Muzzioli was born in Modena, after his family had moved from Castelvetro.
At the age of 15 years, he began to attend the local Academy of Fine Arts of Modena, working under Antonio Simonazzi and Asioli.
At the age of seventeen (1871), years later, he gained the Poletti scholarship entitling him to four years residence in Rome studying at the Accademia di San Luca, working first under professor Podesti, and later after 1874 under professor Coghetti.
