Art in its perfection is not ostentatious; it lies hid, and works its effect, itself unseen. It is the proper study and labour of an artist to uncover and find out the latent cause of conspicuous beauties, and from thence form principles of his own conduct: such an examination is a continual exertion of the mind; as great, perhaps, as that of the artist whose works he is thus studying.

The sagacious imitator does not content himself with merely remarking what distinguishes the different manner or genius of each master; he enters into the contrivance in the composition how the masses of lights are disposed, the means by which the effect is produced, how artfully some parts are lost in the ground, others boldly relieved, and how all these are mutually altered and interchanged according to the reason and scheme of the work. He admires not the harmony of colouring alone, but examines by what artifice one colour is a foil to its neighbour. He looks close into the tints, examines of what colours they are composed, till he has formed clear and distinct ideas, and has learned to see in what harmony and good colouring consists. What is learned in this manner from the works of others, becomes really our own, sinks deep, and is never forgotten; nay, it is by seizing on this clue that we proceed forward, and get further and further in enlarging the principles and improving the practice of our art.

There can be no doubt, but the art is better learnt from the works themselves, than from the precepts which are formed upon those works; but if it is difficult to choose proper models for imitation, it requires no less circumspection to separate and distinguish what in those models we ought to imitate.

I cannot avoid mentioning here, though it is not my intention at present to enter into the art and method of study, an error which students are too apt to fall into. He that is forming himself, must look with great caution and wariness on those peculiarities, or prominent parts, which at first force themselves upon view; and are the marks, or what is commonly called the manner, by which that individual artist is distinguished.

Peculiar marks, I hold to be, generally, if not always, defects; however difficult it may be wholly to escape them.

Peculiarities in the works of art are like those in the human figure: it is by them that we are cognisable and distinguished one from another, but they are always so many blemishes; which, however, both in real life and in painting, cease to appear deformities, to those who have them continually before their eyes. In the works of art, even the most enlightened mind, when warmed by beauties of the highest kind, will by degrees find a repugnance within him to acknowledge any defects; nay, his enthusiasm will carry him so far, as to transform them into beauties, and objects of imitation.

It must be acknowledged, that a peculiarity of style, either from its novelty, or by seeming to proceed from a peculiar turn of mind, often escapes blame; on the contrary, it is sometimes striking and pleasing: but this it is a vain labour to endeavour to imitate; because novelty and peculiarity being its only merit, when it ceases to be new, it ceases to have value.

A manner therefore being a defect, and every painter, however excellent, having a manner, it seems to follow, that all kinds of faults, as well as beauties, may be learned under the sanction of the greatest authorities. Even the great name of Michael Angelo may be used, to keep in countenance a deficiency or rather neglect of colouring, and every other ornamental part of the art. If the young student is dry and hard, Poussin is the same. If his work has a careless and unfinished air, he has most of the Venetian school to support him. If he makes no selection of objects, but takes individual nature just as he finds it, he is like Rembrandt. If he is incorrect in the proportions of his figures, Correggio was likewise incorrect. If his colours are not blended and united, Rubens was equally crude. In short, there is no defect that may not be excused, if it is a sufficient excuse that it can be imputed to considerable artists; but it must be remembered, that it was not by these defects they acquired their reputation; they have a right to our pardon, but not to our admiration.

However, to imitate peculiarities or mistake defects for beauties, that man will be most liable, who confines his imitation to one favourite master; and even though he chooses the best, and is capable of distinguishing the real excellences of his model, it is not by such narrow practice, that a genius or mastery in the art is acquired. A man is as little likely to form a true idea of the perfection of the art, by studying a single artist, as he would be to produce a perfectly beautiful figure, by an exact imitation of any individual living model. And as the painter, by bringing together in one piece, those beauties which are dispersed among a great variety of individuals, produces a figure more beautiful than can be found in nature, so that artist who can unite in himself the excellences of the various great painters, will approach nearer to perfection than any one of his masters. He, who confines himself to the imitation of an individual, as he never proposes to surpass, so he is not likely to equal, the object of his imitation. He professes only to follow; and he that follows must necessarily be behind.

We should imitate the conduct of the great artists in the course of their studies, as well as the works which they produced, when they were perfectly formed. Raffaelle began by imitating implicitly the manner of Pietro Perugino, under whom he studied; hence his first works are scarce to be distinguished from his master’s; but soon forming higher and more extensive views, he imitated the grand outline of Michael Angelo; he learned the manner of using colours from the works of Leonardo da Vinci, and Fratre Bartolomeo: to all this he added the contemplation of all the remains of antiquity that were within his reach; and employed others to draw for him what was in Greece and distant places. And it is from his having taken so many models, that he became himself a model for all succeeding painters; always imitating, and always original.
