Ancient restorations: computer-based structural approach for the identification and reinterpretation of the Medracen’s constructive sequence

This paper addresses the importance of a structural approach for identifying and interpreting building chronology, as well establishment historical stratigraphy. Through analyses, carried out on oldest extant royal mausoleum in North Africa, Medracen (4th-3rd century BC), located eastern Algeria, it has been possible to identify sequences characteristics; reinterpretation its constructive sequence within specific context was also suggested. A static linear Finite Element Method (FEM) analysis performed simplified 3D model conceived with solid elements assess behaviour structure under effect self-weight identify, consequently, construction sequence. The equilibrium effective structure’s geometry. Results show that Medracen’s ancient restoration strengthening intervention strategy had symbolic aim related function funerary building. Restoration works, consisting repairing parts adding an external cladding, whole architectural entity, contributed reducing tensile stress, therefore, stabilizing inner core. Besides, this same action means Numidian elite transform monumental burial (sepulchrum) into monument (monumentum) cultural significance likely convey socio-political messages relating power sovereignty. Therefore, we can speak “evolutionary restoration” reflects ambitions become part Mediterranean orbit.
