Sheet of geometric studies: lunes, vaults and radial plans
Numerous small pen studies of curved figures, centralized plans and inscribed figures, without accompanying text
A densely worked sheet of small pen sketches with no transcription supplied. It gathers many studies of lunes and curved-sided (falcata) figures, hatched vault- and sail-like curved surfaces, circles with inscribed triangles and diameters, and small square grids. Alongside these run centralized figures drawn as radiating plans: an octagon spoked to a central circle and concentric squares set about a central circle, together with pinwheel rosettes and a goblet-like form.

Studies of lunes and curved-sided figures
The right and centre of the sheet carry many small studies of lunules and falcata figures, several shaded with hatching to read as curved surfaces or vaults. A circle inscribing a triangle with its diameters appears among them.
Centralized radial plans
At the upper and lower left are centralized figures resembling ground plans: an octagon divided by spokes to a central circle, and concentric squares set about a central circle. These radial, symmetrical layouts recall centralized plan schemes.
