This volume investigates the mathematical foundations of celestial mechanics and the physical laws governing planetary motion as established in the broader Principia framework. The author, Pisanobussotti, provides a rigorous examination of the geometric proofs and physical principles that underpin the third volume of this foundational scientific work. The text utilizes classical mathematical methods to derive the behavior of bodies within a gravitational system, maintaining the logical structure characteristic of the original Newtonian tradition.

Scholars and historians of science frequently cite this volume as a critical resource for understanding the evolution of classical mechanics. Experts highlight the text for its technical precision and its adherence to the original structural arguments of the Principia.
