It is well known that Alceo Dossena was a skilled forger of marble sculptures in the style of the Tuscan Renaissance. His activity was exposed following the scandal surrounding the case of the tomb of Maria Caterina Savelli, which was sculpted in the style of Mino da Fiesole and sold to the Boston Museum of Fine Arts. Less thoroughly researched, on the other hand, are the many medieval fakes he produced, even from early on in his career, when he was still living in the Valle Padana between Cremona and Parma. The paper focuses on the production of fake Gothic sculptures by Dossena, carved in marble, stone and wood, imitating the style of great exponents of the Italian Gothic like Benedetto Antelami, Giovanni Pisano and Giovanni di Balduccio. As well as adding some pieces to the catalogue of the well-known forger, the present article also aims to clarify the technical and semantic processes behind the production of these imitations, which have at times deceived even the most discerning scholars.
