BUILDING’S TWIN RECONSTRUCTION

The work shows a process that starts from the digitization of cultural heritage and through analysis arrives at the subsequent diachronic holographic representation. The object of the study was the creation of two holograms of historical buildings: the church of St. Maria in Sovana with an interesting subsoil and the ruin of church of St. Francesco, attributed to Sangallo il Giovane in Pitigliano. However, the theoretical setting of the research is placed at due distance from the twin term. It has implications and meaning that are not matched by producing a digital copy, even a very high resolution one. The use of different cognitive technologies and the assembly of the various inputs in a digital model can never be defined as a twin of the original. Bearing in mind what has just been specified, the work was organized according to different levels of acquisition of cognitive data. Obtained from the survey and from historical studies the shape of the original state, a historical narrative interweaving of digital models has been created.
