Focus on Napoleon I on His Imperial Throne and explain the Reception.
At the Salon, it produced a disturbing impression on the public, due not only to Ingres's stylistic idiosyncrasies but also to his depiction of the  Carolingian imagery worn by Napoleon at his coronation. David (who finished his own The Coronation of Napoleon the following year) delivered a severe judgement, and the critics were uniformly hostile, finding fault with the strange discordances of colour, the want of sculptural relief, the chilly precision of contour, and the self-consciously archaic quality. As shown above, Chaussard (Le Pausanias Français, 1806) condemned Ingres's style as gothic (the troubadour style was beginning at this time). As art historian Marjorie Cohn has written: "At the time, art history as a scholarly enquiry was brand new. Artists and critics outdid each other in their attempts to identify, interpret, and exploit what they were just beginning to  perceive as historical stylistic developments." The Louvre, newly filled with booty seized by Napoleon in his campaigns in Belgium, the Netherlands, and Italy, provided French artists of the early nineteenth century with an unprecedented opportunity to study, compare, and copy masterworks from antiquity and from the entire history of European painting. From the beginning of his career, Ingres freely borrowed from earlier art, adopting the historical style appropriate to his subject, leading critics to charge him with plundering the past.
