A geometrical study drawn in red chalk shows a semicircle or arch profile. It includes inscribed horizontal, vertical, and diagonal lines. Leonardo is likely exploring proportions or perspective projections. A darker, curved brushstroke in brown ink reinforces the right hand outer contour.

A geometric study from Leonardo da Vinci's notebooks, rendered in red chalk with brown ink annotations. The drawing depicts a semicircle containing a series of inscribed lines: a vertical axis, horizontal chords, and diagonals. This suggests a study of the internal proportions of an arch or a dome. The manuscript text in mirror script surrounding the figure provides technical commentary on the division of surfaces.
