Given the standings of the two men, the painting was received in both social and political terms. A number of writers mentioned Bertin's eventful career, in tones that were, according to art historian Andrew Carrington Shelton, either "bitingly sarcastic [or] fawningly reverential". There were many satirical reproductions and pointed editorials in the following years. Aware of Bertin's support of the July Monarchy, writers at the La Gazette de France viewed the portrait as the epitome of the "opportunism and cynicism" of the new regime. Their anonymous critic excitedly wondered "what bitter irony it expresses, what hardened skepticism, sarcasm and ... pronounced cynicism".Several critics mentioned Bertin's hands. Twentieth-century art historian Albert Boime described them as "powerful, vulturine ... grasping his thighs in a gesture ... projecting ... enormous strength controlled". Some contemporary critics were not so kind. The photographer and critic Félix Tournachon was harshly critical, and disparaged what he saw as a "fantastical bundle of flesh ... under which, instead of bones and muscles, there can only be intestines – this flatulent hand, the rumbling of which I can hear!" Bertin's hands made a different impression on the critic F. de Lagenevais, who remarked: "A mediocre artist would have modified them, he would have replaced those swollen joints with the cylindrical fingers of the first handy model; but by this single alteration he would have changed the expression of the whole personality ... the energetic and mighty nature".The work's realism attracted a large amount of commentary when it was first exhibited. Some saw it as an affront to Romanticism, others said that its small details not only showed an acute likeness, but built a psychological profile of the sitter. Art historian Geraldine Pelles sees Bertin as "at once intense, suspicious, and aggressive". She notes that there is a certain amount of projection of the artist's personality and recalls Théophile Silvestre's description of Ingres; "There he was squarely seated in an armchair, motionless as an Egyptian god carved of granite, his hands stretched wide over parallel knees, his torso stiff, his head haughty". Some compared it to Balthasar Denner, a German realist painter influenced by Jan van Eyck. Denner, in the words of Ingres scholar Robert Rosenblum, "specialised in recording every last line on the faces of aged men and women, and even reflections of windows in their eyes." The comparison was made by Ingres' admirers and detractors alike. In 1833, Louis de Maynard of the Collège-lycée Ampère, writing in the influential L'Europe littéraire, dismissed Denner as a weak painter concerned with hyperrealistic "curiosities", and said that both he and Ingres fell short of the "sublime productions of Ingres' self-proclaimed hero, Raphael."The following year Ingres sought to capitalise on the success of his Bertin portrait. He showed his ambitious history painting The Martyrdom of Saint Symphorian at the 1834 Salon, but it was harshly criticised; even Ingres' admirers offered only faint praise. Offended and frustrated, Ingres declared he would disown the Salon, abandon his residence in Paris for Rome, and relinquish all current positions, ending his role in public life. This petulance was not to last.Bertin bequeathed the portrait to his daughter Louise (1805–1877) on his death. She passed it to her niece Marie-Louise-Sophie Bertin (1836–1893) wife of Jules Bapst, a later director of the Journal des débats. They bequeathed it to their niece Cécile Bapst, its last private owner. In 1897 Cécile sold it to the Musée du Louvre for 80,000 francs.
