Sheet-like Water Around Obstacles in a Swift Current
Water spectacles: incident veils of water versus real reflected water
Leonardo describes how to make beautiful spectacles of veil-like water by placing many objects in a low, even, swift current. Water striking and girding an object divides into two qualities: a sheet-like incident water and a real reflected water. The objects are a b, of which b is girded by the water r s t and turns into the sheet e f m o, while the real water is h. A drawing at the right shows the streaming water flowing around the obstacles.

Making sheet-like water around submerged objects
To make beautiful spectacles of veil-like water, many objects are set in a low, even, swift current. The objects are a b; b is girded by the water r s t, which then converts into the sheet e f m o, while the real water is h.
Two qualities of water striking an obstacle
The swift water that strikes and girds an object is of two qualities: the first sheet-like and incident, the other real and reflected. The distinction separates the thin veil thrown forward from the body of water turned back.
