Indagini multidisciplinari e ricostruzione virtuale: il caso di studio del Teatro Nord di Hierapolis di Frigia (Turchia)

Abstract

The contribution concerns the multidisciplinary research conducted on the North Theatre of Hierapolis in Phrygia (south-western Turkey), built in the 2nd cent. AD and collapsed because of an earthquake in the third quarter of the 4th cent. AD. A systematic analysis and topographical survey of the remains of the Theatre were performed, and plan of the building was integrated into the digital archaeological map of the city. These data were combined with those from the geological study of the site (characterized by landslides) and from the geophysical prospecting (magnetometry and GPR) carried out in the area of the scaena and in the space between the Theatre and the North Agora. The integration with the data acquired during field works conducted also along the Early-Byzantine city walls (where numerous marble and travertine seats of the Theatre were re-used) allowed the virtual reconstruction of the monument into the original shape of the site by means of 3D photomodelling techniques.
