ROMAN PORTS IN THE LOWER TIBER VALLEY: COMPUTATIONAL APPROACHES TO REASSESS ROME'S PORT SYSTEM

This paper presents an innovative study of the port system of Rome in Imperial times through the application of an integrated approach to both archaeological analysis and material evidence. Specifically, it seeks to provide a more complete contextualization and understanding of the port system of Rome by focusing on the exploration of the physical geography of the river Tiber and its transformations in connection with the organization of the port system between the late first century BC and early third century AD. Methodologically, this study is based on the compilation, re-evaluation and analysis of published archaeological and geoarchaeological data and on the application of modelling and simulations techniques within a GIS environment. These foundations and means allow us to reconstruct the development of the river Tiber's historical course in antiquity and its impact on specific organizational aspects of Rome's port system. In this sense, this study provides new insights and avenues of research (applicable to other geographical areas and periods of time) to evaluate the system's changing capacity for transport and the potential existence of a signalling system, in contrast to previous hypotheses on the organization of river traffic along the Tiber.

THE PIRAEUS FROM 86 BC TO LATE ANTIQUITY: CONTINUITY AND CHANGE IN THE LANDSCAPE, FUNCTION AND ECONOMY OF THE PORT OF ROMAN ATHENS

Modern perceptions of the ancient Piraeus have been monopolised by the urban image and function of the port as the naval stronghold of Classical Athens. Existing scholarship so far has tended to consider the post-Classical centuries, especially the era following the sack of the port in 86bcby the Romans, as a period of decline. Such preconceptions, based on largely superficial readings of a few ancient literary texts and a near-total disregard of the material evidence, have created a distorted image of the Piraeus and its significance in the Roman period. Drawing upon textual sources as well as archaeological evidence, this paper explores the changing nature of urban settlement, maritime functions and the economy of the port from the time of its destruction in 86bcto around the sixth centuryad. Particular emphasis is placed on a re-examination of the existing evidence from rescue excavations conducted by the Greek Archaeological Service as they relate to the topography of the Roman port and its long-term evolution. This combined study offers a more complex picture of the infrastructure, urban image and operational capability of the port during the Roman period than was hitherto possible. It also permits a more balanced understanding of the port's function at local, regional and provincial levels, and thus enables comparisons with other Roman ports in the Aegean and the rest of the Mediterranean.
