Canal profiles, falling water, and the Vigevano pavilion
Red-chalk water studies with a corner detail of the timber pavilion at Vigevano
A red-chalk (sanguigna) leaf, drawn with the page turned upside down, mixing hydraulic sketches with an architectural detail. One note observes that water falling into still, flat water strikes it obliquely so that the descent runs faster, keyed to a lettered canal profile (c, n, b, a, s). Separate sketches show the narrowing (strozzatura) of a canal and, at the foot, a corner of the timber pavilion of Vigevano. Faint further sketching is present around these motifs.

Water falling into still water runs faster
Water that drops into flat, standing water strikes it at a slant, so the descent becomes more rapid. The effect is traced along the lettered profile, running from b to a and declining from c to b.
Corner of the timber pavilion of Vigevano
A detail labelled as the corner of the plank (timber) pavilion, tied to the pavilion of Vigevano named in the caption. The lower drawing shows a framed structure with a circular element inside it.
Narrowing of a canal
A small study captioned as the constriction (strozzatura) of a canal, showing how the channel is pinched between its banks. No accompanying descriptive text is transcribed for this figure.
