Bernini's popularity was such that on his walks in Paris the streets were lined with admiring crowds. But things soon turned sour. Bernini presented finished designs for the east front (i.e., the all-important principal facade of the entire palace) of the Louvre, which were ultimately rejected, albeit formally not until 1667, well after his departure from Paris (indeed, the already constructed foundations for Bernini's Louvre addition were inaugurated in October 1665 in an elaborate ceremony, with both Bernini and King Louis in attendance). It is often stated in the scholarship on Bernini that his Louvre designs were turned down because Louis and his financial advisor Jean-Baptiste Colbert considered them too Italianate or too Baroque in style. In fact, as Franco Mormando points out, "aesthetics are "never" mentioned in any of . . . surviving memos" by Colbert or any of the artistic advisors at the French court. The explicit reasons for the rejections were utilitarian, namely, on the level of physical security and comfort (e.g., location of the latrines). It is also indisputable that there was an interpersonal conflict between Bernini and the young French king, each one feeling insufficiently respected by the other. Though his design for the Louvre went unbuilt, it circulated widely throughout Europe by means of engravings and its direct influence can be seen in subsequent stately residences such as Chatsworth House, Derbyshire, England, seat of the Dukes of Devonshire.
