On the double increase of the forces of the muscles flexing the forearm and the lower leg

  • Giovanni Alfonso Borelli


As clearly enunciated by divine Plato, Geometry and Arithmetics are two wings by which we ascend to heaven since they enable us to understand the arcanes of Astronomy. We can also claim that Geometry and Mechanics are the ladders by which we climb to the wonderful knowledge of the movements of animals. Who could deny this fact which has been demonstrated in the two previous chapters? However, since we were not more used to mechanics, we missed the truth by far, not because we tolerated error and what has been said hitherto must be rejected but because, although some of it is true, we did not follow more exact science. For better understanding some mechanical lemmas must be presented which, as far as I know, have not been considered hitherto.
