In 1698, a fencing master Bondi di Mazo published a book called "La spada maestra di me, Bondi di Mazo da Venetia: Libro dove si trattano i vantaggi della nobilissima professione della scherma si del caminare, girare, & ritararri, come del ferire sicuramente, e difendersi". (The Masterly Sword, by Me, Bondi di Mazo from Venice: A Book wherein Are Treated the Benefits of the Most Noble Profession of Fencing, in the Advancing, Turning, and Retreating, as well as How to Strike with Certainty, and Defend Oneself).Nothing is known about this man, but judging by his name he was a Jew - Bondi was a popular Jewish first name and Mazo or Mayo or Majo was a Jewish family living in Venice. A Venetian Rabbi named Mose Majo passed away in Venice in 1709. I am attaching some title pages from the book. If anyone has any details about Bondi di Mazo or his family, please share them.
