This integration resulted in a more useful and complete scientifc representation enabling us to identify and communicate the essence of the monument itself since the information about its form, geometry and proportions were thus combined with immaterial aspects such as the color and the efect produced by the light on the materials. INTRODUCTION The present study was carried out as part of a re- search conducted at the archaeological site of Petra in Jordan by a multidisciplinary team made up of Italian and Jordanian archaeologists and architects competent in the various disciplines making up the scientific fields of drawing, survey, history of architecture and archeology. The scholars worked together, integrating skills and competences with the aim of following a path of knowledge to fully understand the characteristics and peculiarities of the archaeological artifacts [1]. The comparison and exchange of different experiences has been a great wealth both from the cultural and the scientific point of view: in fact, the researchers in the working group have been able to directly compare each other “on the field”, thus becoming able to control and monitor the working process in relation both to Emanuela Chiavoni Università Sapienza Roma, Italy
