I disegni di Rocco Capellino per le città di Oristano e Sassari

From the middle of the sixteenth century Rocco Capellino, a military engineer from Cremona, draws the project for the improvement of the city walls of Cagliari, Alghero, Sassari and Oristano. His work, however, was considered by the official history of a second level in respect to the measures which later will realize in Island the Paleari brothers. The graphical analysis of archival documents, however, shows a correct design approach set to use the existing towers like landmark, from which observe and measure the city and carry on with pointing the compass and draw according to modern models and rules indicated by the cross-fire of the artillery. This capacity, already found in the design for Alghero and Cagliari, is highlighted in this contribution through the graphical analysis of some unrealized projects for the cities of Oristano and Sassari.
