Girolamo Muzio (1496-1576) was an Italian author who worked in many important Italian courts. He wrote poetry and treatises, and he advocated for the use of Italian over Latin. He is also known for his discourses criticizing Protestant reformers such as Pier Paolo Vergerio in Le Vergeriane and his treatises on marriage such as Avvertimenti Morali.
