Geometric Figures: Polyhedra, Squares and Cylinders
Small solids crossed by diagonals on one leaf; cylinders and circles on the other
This opening carries only diagrams. Folio 104v bears a vertical column of small figures at the lower left — a triangular pyramid together with squares and rectangles crossed by their diagonals. Folio 107r shows several cylinders drawn in perspective with straight lines running across and between them, along with a few separate circles. No text accompanies the drawings.

Solids and diagonally divided figures
A stacked column of small figures is drawn at the lower left: a triangular pyramid, and squares and rectangles each crossed by their diagonals.
Cylinders and circles with crossing lines
Several cylinders are drawn in perspective with straight lines running across and between them, accompanied by a few separate circles.
