Notebook A page: treatise text with a ray diagram
Headed paragraphs of mirror-script prose closing with a small geometric ray figure; text untranscribed.
The leaf carries Leonardo's mirror-script in several short headed paragraphs, and at the lower right a small geometric diagram accompanies the text. The diagram shows straight lines diverging from a single point toward a marked vertical scale, the kind of construction used for perspective and for the study of light and vision. The bundle provides no transcription, so the wording is not rendered here, and further untranscribed text is present.

Chapters of untranscribed mirror-script prose
The main body of the page is continuous right-to-left text divided into short headed sections, in the manner of Leonardo's written treatise notes. No transcription is provided in this bundle, so the passages are not translated. The classification is inferred from the treatise structure and the accompanying diagram rather than read.
Ray diagram at the foot of the leaf
In the lower-right corner a small figure shows a set of straight lines fanning out from a single point on the left toward a vertical line or scale on the right, which bears short letter labels. It is the kind of point-to-scale ray construction used for perspective and for the study of light and vision. The letters are not transcribed here, and the figure is described from its visible geometry only.
