Circular sheet with a web of intersecting chords
A dense compass-and-straightedge lattice of radii and chords drawn around a central circle.
The e-Leo record marks this leaf as 'without writing' (Privo di scritti), and no text is transcribed. The circular sheet is covered by a finely ruled web of straight lines — radii and chords springing from points around the rim and forming a star-like lattice about a smaller central circle. A few faint marks appear inside the inner circle. The construction reads as a geometric or proportional exercise laid out with compass and straightedge.

Lattice of radii and chords about a central circle
Straight lines run from many points on the circumference across the disc, crossing one another to form a dense star-like net. At the centre they enclose a smaller plain circle crossed by a horizontal diameter. The regularity of the rays suggests a proportional or angular construction rather than a finished figure.
