“Veue de la ville de Boze”. A Seventeenth-Century View to Analyse the Transformations of the Landscape of the City of Bosa (Sardinia, Italy)

The contribution presents an analysis of the “Veue de la ville de Boze”, a 17th century view of the city of Bosa (Sardinia, Italy). The document is particularly interesting as it offers a detailed description of the landscape shapes; this aspect is functional to a reconstruction of the historical assets and of the transformations occurred in the last three centuries, also thanks to the current digital resources that support the diachronic analysis and the sharing of the results. The image, “built” according to proven methods of survey and representation of the territory, frames from the top of the plateau of Sa Sea, the city protected by a wall that connect numerous towers and by the thirteenthcentury castle of Serravalle. The highlands that characterize the landscape of the hinterland, the river Temo that laps the urban center and reaches the sea along a fertile valley, the island called “Isola rossa” with the sixteenth-century tower and the marshy area of “S’Istagnone”, are just some of the elements clearly identified, each of which, although mediated in the pictorial interpretation, useful piece for an in-depth examination of the architectural-landscape system. However, the study of the document wants to go “beyond the line”, analyzing the elements recorded in the map and the operating procedures employed but above all searching and highlighting the graphic choices and the “communicative” intent of the author.
