grenoble by the bishop Etienne Le Camus. Lamy was in Paris from 1686-1689. After an altercation with the archbishop of Paris over his Harmonia sive Concordia quatuor evangelistarum (Paris, 1689), he was sent to Rouen in 1689, where he stayed for the rest of his life (Garber, p. 1333).
