La rue au fil du temps. L'exemple du decumanus occidental à Ostie

The western section of the Ostia decumanus offers a landscape that is deeply marked by the reshaping and restoration work carried out following the excavations conducted by Guido Calza between 1938 and 1942, so much so that the scenography set up at that time conceals from the layman's eye the complexity of the urban evolution of this area. Only the didactic area at the foot of the Domus sul decumano (III, II, 3) still bears witness to the complexity of the evolution of the western districts of Ostia. This survey shows unambiguously that this area underwent several major urban phases from its creation during the Republican period to its abandonment at the end of Antiquity. Each of these phases is characterised by a different urban landscape, which this presentation proposes to highlight through the analysis of the façades that make up the volume of this street, in order to successively draw the contours of this space in the Severian period, at the end of Hadrian's reign, and then in the Augustan period. To this end, this process will be based on the documentation of the ancient excavations kept at the Parco Archeologico di Ostia Antica. These documents will first of all make it possible to deconstruct the archaeological landscape as we see it today and to reconstruct the archaeological landscape as it was before the remodelling carried out in 1938-42
