A 3D approach to investigate the burials: the virtual reconstruction of tb. 22 of necropolis of Piovego (PD)

The burials of the necropolis of Piovego (PD) have been subjected in the past years to processual research to reconstruct the post-depositional dynamics, thus providing a two-dimensional reconstruction of the original structure of the graves. The goal of this research is to define a new methodology on burial 22 of the necropolis, to replicate in other archaeological contexts. This new methodology aimed to create morphometrically accurate 3D models with a correct topological relationship between the grave finds and between them and the burial structure. 3D models of both the findings and structural elements of the burial were made from graphic documents with the aid of 3D modelling and 3D scanning techniques. The use of 3D models allowed the development of new hypotheses on the placement of the grave goods and their position within the space available in the burial. Furthermore, the models were useful to measure more accurately the perishable elements and to estimate their shape and position. The digital technologies allowed us to work in a threedimensional perspective, overcoming the limits of a traditional approach and verifying previous hypotheses on the topology of the burial, such as positioning of the finds and the existence of perishable materials that were not preserved.
