Raphael
Raphael was enormously productive, running an unusually large workshop and, despite his death at 37, leaving a large body of work. Many of his works are found in the Vatican Palace, where the frescoed Raphael Rooms were the central, and the largest, work of his career. The best known work is "The School of Athens" in the Vatican Stanza della Segnatura. After his early years in Rome much of his work was executed by his workshop from his drawings, with considerable loss of quality. He was extremely influential in his lifetime, though outside Rome his work was mostly known from his collaborative printmaking.
Raphael
Vasari emphasises that Raphael ran a very harmonious and efficient workshop, and had extraordinary skill in smoothing over troubles and arguments with both patrons and his assistants—a contrast with the stormy pattern of Michelangelo's relationships with both. However though both Penni and Giulio were sufficiently skilled that distinguishing between their hands and that of Raphael himself is still sometimes difficult, there is no doubt that many of Raphael's later wall-paintings, and probably some of his easel paintings, are more notable for their design than their execution. Many of his portraits, if in good condition, show his brilliance in the detailed handling of paint right up to the end of his life.
