[Note 13: When this lecture was delivered, I gave here some data for approximate estimates of the average value of good modern pictures of different classes; but the subject is too complicated to be adequately treated in writing, without introducing more detail than the reader will have patience for. But I may state, roughly, that prices above a hundred guineas are in general extravagant for water-colours, and above five hundred for oils. An artist almost always does wrong who puts more work than these prices will remunerate him for into any single canvas--his talent would be better employed in painting two pictures than one so elaborate. The water-colour painters also are getting into the habit of making their drawings too large, and in a measure attaching their price rather to breadth and extent of touch than to thoughtful labour. Of course marked exceptions occur here and there, as in the case of John Lewis, whose drawings are wrought with unfailing precision throughout, whatever their scale. Hardly any price can be remunerative for such work.]
103. There is, however, another point, and a still more important one, bearing on this matter of purchase, than the keeping down of prices to a rational standard. And that is, that you pay your prices into the hands of living men, and do not pour them into coffins.
For observe that, as we arrange our payment of pictures at present, no artist's work is worth half its proper value while he is alive. The moment he dies, his pictures, if they are good, reach double their former value; but, that rise of price represents simply a profit made by the intelligent dealer or purchaser on his past purchases. So that the real facts of the matter are, that the British public, spending a certain sum annually in art, determines that, of every thousand it pays, only five hundred shall go to the painter, or shall be at all concerned in the production of art; and that the other five hundred shall be paid merely as a testimonial to the intelligent dealer, who knew what to buy. Now, testimonials are very pretty and proper things, within due limits; but testimonial to the amount of a hundred per cent. on the total expenditure is not good political economy. Do not, therefore, in general, unless you see it to be necessary for its preservation, buy the picture of a dead artist. If you fear that it may be exposed to contempt or neglect, buy it; its price will then, probably, not be high: if you want to put it into a public gallery, buy it; you are sure, then, that you do not spend your money selfishly: or, if you loved the man's work while he was alive, and bought it then, buy it also now, if you can see no living work equal to it. But if you did not buy it while the man was living, never buy it after he is dead: you are then doing no good to him, and you are doing some shame to yourself. Look around you for pictures that you really like, and in buying which you can help some genius yet unperished--that is the best atonement you can make to the one you have neglected--and give to the living and struggling painter at once wages, and testimonial.
