All the fragments undergoing restoration and conservation treatments were photographed twice: at the time of packing in the temporary workshop at Alghero (Sardinia), and after cleaning in the CCA laboratory at Belmonte in Sabina. They kept their original classification based on excavation year, number of stratigraphic section and box number, which was established by the archaeologists at the time of the excavation.
Photographic documentation was preliminary to the study of the matching fragments based on typological and decorative analogies. Each photograph was archived in a database created with FileMaker. The database entries include the photographs of the finds, their description and their stratigraphic origins.
All data were cross-referenced, obtaining a correlation of images and text that helped searching the matching fragments. Analyzing the results, more than 1000 fragments were assembled, obtaining a partial reconstruction of the decorative layout of the rooms. Decorative, typological and production details, revealed by cleaning, and alterations/damages of the surfaces disclosed matching pieces. They could be assembled to reconstruct the original revetment slabs, opus sectile floor tiles, painted wall decoration.
Eventually the database allowed a reconstruction of the decorative typologies, the identification of the fragments of each stratigraphic unit and their features. Each decorative type was, therefore, graphically reconstructed in 1:25 scale. These drawings are currently used to create a map of the state of conservation.
