Leonardo de Vinci on Water

[water] percolates through all porous bodies. Against its fury no human defence avails, or if it should avail it is not for long. In its rapid course it often serves as a support to things heavier than itself. It can lift itself up by movement or bound as far as it sinks down. It submerges with itself in headlong course things lighter than itself. The mastery of its course is sometimes on the surface, sometimes in the centre, sometimes at the bottom. One portion rises over the transverse course of another, and but for this the surfaces of the running waters would be without undulations. Every small obstacle whether on its bank or in its bed will be the cause of the falling away of the bank or bed opposite it.
