Despite spending his whole career as a fencing master in Italy, particularly Florence, Ferdinando Masiello had influence that spread well beyond the borders of his homeland. Aside from his colossal fencing treatise of 1887, this influence also took place through his students, perhaps the most decorated of which being Luigi Sestini of Florence.
Sestini left Italy in the 1890s and founded a club in Berlin, quickly establishing himself as the foremost expert on Italian fencing in Germany, and soon he was rubbing elbows with various military officers, eventually leading to Masiello's method (through Sestini) to be adopted by the German army.
Today I present the Luigi Sestini's treatise Das Fechten mit Florett und Säbel ('Fencing with foil and sabre'), probably published in 1903 (no date of publication listed in the book).

The 247-page treatise is largely a German translation of Masiello's 1887 treatise, with new illustrations and slight changes 'to meet German needs and conceptions'.
In addition to Sestini's influence in Germany, his treatise and teaching method would also come to serve as the basis for the Dutch navy's fencing regulations, which was largely a simplified version of the sabre section of Sestini's treatise, using the same illustrations.
