Abstract
First edition of one of Borelli's major studies; in this work, his first book on mechanics, the author discusses percussion in detail, some general problems of motion, gravity, magnetism, the motion of fluids, the vibrations of bodies, pendular motion, and many other topics. Borelli considered this to be a necessary introduction to his De Motu Animalium.

"The first work on the laws of percussion, which undoubtedly influenced John Wallis, who in 1668 published his discovery of the laws governing the percussion of non-elastic bodies, and Christiaan Huygens, who deals on the percussion of elastic bodies in his treatise 'de motu corporum ex percussione,' published in 1669." --Sotheran 474.
