People like Dante Alighieri

Dante Alighieri (Italian: [ˈdante aliˈɡjɛːri]; c. 1265 – 14 September 1321), probably baptized Durante di Alighiero degli Alighieri and often referred to as Dante (English: , US: ), was an Italian poet, writer and philosopher. His Divine Comedy, originally called Comedìa (modern Italian: Commedia) and later christened Divina by Giovanni Boccaccio, is widely considered one of the most important poems of the Middle Ages and the greatest literary work in the Italian language.

Dante is known for establishing the use of the vernacular in literature at a time when most poetry was written in Latin, which was accessible only to the most educated readers. His De vulgari eloquentia (On Eloquence in the Vernacular) was one of the first scholarly defenses of the vernacular. His use of the Florentine dialect for works such as The New Life (1295) and Divine Comedy helped establish the modern-day standardized Italian language. His work set a precedent that important Italian writers such as Petrarch and Boccaccio would later follow.
