Il comprensorio della catacomba di San Callisto tra la via Appia e la via Ardeatina (Roma) alla luce delle indagini geofisiche estensive

The paper presents and discusses results from the integration of various methods of geophysical prospection on the plateau between the Via Appia and the Via Ardeatina on the ancient suburb of Rome. The use of large-scale magnetometry, georadar and electromagnetic survey in an area of particularly dense archaeological remains is a highly effective method- ology for revealing important information on previously unknown archaeological features. Of particular interest in this case is the comparison between geophysical data and the results of previous excavations, and newly-targeted test investigations that suggest the survival of the documented but previously undiscovered basilica of Pope Damasus as well as unknown catacomb tunnels at San Callisto and elsewhere on the plateau.
