Index to Part Five: Mountains and Aerial Perspective
Chapter list: aerial perspective on distant mountains, their color and darkness, and depicting alps and hills
The final index page in this run, listing rubrics 793-809 of the Trattato's fifth part, largely on the depiction of mountains. The chapters explain aerial perspective on distant peaks: why summits appear darker than bases, how their color fails to diminish evenly with distance, and how mountains take on blue when shaded by clouds. Further entries address the painter's deception over the size of trees, how to render the alps, hills, and mountainous landscapes, and the section closes with a precept. A running head and a foliation number appear on the sheet but are not part of the transcription.

Aerial perspective on distant mountains
The rubrics explain why distant mountains show darker summits than bases and why their color does not diminish evenly with distance. They also note the painter's deception in judging the size of trees and other features of the countryside.
Depicting mountains, alps, and hills
Further entries treat how mountains should not be painted as blue in winter as in summer, how those shaded by clouds take on the blue color, and the air that shows itself among the mountains. Later rubrics cover the division of mountains in painting and the rendering of the alps, hills, and mountainous landscapes, ending with a precept.
