Using his influence as Colbert's administrative aide, in April 1667 he was able to get his brother, Claude Perrault, appointed to a committee of three, the Petit Conseil, also including Louis Le Vau and Charles Le Brun, who designed the new section of the Louvre, the Colonnade, built between 1667 and 1674, to be overseen by Colbert. The design was chosen over designs by Gian Lorenzo Bernini (with whom, as Perrault recounts in his "Memoirs," he had stormy relations while the Italian artist was in residence at Louis's court in 1665) and François Mansart. One of the factors leading to this choice included the fear of high costs, and second was the personal antagonism between Bernini and leading members of Louis' court, including Colbert and Perrault; King Louis himself maintained a public air of benevolence towards Bernini, ordering the issuing of a royal bronze portrait medal in honor of the artist in 1674. As Perrault further describes in his "Memoirs", however, the king harbored private resentment at Bernini's displays of arrogance. The king was so displeased with Bernini's equestrian statue of him that he ordered it to be destroyed; however, his courtiers prevailed upon him to have it redone instead, with a head depicting the Roman hero Marcus Curtius.
