This volume, edited by S. Maggi and ME Gorrini, collects the reports and posters presented at the “Casteggio e l'antico. 25 years of archaeological studies and research in the province of Pavia ”, held on 19 October 2013 at the Palazzo Certosa Cantù, seat of the Casteggio Museum. The volume presents the new data on the archaeological research carried out in Pavia and in the surrounding areas in the last twenty-five years: research that covers a chronological period ranging from Prehistory to the Middle Ages. The museums present in the area are illustrated by Maria Grazia Diani ( Directorate General for Education, Training, Culture of the Lombardy Region); Valentina Dezza, Raffaella Fasani and Laura Vecchi underline in their contribution the importance of museum teaching carried out at the Civic Archaeological Museum of Casteggio and Oltrepò Pavese, thanks also to the collaboration with CRIDACT (Interdepartmental Research Center for the Didactics of Classical Archeology and Ancient Technologies) of the University of Pavia. The professor. Pierluigi Tozzi, emeritus of the University of Pavia and leading expert in ancient topography, thanks to archival research and careful analysis of aerial photography, endorses the legend of the foundation of Pavia located in Opicino de Canistris about the first headquarters of Santa Sofia city of Torre d'Isola. The research of Prof. Tozzi has given way to a surface archaeological investigation project conducted by ME Gorrini, whose contribution in these acts deals with the aspect of the sacred of ticinum, putting forward some hypotheses of topographical identification of Templar buildings. It concerns ticinum also the intervention of Stefano Maggi, who proposes new chronological hypotheses for the dedications and for the statues of the eastern arch door of the Roman city. Mirella Robino and Stefano Rocchi present two sarcophagi from the Pavia area: the first suggests an epigraphic reading of an unpublished now in Vespolate; the second discusses the provenance of the sarcophagus of Luxurius (Suppl. It. 871) and presents an unpublished epigraphic preserved in the Civic Museums of Pavia. Wide prominence is given to the new archaeological excavations, and to the relative data, by the province of Pavia: Rosanina Invernizzi illustrates in this volume the recent archaeological investigations in the Oltrepò Pavese; Giorgio Baratti presents the account of the excavation site, opened since 1994, of the University of Milan at the Castelliere del Guardamonte, which occupies the summit and southern slope of Monte Valassa, on the border between the provinces of Pavia and Alessandria. Silvia Lusuardi Siena, Elena Dellù and Simona Sironi present the excavations opened in 2011 by the Catholic University of the Sacred Heart in Monte Pico, in the Ardivestra valley, with reference to medieval settlements. Luigi Schiavi critically examines the dating hypotheses of the early medieval crypt of the Pavia church of San Giovanni Domnarum.
Marica Venturino Gambari, Margherita Roncaglio, Melania Cazzulo and Francesco Scarrone analyze the phases of occupation from prehistoric times to the Middle Ages of the Pontecurone area, near important river routes at the outlet in the plain of the Curone and Grue valleys. In the proto-historical context, Silvia Paltineri proposes an accurate analysis of the findings of the Pavia area, also through the re-reading of archive data, while Lucia Mordeglia focuses on the Zavatterello site, framing it in the proto-history of the Oltrepò Pavese. As regards the second section of the volume, it groups together the contributions of young scholars developed by posters presented at the Conference.
