Light Rays from a Sphere Converging to a Point
A light-and-shadow diagram: a body at left sends rays to a single point beneath a broad arc
A geometric diagram sits between two blocks of Leonardo's mirror-written Italian, none of which is transcribed in this bundle. A spherical body rests at the left end of a horizontal base line, and straight rays fan out from it and from the arc above to converge toward a single small point at the right. The construction belongs to Manuscript A's sustained study of how light relates a luminous or opaque body to a point of sight or of shadow. Further untranscribed text is present on the sheet.

Rays gathered from a sphere to one point
The drawing places a circle, read as a spherical body, at the left of a ruled horizontal line. Fine straight lines run from the body and from the overarching curve toward a single convergence point set well to the right. The figure treats light and shadow as a matter of geometry, tracing how rays link an extended body to a point.
Surrounding discourse (untranscribed)
Dense passages of mirror-written Italian fill the upper and lower thirds of the sheet, framing the diagram. This text is not supplied in the bundle and is not transcribed here. It evidently forms the explanatory argument attached to the light-and-shadow construction.
