reworking the painting as a tondo, Ingres signed and dated it in 1862, although he made additional revisions in 1863. The painting was eventually purchased by a Turkish diplomat, Khalid Bey, who owned a large collection of nudes and erotic art, including several paintings by Courbet. The painting continued to cause a scandal long after Ingres was dead. It was initially offered to the Louvre in 1907, but was rejected, before being given to the Louvre in 1911. Ingres died of pneumonia on 14 January 1867, at the age of eighty-six, in his apartment on the Quai Voltaire in Paris. He is interred in the Père Lachaise Cemetery in Paris with a tomb sculpted by his student Jean-Marie Bonnassieux. The contents of his studio, including a number of major paintings, over 4000 drawings, and his violin, were bequeathed by the artist to the city museum of Montauban, now known as the Musée Ingres. Style Ingres's style was formed early in life and changed comparatively little. His earliest drawings, such as the Portrait of a Man (or Portrait of an unknown, 3 July 1797, now in the Louvre) already show a suavity of outline and an extraordinary control of the parallel hatchings which model the forms. From the first, his paintings are characterized by a firmness of outline reflecting his often-quoted conviction that "drawing is the probity of art". He believed colour to be no more than an accessory to drawing, explaining: "Drawing is not just reproducing contours, it is not just the line; drawing is also the expression, the inner form, the composition, the modelling. See what is left after that. Drawing is seven eighths of what makes up painting." The art historian Jean Clay said Ingres "proceeded always from certitude to certitude, with the result that even his freest sketches reveal the same kind of execution as that found in the final works." In depicting the human body he disregarded rules of anatomy—which he termed a "dreadful science that I cannot think of without disgust"—in his quest for a sinuous arabesque. Abhorring the visible brushstroke, Ingres made no recourse to the shifting effects of colour and light on which the Romantic school depended; he preferred local colours only faintly modelled in light by half tones. "Ce que l'on sait," he would repeat, "il faut le savoir l'épée à la main." ("Whatever you know, you must know it with sword
