Octagonal figures, interlaced constructions and numbers
Three concentric octagons, star-and-knot geometric patterns, and columns of arithmetic
The upper third of this sheet carries three concentric octagonal figures ruled in faint metalpoint, each divided by radial and ring lines. Below them run columns of numbers, of which the transcribed block records an arithmetic operation. The lower half is filled with intricate interlaced geometric constructions — rotated squares and star patterns built inside circles — with a compass-drawn circle crossed by intersecting curves and lines at the lower right. Only the arithmetic block was transcribed; the numeric jottings and geometric drawings are otherwise untranscribed.

Three concentric octagonal figures
Across the top of the sheet stand three octagons drawn in faint metalpoint, each nested with concentric octagonal rings and divided by lines radiating from the centre. They read as geometric constructions of the octagon. No transcribed text accompanies them.
Interlaced star constructions and a crossed circle
The lower half shows interlacing geometric figures — squares rotated within squares and star patterns set inside circles. At the lower right a compass-drawn circle is crossed by two intersecting curves and straight lines meeting in an X. These are geometric constructions rather than described figures.
Columns of arithmetic
A block of arithmetic runs across the middle of the sheet, including figures such as 334 1/5, 1324, 1035, 690 and a total of 7935. Further loose numeric jottings appear nearby but were not transcribed. The calculation is set among the geometric drawings.
Interlace and knot-like patterning
The lower-left constructions read as interlace: overlapping rotated squares and looping bands woven into knot-like patterns. Such geometric interlace is decorative as well as constructive. It carries no transcribed text.
