Map of Stabile di Guastalla

The drawing shows all the land of the vast estate of Guastalla di Sona in 1774, south-east of Lake Garda, then owned by the Marquis Giorgio Spolverini-dal Verme.
In the middle of the upper margin, inside a cartouche, is the title of the drawing: Stable / of / Guastalla, symmetrically, in the lower margin, you read the coat of arms Spolverini-dal Verme.
Particular is the representation of the compass painted in the middle of the map, decorated with a bouquet of flowers and also legible as wind rose, in fact the ring of the needle watercolored in blue actually indicates the initial letter “O” of ostro, that is the hot and damp wind from the South.
Four cartouches describe the intended use of the fields, for a total of 2 478 Verona fields.
Centrally located in the map is depicted the Palace of Guastalla, the axonometric representation is surprising for the fidelity of details.
