La dinamica dei confini orientali dell’Italia romana: fonti antiche e riletture moderne.

The state of knowledge and the still open problems concerning the borders of Roman Italy are presented, pointing out that their evolution is known in broad outline, while some details concerning the positioning of the borders and the absolute chronology remain unresolved. In addition, some examples are presented of how the borders of Roman times, whether real (such as the Augustan border at Arsia) or presumed (such as the praetentura Alpium or the claustra Alpium Iuliarum) have been evoked on several occasions during the negotiations to define the borders of modern states.
