He was probably born in Bologna. His text Opera Nova dell'Arte delle Armi (roughly equivalent to The New Text on the Art of Arms) was published in 1536 in Modena, dedicated to Count Rangoni, then reprinted several times all the way into the next century. It is considered one of the most important works about fencing in the 16th century. It exemplifies theory, sequences and techniques about combat with different weapons, such as: Bologna (IPA , from Latin Bononia, Bulåggna in the local dialect) is the capital city of Emilia-Romagna in northern Italy, in the Pianura Padana, between the Po River and the Apennines, exactly between the Reno River and the Sàvena River. ...

He also includes a fairly comprehensive treatise on judicial dueling custom in Italy. The text was originally embellished with woodcuts, while after the 1568 edition, copperplate engravings were used.

Achille Marozzo states he studied swordsmanship under Guido Antonio Di Luca, about whom he says that "as many warriors came out of his school as did out of the Trojan horse." Later Bolognese fencing masters such as Viggiani and Dall'Agocchie may have been influenced by his work, if not directly studied under him.

Today, Marozzo's work is being studied and researched by several historical fencing groups in the US and abroad.
