A Column Under Load, a Subdivided Square and a Colour Note
Geometry of intersecting lines in a square, beside a loaded column and a flesh-shadow pigment note
A slender column with a capital, drawn at the upper left, is captioned as a column with suspended weights, and small weights hang at its base as if in a loading trial. Below it a square is subdivided and lettered, with a note describing how the lines c d and e h intersect and enter into the segments f g and a b, repeated on the opposite faces. An upside-down line gives a painter's recipe - the shadow of flesh shall be burnt green earth - followed by a brief reminder to make cords.

Column with suspended weights
At the upper left rises a slender column with a capital, captioned as a column with suspended weights. Small weights hang from its base, suggesting a test of the column under load. No text elaborates on the trial.
Intersecting lines within a subdivided square
A square is subdivided and lettered c a b d and e f g h. Leonardo notes that c d intersects and enters into f g, that e h likewise intersects and enters between a b, and that the same is done on the other two opposite faces of the square.
Flesh-shadow rendered in burnt green earth
Written upside down is a painter's note that the shadow of flesh shall be burnt green earth, a pigment recipe for shading skin. A second short line adds an instruction to make cords.
