Burial architecture. 3D dissemination study for a selection of Byzantine graves

The former polis of Tall-as-Sin (in the current province of Deir ez-Zor, Syria) grew considerably during Justinian's reign in the 6 th century AD. Its cemetery, outside the walls, presents an extraordinary Byzantine necropolis, where 163 hypogea graves were documented, thanks to recent archaeological campaigns financed by the Ministry of Culture (“PAMES-Sirio Euphrates Middle Archaeological Project”). This paper presents the research for obtaining 3D models of graves, selected in the cemetery, by combining information (obtained from planimetric and photographic surveys of the site) with taxonomic features (types of arcosolia, vaults, accesses, stairways...). The 3D modelling process is carried out using data collected during the survey of the graves. These data are then used to restore the surfaces which cover the burial chambers dug out in the ground. The modelling technique was based on generating surfaces, incorporating the different sections and profiles obtained during the data collection phase. The surfaces generated enclose the volume of the dug-out space so that the definitive grave models were obtained using a simple Boolean operation, removing these volumes from a prism-shaped piece representing a portion of the land, thus emptying the interior. The result has provided a reliable and rigorous graphic basis for the design and printing of 3D models, contributing to the dissemination of the exhibition called "A retrospective on five years of archaeological activities in Syria".
