The volume presents the important archaeological discovery of the mosaic floors of Savignano sul Panaro, which took place "almost" by chance following public road works. The discovery had already taken place at the end of the nineteenth century with the excavations of Crespellani, but the mosaic floors were reinterred, leaving however a precious documentation represented by a series of watercolors reproducing the mosaics. The current excavation began in 2010 and saw the Roman mosaics, dated to the XNUMXth century, come back to light. The protection needs were combined with an effective enhancement activity through the detachment of the mosaics, their restoration and museum creation; all this was possible thanks to the availability of the Province of Modena, one of the very first provinces that managed to acquire an Archaeological Charter as an instrument of prevention and protection of the territory. The contributions within the volume deepen the study of the territory of Modena/ Roman Modena and paint a picture as vast as possible of the society that produced and used the mosaics. More technical texts follow, concerning the detachment, restoration and exhibition operations.
