Ducal garden pavilions and a square-bastion fortress
Foundations of Milan's ducal pavilions, a tiled roof, and a fortress with twin round towers
The sheet gathers architectural studies for the Milanese court alongside military engineering. A perspective of a tiled roof and two centrally-planned garden pavilions are noted as the foundation of the pavilion at the centre of the Duke of Milan's labyrinth and as the domed pavilion of the Duchess's garden. Below, a large perspective view of a square bastion set with two round towers and ravelins is worked out, together with a small fortress plan giving the foundation of the lower ravelin. The captions specify the pavilion's water basin (20 braccia) and the bastion's dimensions.

Foundation of the pavilion in the Duke of Milan's labyrinth
A circular plan shows a ring of piers arranged like an octagon around a central point, with a surrounding water basin of 20 braccia. It is captioned as the foundation of the pavilion standing at the centre of the Duke of Milan's labyrinth.
Domed pavilion of the Duchess of Milan's garden
A section of a circular building crowned by a ribbed dome and lantern is drawn in the middle of the page. The caption identifies it as the pavilion of the Duchess of Milan's garden.
Square bastion with two towers and ravelins
The large perspective at the foot of the page develops a square bastion given only two round towers so that flanking fire from one does not strike the other. Each tower has a bridge leading into a ravelin. The bastion is to be 100 braccia across and each tower 30, with the ravelins left open at the rear so a captured one gives the enemy no cover.
Foundation of the lower ravelin
A small fortification plan is captioned as the foundation of the lower ravelin, one of the outworks belonging to the bastion scheme.
Octagon and square inscribed in a circle
A faint dotted construction at the upper left lays out a square and an octagon, the geometric basis for the centrally-planned pavilions on the sheet.
