Approche géométrique des centuriations Romaines. Les nouvelles bornes du Bled Segui

Abstract

The Romans, principally interested in the practical application of Greek technical knowledge, developed geodesic surveying to a high degree and their largest known centuriation, situated in the ancient province of Africa Nova is a perfect example. Since the cadastre relies on a geometrical layout, it is possible to reconstruct the grid and try to understand its principles. We first examine the geometrical constructions that could have served for centuriation in Tunisia before proposing solutions based on new discoveries made near Chott el Fejej. We go on to study certain methods for orienting and constructing the grids which we compare with the lines plotted on site. Finally, the perspectives opened up by this geographical monument are considered from the points of view of both to find other stones in place and that of better understanding cadastral science and techniques in antiquity. © Éditions de l'EHESS.
