Ingres's style was formed early in life and changed comparatively little. His earliest drawings, such as the Portrait of a Man (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."
