Gelli later cites J. Baptiste Esches, Méthode d'escrime, Fribourg, 1848. Given the strong overlap of author form, place, and fencing context with Johann Baptist Escher's Fribourg work family, the local record keeps the secure 1833 German manual as the anchor and preserves Gelli's 1848 French-title notice as a secondary family witness rather than as a separate unverified work.
