In fourteenth-century Italy, literacy became accessible to a significantly larger portion of the lay population (allegedly between 60 and 80 percent in Florence) and provided a crucial means for the vernacularization and secularization of learning, and for the democratization of citizenship. Dante Alighieri's education and oeuvre sit squarely at the heart of this historical and cultural transition and provide an ideal case study for investigating the impact of Latin education on the consolidation of autonomous vernacular literature in the Middle Ages, a fascinating and still largely unexamined phenomenon. On the basis of manuscript and archival evidence, Gianferrari reconstructs the contents, practice, and readings of Latin instruction in the urban schools of fourteenth-century Florence. It also shows Dante's continuous engagement with this culture of teaching in his poetics, thus revealing his contribution to the expansion of vernacular literacy and education. The book argues that to achieve his unprecedented position of authority as a vernacular intellectual, Dante conceived his poetic works as an alternative educational program for laypeople, who could read and write in the vernacular but had little or no proficiency in Latin. By reconstructing the culture of literacy shared by Dante and his lay readers, Dante's Education shifts critical attention from his legacy as Italy's national poet, and a "great books" author in the Western canon, to his experience as a marginal intellectual engaged in advancing a marginal culture.
