Manuscripts on Perspective and Projective Geometry

This section is devoted to Leibniz’s work on geometrical perspective and its connection with the studies on the projection of curved geometrical objects. Leibniz already piqued an interest in perspective during his sojourn in Paris in the early years, but the development of an original theory on the topic began around 1680 and it had no significant developments after 1687. Leibniz’s aim was that of simplifying, with his new method, the relationship between the observer and the geometrical objects belonging to the objective and the apparent planes. Facing the challenge of establishing these relationships in the case of a curved apparent plane, he began to study in the same years the case of the projection of a sphere on a plane.
