Gaspard Monge's Descriptive Geometry

A page from the 1811 edition of the Descriptive Geometry of Gaspard Monge (1746-1818). This book deals with methods for representing three-dimensional objects in two dimensions. It was written to accompany Monge's courses at the √ącole Polytechnique in Paris.

This page (plate 14) illustrates projections obtained by cutting a cone with an oblique plane.
