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
After Bramante's death in 1514, Raphael was named architect of the new St Peter's. Most of his work there was altered or demolished after his death and the acceptance of Michelangelo's design, but a few drawings have survived. It appears his designs would have made the church a good deal gloomier than the final design, with massive piers all the way down the nave, "like an alley" according to a critical posthumous analysis by Antonio da Sangallo the Younger. It would perhaps have resembled the temple in the background of "The Expulsion of Heliodorus from the Temple".
