---- Seconde édition française de ces deux ouvrages traduits par le père Antoine Rivière avec un essai sur la théorie des couleurs de NEWTON ---- "Brook TAYLOR, mathématicien anglais, étudie expérimentalement les questions scientifiques de son temps et donne une nouvelle théorie de la perspective" ---- "TAYLOR developed his theory of perspective in a formal and rigorous fashion in a sequence of theorems and proofs. The most aoutstanding and original of his ideas in this fiels were his definition and use of vanishing points and vanishing lines for all lines and planes, and his developement of a theory and practive for the inverse problem of perspective that later served as a basis for work by Lambert and for the development of photogrammetry. TAYLOR also made free use of the idea of associating infinitely distant points of intersection with parallel lines, and he sought to devise mehtods for doing geometric constructions directly in perspective".
