Simplicity, when so very inartificial as to seem to evade the difficulties of art, is a very suspicious virtue.
I do not, however, wish to degrade simplicity from the high estimation in which it has been ever justly held. It is our barrier against that great enemy to truth and nature, affectation, which is ever clinging to the pencil, and ready to drop in and poison everything it touches.
Our love and affection to simplicity proceeds in a great measure from our aversion to every kind of affectation. There is likewise another reason why so much stress is laid upon this virtue; the propensity which artists have to fall into the contrary extreme; we therefore set a guard on that side which is most assailable. When a young artist is first told, that his composition and his attitudes must be contrasted, that he must turn the head contrary to the position of the body, in order to produce grace and animation; that his outline must be undulating, and swelling, to give grandeur; and that the eye must be gratified with a variety of colours; when he is told this, with certain animating words, of spirit, dignity, energy, grace, greatness of style, and brilliancy of tints, he becomes suddenly vain of his newly acquired knowledge, and never thinks he can carry those rules too far. It is then that the aid of simplicity ought to be called in, to correct the exuberance of youthful ardour.
The same may be said in regard to colouring, which in its pre-eminence is particularly applied to flesh. An artist, in his first essay of imitating nature, would make the whole mass of one colour, as the oldest painters did; till he is taught to observe not only the variety of tints, which are in the object itself, but the differences produced by the gradual decline of light to shadow: he then immediately puts his instruction in practice, and introduces a variety of distinct colours. He must then be again corrected and told, that though there is this variety, yet the effect of the whole upon the eye must have the union and simplicity of the colouring of nature.
And here we may observe that the progress of an individual student bears a great resemblance to the progress and advancement of the art itself. Want of simplicity would probably be not one of the defects of an artist who had studied nature only, as it was not of the old masters, who lived in the time preceding the great art of painting; on the contrary, their works are too simple and too inartificial.
The art in its infancy, like the first work of a student, was dry, hard, and simple. But this kind of barbarous simplicity would be better named penury, as it proceeds from mere want; from want of knowledge, want of resources, want of abilities to be otherwise: their simplicity was the offspring, not of choice, but necessity.
In the second stage they were sensible of this poverty; and those who were the most sensible of the want were the best judges of the measure of the supply. There were painters who emerged from poverty without falling into luxury. Their success induced others, who probably never would of themselves have had strength of mind to discover the original defect, to endeavour at the remedy by an abuse; and they ran into the contrary extreme. But however they may have strayed, we cannot recommend to them to return to that simplicity which they have justly quitted; but to deal out their abundance with a more sparing hand, with that dignity which makes no parade, either of its riches, or of its art. It is not easy to give a rule which may serve to fix this just and correct medium; because when we may have fixed, or nearly fixed the middle point, taken as a general principle, circumstances may oblige us to depart from it, either on the side of simplicity or on that of variety and decoration.
I thought it necessary in a former discourse, speaking of the difference of the sublime and ornamental style of painting,—in order to excite your attention to the more manly, noble, and dignified manner, to leave perhaps an impression too contemptuous of those ornamental parts of our art, for which many have valued themselves, and many works are much valued and esteemed.
I said then, what I thought it was right at that time to say; I supposed the disposition of young men more inclinable to splendid negligence, than perseverance in laborious application to acquire correctness; and therefore did as we do in making what is crooked straight, by bending it the contrary way, in order that it may remain straight at last.
For this purpose, then, and to correct excess or neglect of any kind, we may here add, that it is not enough that a work be learned; it must be pleasing: the painter must add grace to strength, if he desires to secure the first impression in his favour. Our taste has a kind of sensuality about it, as well as a love of the sublime; both these qualities of the mind are to have their proper consequence, as far as they do not counteract each other; for that is the grand error which much care ought to be taken to avoid.
