Overview of Scientia Perspectiva (1684 – 1687)
Dated between 1684 and 1687, Scientia perspectiva may very well be Leibniz’s last attempt to develop a comprehensive theory on geometrical perspective. Ideally, the manuscript could be divided in five parts: a first introductory part on the concepts involved in perspective and the main aim of this science, a second part concerning a general example of Leibniz’s method and its fundamental theorem, a third part on how geometrical objects appear in the apparent plane with respect to the objective plane, a fourth part with a more sophisticated example of how similar triangles are involved in determining the various points in the apparent plane and a fifth, last part where Leibniz develops a general rule for perspective, concerning parallel lines, converging lines and relative points.
