The Lives of the Most Excellent Italian Painters, Sculptors, and Architects, from Cimabue to Our Times, or Le Vite de' più eccellenti pittori, scultori, e architettori da Cimabue insino a' tempi nostri, as it was originally known in Italian, is a series of artist biographies written by 16th-century Italian painter and architect Giorgio Vasari, which is considered "perhaps the most famous, and even today the most-read work of the older literature of art", "some of the Italian Renaissance's most influential writing on art", and "the first important book on art history". The title is often abridged to the Vite or the Lives. - Summary from Wikipedia
