Gelli gives the simpler title Theorie de l'Escrime for Bertrand Lozes's 1862 manual, whereas the local shell had drifted to Theorie de l'escrime simultanee. The catalogue adopts the cleaner Gelli form unless stronger contradictory title evidence appears later.
Quality phase 653: confirmed distinct from Gomard’s 1845 La théorie de l’escrime; Thimm identifies Bertrand Lozès and the fuller title Théorie de l’escrime simultanée.
