Leonardo is fascinated by the vortex movements not only of water but also of air and of blood in the heart ventricles and atria, which obey the same laws. In the Codex Leicester, he offers depictions of vortexes and their infinite variability that are unprecedented and would be unequalled for many years to come. With its spiral-shaped dynamics, the vortex expresses the irrepressible force of nature. Nothing can resist its demolition effects, which are continuously altering the surface and depths of the Earth.
