once for all be cleared up. The index of this work will form a new Dictionary of Painters, certainly more copious, and perhaps more accurate than usual, although it might be still further improved, especially by consulting archives and manuscripts.[14]
The second object which I had in view was to advance the interests of the art as much as lay in my power. It was of old observed that examples have a more powerful influence on the arts than any precepts can possess; and this is particularly true in respect to painting. Whoever writes history upon the model of the learned ancients, ought not only to narrate events, but to investigate their secret sources and their causes. Now these will be here developed, tracing the progress of painting as it advanced or declined in each school; and these causes being invariable, point out the means of its improvement, by shewing what ought to be pursued and what avoided. Such observations are not of importance to the artist alone, but have a reference also to other individuals. In the Roman school, during its second epoch, I perceive that the progress of the arts invariably depends on certain principles universally adopted in that age, according to which artists worked, and the public decided. A general history, by pointing out the best maxims of art, may contribute considerably to make them known and regarded; and hence artists can execute, and others approve or direct, on principles no longer uncertain and questionable, nor deduced from the manner of a particular school, but founded on maxims unerring and established, and strengthened by the uniform practice of all schools and all ages. We may add, that in a history so diversified, numerous examples occur suited to the genius of different students, who have often to lament their want of success from this circumstance alone, that they had neglected to follow the path in which nature had destined them to tread. On the influence of examples I shall add no more: should any one be desirous also of precepts under every school, he will find them given, not indeed by me, but by those who have written more ably on the art, and whom I have diligently consulted with regard to different masters, as I shall hereafter mention.
My third object was to facilitate an acquaintance with the various styles of painting. The artist or amateur indeed, who has studied the manner of all ages and of every school, on meeting with a picture can very readily assign it, if not to a particular master, at least to a certain style, much as antiquarians, from a consideration of the paper and the characters, are enabled to assign a manuscript to a particular era; or as critics conjecture the age and place in which an anonymous author flourished, from his phraseology. With similar lights we proceed to investigate the school and era of artists; and by a diligent examination of prints, drawings, and other relics belonging to the period, we at length determine the real author. Much of the uncertainty, with regard to pictures, arises from a similitude between the style of different masters: these I collect together under one head, and remark in what one differs from the other. Ambiguity often arises from comparing different works of the same painter, when the style of some of them does not seem to accord with his general manner, nor with the great reputation he may have acquired. On account of such uncertainty, I usually point out the master of each artist, because all at the outset imitate the example offered by their teachers; and I, moreover, note the style formed, and adhered to by each, or abandoned for another manner; I sometimes mark the age in which he lived, and his greater or less assiduity in his profession. By an attentive consideration of such circumstances, we may avoid pronouncing a picture spurious, which may have been painted in old age, or negligently executed. Who, for instance, would receive as genuine all the pictures of Guido, were it not known that he sometimes affected the style of Caracci, of Calvart, or of Caravaggio; and at other times pursued a manner of his own, in which, however, he was often very unequal, as he is known to have painted three or four different pieces in a single day? Who would suppose that the works of Giordano were the production of the same artist, if it were not known that he aspired to diversify his style, by adopting the manner of various ancient artists? These are indeed well known facts, but how many are there yet unnoted that are not unworthy of being related, if we wish to avoid falling into error? Such will be found noticed in my work, among other anecdotes of the various masters, and the different styles.
I am aware that to become critically acquainted with the diversity of styles is not the ultimate object to which the travels and the eager solicitude of the connoisseur aspire. His object is to make himself familiar with the handling of the most celebrated masters, and to distinguish copies from originals. Happy should I be, could I promise to accomplish so much! Even they might consider themselves fortunate, who dedicate their lives to such pursuits, were they enabled to discover any short, general, and certain rules for infallibly determining this delicate point! Many rely much upon history for the truth. But how frequently does it happen that the authority of an historian is cited in favour of a family picture, or an altar-piece, the original of which having been disposed of by some of the predecessors, and a copy substituted in its place, the latter is supposed to be a genuine painting! Others seem to lay great stress on the importance of places, and hesitate to raise doubts respecting any specimen they find contained in royal and select galleries, assuming that they really belong to the artists referred to in the gallery descriptions and catalogues. But here too they are liable to mistake; inasmuch as many private individuals, as well as princes, unable to purchase ancient pictures at any price, contented themselves with such copies of their imitators as approached nearest to the old masters. Some indeed were made by professors purposely despatched by princes in search of them; as in the instance of Rodolph I., who employed Giuseppe Enzo, a celebrated copyist. (See Boschini, p. 62, and Orlandi, on Gioseffo Ains di Berna.) External proofs, therefore, are insufficient, without adding a knowledge of different manners. The acquisition of such discrimination is the fruit only of long experience, and deep reflection on the style of each master: and I shall endeavour to point out the manner in which it may be obtained.[15]
To judge of a master we must attend to his design, and this is to be acquired from his drawings, from his pictures, or, at least, from accurate engravings after them. A good connoisseur in prints is more than half way advanced in the art of judging pictures; and he who aims at this must study engravings with unremitting assiduity. It is thus his eye becomes familiarized to the artist's method of delineating and foreshortening the figure, to the air of his heads and the casting of his draperies; to that action, that peculiarity of conception, of disposing, and of contrasting, which are habitual to his character. Thus is he, as it were, introduced to the different families of youths, of children, of women, of old men, and of individuals in the vigour of life, which each artist has adopted as his own, and has usually exhibited in his pictures. We cannot be too well versed in such matters, so minute or almost insensible are the distinctions between the imitators of one master, (such as Michelangiolo, for example,) who have perhaps studied the same cartoon, or the same statues, and, as it were, learned to write after the same model.
More originality is generally to be discovered in colouring, a branch of the art formed by a painter rather on his own judgment, than by instruction. The amateur can never attain experience in this branch who has not studied many pictures by the same master; who has not observed his selection of colours, his method of separating, of uniting, and of subduing them; what are his local tints, and what the general tone that harmonizes the colours he employs. This tint, however clear and silvery in Guido and his followers, bright and golden in Titiano and his school, and thus of the rest, has still as many modifications as there are masters in the art. The same remark extends to middle tints and to chiaroscuro, in which each artist employs a peculiar method.
These are qualities which catch the eye at a distance, yet they will not always enable the critic to decide with certainty; whether, for instance, a certain picture is the production of Vinci, or Luini, who imitated him closely; whether another be an original picture by Barocci, or an exact copy from the hand of Vanni. In such cases judges of art approach closer to the picture with a determination to examine it with the same care and accuracy as are employed in a judicial question, upon the recognition of hand-writing. Fortunately for society, nature has granted to every individual a peculiar character in this respect, which it is not easy to counterfeit, nor to mistake [Pg xxviii]for any other person's writing. The hand, habituated to move in a peculiar manner, always retains it: in old age the characters may be more slowly traced, may become more
