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.
Ferdinando Sanfelice
Sanfelice was known primarily for temporary displays and his secular architecture. The former involved displays such as those set up for royal visits and births as well as for religious celebrations; the latter included a large number of family dwellings in Naples, including his own Palazzo Sanfelice, built between 1723 and 1728, and the Palazzo Serra di Cassano, finished around 1730. Most notable in Sanfelice's architecture are the staircases; rather than being incidental features set off to the side of a courtyard, he gave them central and prominent positions so that they became important architectural features in their own right, often as double staircases.
