Painting is not, like writing, what is properly understood by a sedentary employment. It requires not indeed a strong, but a continued and steady exertion of muscular power. The precision and delicacy of the manual operation makes up for the want of vehemence,—as to balance himself for any time in the same position the rope-dancer must strain every nerve. Painting for a whole morning gives one as excellent an appetite for one’s dinner, as old Abraham Tucker acquired for his by riding over Banstead Downs. It is related of Sir Joshua Reynolds, that ‘he took no other exercise than what he used in his painting-room,’—the writer means, in walking backwards and forwards to look at his picture; but the act of painting itself, of laying on the colours in the proper place, and proper quantity, was a much harder exercise than this alternate receding from and returning to the picture. This last would be rather a relaxation and relief than an effort. It is not to be wondered at, that an artist like Sir Joshua, who delighted so much in the sensual and practical part of his art, should have found himself at a considerable loss when the decay of his sight precluded him, for the last year or two of his life, from the following up of his profession,—‘the source,’ according to his own remark, ‘of thirty years uninterrupted enjoyment and prosperity to him.’ It is only those who never think at all, or else who have accustomed themselves to brood incessantly on abstract ideas, that never feel _ennui_.
