Heavens of Knowledge: The Order of Sciences in Dante’s Convivio

The essay focuses on Dante’s divisio scientiae presented in the second book of his Convivio. As a first step, it offers a fresh reading of Dante’s description of knowledge and the cosmos, emphasizing its deeply visual nature. The article then presents an overview of the Medieval tradition of the divisio scientiae, culminating with divisions that are geographically and chronologically close to Dante’s Florence. In relation to Brunetto Latini’s Rettorica and Tresor, new evidence is provided to elucidate his peculiar division of logic. Ultimately, Dante’s divisio and its objectives are reassessed in light of their historical background, underscoring their cosmological and totalizing scope. Adopting an interdisciplinary approach, the findings consider cognitive practices, such as diagrams, and examine a wide array of sources within their historical and institutional context, highlighting their transmission and dissemination.
