Although he received no personal commissions from Innocent or the Pamphilj family in the early years of the new papacy, Bernini did not lose his former positions granted to him by previous popes. Innocent X maintained Bernini in all of the official roles given to him by Urban, including that of chief Architect of St. Peter's. Under Bernini's design and direction, work continued on decorating the massive, recently completed but still entirely unadorned nave of St. Peter's, with the addition of an elaborate multi-colored marble flooring, marble facing on the walls and pilasters, and scores of stuccoed statues and reliefs. It is not without reason that Pope Alexander VII once quipped, 'If one were to remove from Saint Peter's everything that had been made by the Cavalier Bernini, that temple would be stripped bare.' Indeed, given all of his many and various works within the basilica over several decades, it is to Bernini that is due the lion's share of responsibility for the final and enduring aesthetic appearance and emotional impact of St. Peter's. He was also allowed to continue to work on Urban VIII's tomb, despite Innocent's antipathy for the Barberini. A few months after completing Urban's tomb, in 1648 Bernini won, in controversial circumstances, the Pamphilj commission for the prestigious Four Rivers Fountain on Piazza Navona, marking the end of his disgrace and the beginning a yet another glorious chapter in his life.
