Unveiling damnatio memoriae. The use of 3D digital technologies for the virtual reconstruction of archaeological finds and artefacts

In ancient Rome, damnatio memoriae was a practice of erasing the memory of condemned persons from historical records after their death. This practice was usually addressed by the Senate to Roman elites and emperors who were declared enemies of the State, in order to preserve the honour of Rome. This condemnation usually included practices such as, for example, the erasure of names sculpted on inscriptions and the destruction or reworking of statues and of any other image of the person. Emperor Nero, for example, was condemned to this practice immediately after his death and a wide iconographic repertoire on him was therefore destroyed or deeply damaged. This lack of information can actually be improved thanks to the possibilities of virtual restoration and reconstruction offered by 3D digital technologies. The aim of this paper is to show how the possibility to acquire 3D reality-based data from archaeological finds allows experts to build 3D digital models that can be analysed and managed in a virtual environment and can be relocated, assembled or restored in order to suggest or graphically support archaeologists’ interpretations and reconstructions. The paper shows the methodology developed for the virtual restoration of a statue of Nero starting from the 3D digitisation of the torso that was found 500 years ago near the Roman theatre of Bologna, Italy, the ancient Bononia
