Map of the Lower Arno Valley: Caprona, Vico, Montecchio
Topographic survey with a fortified plan and columns of calculation
A topographic drawing in red chalk maps a stretch of the lower Arno valley, its watercourses and roads threading between hills, with locality names written across it. The transcribed caption gives the places Verrucola, Caprona, Vico and Montecchio, sites in the Pisan territory. Toward the center-right an angular plan of a fortified work is laid out, and columns of figures run down the right margin. Much of the page's handwriting is untranscribed beyond the place-name caption.

Place-names of the surveyed territory
Locality names are inscribed over the mapped terrain to fix the survey. The caption above the figure lists Dolorosa Verucola, Caprona, Vico and Montecchio.
Plan of a fortified work
An angular, geometric outline is drawn among the roads and watercourses, reading as the plan of a fortification set into the terrain. It ties the map to the fortress-ditch excavation studied on the facing leaves.
Columns of figures in the margin
Stacked numbers and short sums run down the right edge of the sheet, of the kind used in the adjoining excavation-cost reckonings.
