Seven Discourses on Art | Page 8

will discover, at last, the manner of handling, the artifices of contrast, glazing, and other expedients, by which good colourists have raised the value of their tints, and by which nature has been so happily imitated.
I must inform you, however, that old pictures deservedly celebrated for their colouring are often so changed by dirt and varnish, that we ought not to wonder if they do not appear equal to their reputation in the eyes of unexperienced painters, or young students. An artist whose judgment is matured by long observation, considers rather what the picture once was, than what it is at present. He has acquired a power by habit of seeing the brilliancy of tints through the cloud by which it is obscured. An exact imitation, therefore, of those pictures, is likely to fill the student's mind with false opinions, and to send him back a colourist of his own formation, with ideas equally remote from nature and from art, from the genuine practice of the masters and the real appearances of things.
Following these rules, and using these precautions, when you have clearly and distinctly learned in what good colouring consists, you cannot do better than have recourse to nature herself, who is always at hand, and in comparison of whose true splendour the best coloured pictures are but faint and feeble.
However, as the practice of copying is not entirely to be excluded, since the mechanical practice of painting is learned in some measure by it, let those choice parts only be selected which have recommended the work to notice. If its excellence consists in its general effect, it would be proper to make slight sketches of the machinery and general management of the picture. Those sketches should be kept always by you for the regulation of your style. Instead of copying the touches of those great masters, copy only their conceptions. Instead of treading in their footsteps, endeavour only to keep the same road. Labour to invent on their general principles and way of thinking. Possess yourself with their spirit. Consider with yourself how a Michael Angelo or a Raffaelle would have treated this subject: and work yourself into a belief that your picture is to be seen and criticised by them when completed. Even an attempt of this kind will rouse your powers.
But as mere enthusiasm will carry you but a little way, let me recommend a practice that may be equivalent, and will perhaps more efficaciously contribute to your advancement, than even the verbal corrections of those masters themselves, could they be obtained. What I would propose is, that you should enter into a kind of competition, by painting a similar subject, and making a companion to any picture that you consider as a model. After you have finished your work, place it near the model, and compare them carefully together. You will then not only see, but feel your own deficiencies more sensibly than by precepts, or any other means of instruction. The true principles of painting will mingle with your thoughts. Ideas thus fixed by sensible objects, will be certain and definitive; and sinking deep into the mind, will not only be more just, but more lasting than those presented to you by precepts only: which will, always be fleeting, variable, and undetermined.
This method of comparing your own efforts with those of some great master, is indeed a severe and mortifying task, to which none will submit, but such as have great views, with fortitude sufficient to forego the gratifications of present vanity for future honour. When the student has succeeded in some measure to his own satisfaction, and has felicitated himself on his success, to go voluntarily to a tribunal where he knows his vanity must be humbled, and all self-approbation must vanish, requires not only great resolution, but great humility. To him, however, who has the Ambition to be a real master, the solid satisfaction which proceeds from a consciousness of his advancement (of which seeing his own faults is the first step) will very abundantly compensate for the mortification of present disappointment. There is, besides, this alleviating circumstance. Every discovery he makes, every acquisition of knowledge he attains, seems to proceed from his own sagacity; and thus he acquires a confidence in himself sufficient to keep up the resolution of perseverance.
We all must have experienced how lazily, and consequently how ineffectually, instruction is received when forced upon the mind by others. Few have been taught to any purpose who have not been their own teachers. We prefer those instructions which we have given ourselves, from our affection to the instructor; and they are more effectual, from being received into the mind at the very time when it is most open and eager to receive them.
With respect to the pictures that you are
