Imitate this action with your own body, step forward briskly with a swinging stride and at the same time swing your arms and torso. If you feel the exhilaration of the action as I think you will, you will realise that it is the wonderful way in which Millet has suggested this contrast of the swing, that makes the action of the figure so stirring. By the contrast of its lines, it expresses energy; by the contrast of swing, so free, so rhythmic, so vigorous, it lifts us to enthusiasm.
