In his time, Renaissance master Leonardo da Vinci sought to translate his artistic visions into teachable text and drawings. Later, his work was compiled by a student and released as da Vinci's Treatise on Painting. Different countries and different generations received slightly different versions of the texts. Now, more than 40 manuscripts are available for study and comparison through a new UVA archive. The da Vinci database includes materials from libraries in Florence and Venice, Naples and Rome, and offers what archive creator and art history professor Francesca Fiorani calls "the pattern of diffusion of da Vinci's legacy."
