As Vasari's Vite was famously weaker on Venetian painters than Florentine ones, Ridolfi remains an important source for Venetian painting between the beginning of the Renaissance and his own day, although his accuracy is often doubted, and many of his numerous attributions, especially to Giorgione, are no longer accepted:"...the enormous number of paintings attributed to Giorgione by Ridolfi gravely weakens his authority".
One purpose of his work was to supply a corrective to Vasari, and just as Vasari ascribes all progress in art to Florentines, Ridolfi attempts something similar for the Venetian tradition, with its closer connection to Byzantine art. He was well educated in the classics, and his style is much given to rhetorical flourishes, classical comparisons and references to poetry, whilst rather lacking Vasari's talent for telling anecdote. He approached the larger lives in a scholarly fashion, and quoted many documents, often now vanished, that remain invaluable to art historians. His work gives great insight into the way art was seen in his own day, as well as during the lives of his subjects.
