The volume presents an overall view of the Venice Lagoon (Italy) focusing on the archaeological area of the Treporti-San Felice Channel and the ancient city of Altinum. Starting from the archaeological traces submerged detected in the analysis and re-elaboration of data through new methods and technologies, the book represents an opportunity to consider various aspects. The volume discusses geo-environmental transformations throughout the centuries, ancient settlements and road systems, and the connections between ancient and contemporary times through architectonic projects and virtual reconstructions. The book also offers some considerations about relevant Greek and Latin texts and the Classical Tradition, promoting a 'kaleidoscopic' vision and understanding of the origin of Venice and of the possible scenarios for the city in the near and distant future.
