The Venetian Painters of the Renaissance by Bernard Berenson,the American art historian specializing in the Renaissance. His book The Italian Painters of the Renaissance was an international success. In this respect Berenson's influence was enormous, while his 5% commission made him a wealthy man. (According to Charles Hope, he "had a financial interest in many works...an arrangement that Berenson chose to keep private.") Starting with his The Venetian Painters of the Renaissance with an Index to their Works (1894), his mix of connoisseurship and systematic approach proved immensely successful.
